What is a Cataract and How Does It Affect Your Vision?
A cataract develops when the natural lens of your eye, which sits just behind the coloured part (iris), becomes cloudy or opaque. In a healthy eye, the lens is clear and allows light to pass through easily, focusing it on the retina at the back of the eye to form a sharp image. When a cataract forms, this lens gradually loses its transparency, scattering and blocking light before it reaches the retina. The result is that your vision becomes hazy, dim or blurred over time.
Understanding How Cataracts Develop
The lens of the eye is made up mostly of water and proteins. These proteins are arranged in a very precise manner that keeps the lens clear. As you age, these proteins begin to break down and clump together, forming small cloudy patches on the lens. This is the beginning of a cataract. Over time, these patches grow larger and affect more of the lens, making your vision progressively worse.
Think of it as looking through a frosted or fogged-up window. In the early stages, you can still see shapes and outlines, but fine details become harder to make out. As the cataract matures, even basic shapes can become difficult to distinguish. In advanced cases, the cataract can become so dense that it blocks almost all light from entering the eye, significantly reducing vision.
Several factors accelerate this process. Prolonged exposure to ultraviolet (UV) light from the sun, diabetes, smoking and certain medications can speed up the changes in lens proteins. In India, where many people work outdoors in strong sunlight and where diabetes prevalence is rising, understanding cataract causes is particularly relevant. Knowing what causes cataracts can help you take steps to slow their progression, even if they cannot be prevented entirely.
What are the Common Cataract Symptoms You Should Watch For?
Cataract symptoms tend to develop gradually, which is why many people adapt to the changes without realising their vision is deteriorating. Recognising these cataract symptoms early is valuable because timely cataract diagnosis allows you and your doctor to plan the appropriate course of action. Below are the most frequently reported cataract symptoms.
Common Cataract Symptoms
| Symptom | What It Feels Like |
��️ | Blurred or cloudy vision | Everything looks slightly hazy, as though you are looking through a dirty or fogged-up glass. This is often the earliest and most common sign of a cataract. |
�� | Increased sensitivity to light | Bright lights, sunlight or car headlights feel uncomfortably glaring. You may find yourself squinting more than usual. |
�� | Difficulty seeing at night | Night driving becomes challenging because oncoming headlights create halos or starbursts. Dim environments feel much darker than they used to. |
�� | Fading or yellowing of colours | Colours appear less vivid or take on a yellowish or brownish tint. White surfaces may look slightly yellow. |
�� | Frequent changes in spectacle prescription | You may need new glasses more often than before, and each new prescription does not seem to help as much as it should. |
�� | Difficulty reading or doing close work | Fine print becomes harder to read even with reading glasses, and you may need significantly brighter light. |
�� | Double vision in one eye | You may see two overlapping images when looking through the affected eye alone. This is different from the double vision caused by eye muscle problems. |
✨ | Halos around lights | Rings of light appear around bulbs, streetlights and headlights, particularly noticeable at night or in low-light settings. |
Cataracts vs Age-Related Macular Degeneration (AMD)
Both cataracts and AMD are common in older adults, but they affect different parts of the eye and cause different patterns of vision loss.
Feature | Cataract | Age-Related Macular Degeneration (AMD) |
Part of eye affected | Lens (front of the eye) | Macula (central part of the retina at the back) |
Type of vision loss | Overall blurring, like looking through fog | Central vision loss, with peripheral vision intact |
Colour changes | Yellowing or fading of colours | Distortion of straight lines, dark patches in central vision |
Reversibility | Fully treatable with cataract surgery | Manageable but currently not fully reversible |
Age of onset | Commonly after 50, though it can occur earlier | Usually after 60 |
Pain | Painless | Painless |
Progression | Gradual clouding over months to years | Can be slow (dry AMD) or rapid (wet AMD) |
When Should You See a Doctor for Cataract Symptoms?
You should book an appointment with an eye specialist if you notice any of the following:
• Your vision has become noticeably blurred or hazy and new glasses do not help
• You are finding it difficult to drive, especially at night, due to glare from headlights
• Reading, cooking or other daily activities have become harder because of poor vision
• You are seeing halos or rings around lights that were not there before
• Colours look washed out, yellowish or different from how they used to appear
• You have had a sudden change in vision in one or both eyes
• You have diabetes and have not had an eye examination in the past year
• You are over the age of 50 and have not had a comprehensive eye check-up recently
At Vasan Eye Care, our specialists recommend a comprehensive eye examination at least once every two years after the age of 40, and annually after 50. Early cataract diagnosis means you can plan your cataract treatment before vision loss starts affecting your daily life.
What are the Different Cataract Types and How Do They Differ?
Not all cataracts are the same. The different cataract types are classified based on where the clouding occurs within the lens and what causes it. Understanding your specific type of cataract helps your doctor recommend the most suitable cataract treatment plan.
The Main Types of Cataract
- Nuclear Cataract (Nuclear Sclerotic Cataract) This is the most common type of cataract and develops in the centre (nucleus) of the lens. A nuclear cataract typically forms gradually over several years and is closely associated with ageing. In its early stages, it may actually cause a temporary improvement in near vision, sometimes called “second sight.” However, as the cataract progresses, the lens becomes increasingly yellow and then brown, causing significant blurring and a shift in colour perception. People with a nuclear cataract often report that whites appear yellowish and that colours seem less vibrant.
- Cortical Cataract A cortical cataract begins as whitish, wedge-shaped streaks or opacities on the outer edge (cortex) of the lens. These streaks slowly extend inward towards the centre, like the spokes of a wheel. As they grow, they scatter light entering the eye, which is why glare and difficulty with contrast are hallmark cataract symptoms of this type. Cortical cataracts are particularly common in people with diabetes and can affect both distance and near vision.
- Posterior Subcapsular Cataract (PSC) This type of cataract forms on the back surface of the lens, just beneath the lens capsule. A posterior subcapsular cataract tends to develop faster than other cataract types and can noticeably affect vision within months rather than years. It is especially troublesome for reading and close work, and it causes significant glare in bright light. PSC cataracts are more common in younger adults, people who use steroid medications for prolonged periods and those with diabetes.
- Congenital Cataract Some babies are born with cataracts or develop them during early childhood. Congenital cataracts may be caused by genetic factors, infections during pregnancy (such as rubella) or metabolic conditions. If a congenital cataract is dense enough to block vision, it typically requires cataract surgery in infancy to prevent amblyopia (lazy eye) and to allow normal visual development.
- Traumatic Cataract A traumatic cataract develops after an injury to the eye. This could result from a blunt impact, a penetrating wound or exposure to chemical substances. In India, eye injuries related to firecrackers (particularly around Diwali), industrial work and agricultural activities are notable cataract causes. A traumatic cataract may develop soon after the injury or years later.
- Secondary Cataract (Posterior Capsular Opacification) Strictly speaking, a secondary cataract is not a true cataract. It occurs when the thin membrane (capsule) left behind after cataract surgery becomes cloudy over time. This can happen months or even years after the original cataract surgery. The symptoms are similar to those of a cataract, including blurred vision and glare. It is easily treated with a brief, painless laser procedure called YAG capsulotomy.
What Causes a Cataract to Develop?
The most common cause of a cataract is the natural ageing process. Over time, the proteins in your eye’s lens break down and clump together, reducing the clarity of the lens. This process is similar to how an egg white changes from transparent to opaque when cooked: once the protein structure changes, it cannot return to its original clear state. While ageing is the primary factor, several other cataract causes can contribute to or accelerate this process.
Ultraviolet radiation from sunlight is a significant contributor. In India, where sunlight is strong for much of the year and many people spend extended hours outdoors for work or daily activities, cumulative UV exposure over decades plays a meaningful role. Smoking damages the lens proteins through oxidative stress, and research shows that smokers develop cataracts at a younger age compared to non-smokers. Diabetes is another major cataract cause because elevated blood sugar levels alter the chemical composition of the lens, leading to faster clouding.
Who is More Likely to Get Cataracts?
While anyone can develop a cataract, certain groups of people face a higher likelihood. Understanding these risk factors can help you be more vigilant about regular eye examinations and early cataract diagnosis.
Age over 50: The single most significant factor. The majority of cataracts are age-related, and the probability increases steadily after the age of 50. By the age of 75, most people will have some degree of cataract formation.
Diabetes: People with diabetes are two to five times more likely to develop cataracts, and they tend to develop them at a younger age. High blood sugar causes changes in the lens that speed up clouding.
Prolonged sunlight exposure: Those who work outdoors, such as farmers, construction workers and street vendors, accumulate more UV damage over their lifetime, increasing cataract risk.
Smoking and tobacco use: Smoking generates harmful free radicals that damage the lens proteins. Both cigarette smoking and chewing tobacco are linked to higher cataract rates.
Long-term steroid use: Medications such as corticosteroids (oral, inhaled or eye drops), when used over months or years, can cause posterior subcapsular cataracts.
Previous eye injury or surgery: Any trauma to the eye or a previous eye operation can increase the chance of developing a cataract in that eye.
Family history: If close relatives developed cataracts at a relatively young age, your own risk may be higher.
High myopia (severe short-sightedness): People with high myopia are more prone to certain cataract types, particularly nuclear and posterior subcapsular cataracts.
Excessive alcohol consumption: Regular heavy drinking has been associated with an increased risk of cataract formation.
Poor nutrition: A diet lacking in antioxidants and essential vitamins may contribute to earlier cataract development. This is relevant in parts of India where nutritional deficiencies remain common.
How Do Doctors Diagnose a Cataract?
Cataract diagnosis is carried out through a comprehensive eye examination by a qualified ophthalmologist. At Vasan Eye Care, our specialists use a series of tests to determine whether a cataract is present, how advanced it is and whether it is the primary cause of your vision problems. A thorough cataract diagnosis is essential because other eye conditions can cause similar symptoms, and it is important to identify the exact cause before recommending treatment.
The examination usually begins with a detailed discussion about your symptoms, medical history, medications and family history. Your doctor will ask about specific difficulties you are experiencing, such as trouble reading, driving at night or recognising faces. This conversation helps the specialist understand how the cataract is affecting your daily life, which is a key factor in deciding the timing of cataract treatment.
Core Tests Used in Cataract Diagnosis
- Visual Acuity Test: This is the standard eye chart test where you read letters of decreasing size from a set distance. It measures how clearly you can see and provides a baseline for monitoring changes over time.
- Slit-Lamp Examination: A slit-lamp is a specialised microscope that allows the doctor to examine the structures at the front of your eye in fine detail. By shining a thin, intense beam of light into your eye, the ophthalmologist can see the lens and identify the location, type and extent of the cataract. This examination is the most important step in cataract diagnosis.
- Dilated Eye Examination: Eye drops are used to widen (dilate) your pupils, giving the doctor a much better view of the lens and the retina behind it. This helps in assessing the severity of the cataract and also checks for other conditions such as macular degeneration or diabetic retinopathy that could affect visual outcomes after cataract surgery.
- Tonometry: This test measures the pressure inside your eye (intraocular pressure). While it does not directly diagnose a cataract, it helps rule out glaucoma, which can coexist with cataracts and influence the treatment approach.
- Biometry (A-Scan or Optical Biometry): If cataract surgery is being considered, precise measurements of the eye are taken to calculate the correct power for the artificial intraocular lens (IOL) that will replace your natural lens. Modern optical biometry devices provide highly accurate measurements, which are essential for achieving a good visual outcome after surgery.
- Optical Coherence Tomography (OCT): In some cases, an OCT scan may be performed to examine the retina in detail. This is particularly useful when the cataract is not dense enough to fully explain the level of vision loss, as it can reveal underlying retinal problems.
At Vasan Eye Care, cataract diagnosis is carried out using advanced diagnostic equipment at all our 150+ centres. The entire examination is painless and typically takes 30 to 60 minutes, including the time needed for your pupils to dilate.
What Does Cataract Treatment Look Like?
Cataract treatment depends on the type and stage of the cataract, how much it is affecting your daily life, and your overall eye health. In early stages, simple measures may be enough, while more advanced cataracts require surgery. In many cases, cataract treatment is a step-by-step process rather than a single intervention.
Cataract Treatment Options
- Updated Spectacle Prescription In the early stages of a cataract, a change in your glasses prescription may improve your vision sufficiently to manage daily tasks. Anti-glare coatings on lenses can help with light sensitivity, and using brighter reading lights can make close work easier. This is not a cataract treatment in the curative sense, but it can help you manage cataract symptoms while the condition is still mild. Your doctor will monitor the cataract at regular intervals and advise when surgery becomes appropriate.
- Phacoemulsification (Phaco Surgery) Phacoemulsification is the most widely performed cataract surgery technique worldwide. During this procedure, the surgeon makes a very small incision (typically 2.2 to 2.8 mm) in the cornea. An ultrasound probe is inserted through this incision to break the cloudy lens into tiny fragments, which are then gently suctioned out of the eye. A foldable artificial intraocular lens (IOL) is then inserted through the same small incision. The incision is self-sealing in most cases, meaning no stitches are required. The surgery is performed under local anaesthesia and usually takes 15 to 30 minutes.
- Micro-Incision Cataract Surgery (MICS) MICS is a refinement of phacoemulsification that uses an even smaller incision (less than 2.0 mm). This smaller incision can lead to faster healing, less induced astigmatism and a quicker return to normal activities. It requires specialised instruments and IOLs designed for micro-incisions. At Vasan Eye Care, MICS is available for suitable candidates after thorough evaluation.
- Femtosecond Laser-Assisted Cataract Surgery (FLACS) In this advanced approach, a femtosecond laser is used to perform some of the key steps of cataract surgery, including creating the corneal incision, making the opening in the lens capsule and softening the cataract before removal. The laser provides a high degree of precision and consistency. It is particularly beneficial in complex cases, such as dense cataracts or when a toric IOL is being implanted to correct astigmatism. The procedure is then completed using phacoemulsification to remove the lens fragments.
- Extracapsular Cataract Extraction (ECCE) ECCE involves a larger incision to remove the cloudy lens in one piece, rather than breaking it up first. This technique is used when the cataract is very dense or hard and cannot be easily broken down by ultrasound. While it requires a bigger incision and stitches, ECCE remains an important surgical option for mature cataracts. An IOL is implanted after the lens is removed. Recovery may take slightly longer compared to phacoemulsification.
- Intraocular Lens (IOL) Selection Choosing the right IOL is an integral part of cataract treatment planning. Several types of IOLs are available, including Monofocal IOL (provides clear vision at one fixed distance, usually far, with reading glasses likely needed after surgery), Multifocal IOL (designed to provide clear vision at multiple distances, reducing dependence on glasses), Toric IOL (corrects pre-existing astigmatism in addition to replacing the cataract), and Extended Depth of Focus (EDOF) IOL (provides a continuous range of vision from distance to intermediate, with less chance of glare compared to multifocal lenses). Your Vasan Eye Care specialist will discuss the advantages and limitations of each IOL type to help you make an informed choice based on your visual needs and lifestyle.
Cataracts and Diet: What Indian Foods Help?
India’s traditional diets are rich in foods that support eye health, and making mindful dietary choices can be beneficial if you have a cataract or are at risk of developing one. Foods high in vitamin C, such as amla (Indian gooseberry), guava, oranges and lemons, are powerful antioxidants that help protect the lens from oxidative damage. Amla, in particular, is one of the richest natural sources of vitamin C and has been valued in Ayurvedic tradition for its health benefits.
Leafy green vegetables like spinach (palak), fenugreek leaves (methi) and drumstick leaves (moringa) are excellent sources of lutein and zeaxanthin, two carotenoids that accumulate in the eye and help filter harmful blue light. Including these greens in your daily meals, whether in sabzi, dal or paratha, can contribute to long-term lens health. Carrots, sweet potatoes and pumpkin provide beta-carotene, which the body converts into vitamin A, essential for overall eye function.
Nuts and seeds such as almonds, walnuts and flaxseeds provide vitamin E and omega-3 fatty acids, both of which have antioxidant properties. Turmeric (haldi), a staple in Indian cooking, contains curcumin, which has anti-inflammatory and antioxidant effects. While no food can reverse a cataract, a balanced diet that includes these items may help slow cataract progression and support your overall eye health alongside regular check-ups at Vasan Eye Care.
Cataracts in the Indian Context
Cataract is the single largest cause of preventable blindness in India. According to various national surveys, cataracts account for a significant proportion of blindness and visual impairment across the country, particularly in rural areas where access to eye care services may be limited. The combination of high UV exposure due to India’s tropical and subtropical climate, rising diabetes prevalence, widespread tobacco use and nutritional challenges in some regions makes cataract a major public health concern.
India has made considerable progress in addressing this through initiatives such as the National Programme for Control of Blindness and Visual Impairment (NPCBVI) and the expansion of eye care services into smaller towns and rural areas. Vasan Eye Care, established in 2002 in Trichy, Tamil Nadu, has been part of this effort. With over 150 super speciality centres across India, Vasan Eye Care, as part of ASG Enterprises, brings advanced cataract diagnosis and cataract surgery closer to communities that previously had to travel long distances for quality eye care.
The cost of cataract surgery in India is significantly lower compared to many other countries, making it accessible to a broader population. Vasan Eye Care’s mission of ethical practices, transparency and value for money ensures that high-quality cataract treatment is within reach. If you or a family member has been experiencing vision changes, a comprehensive eye examination at your nearest Vasan Eye Care centre is a sensible first step.
Living with Cataracts: Practical Tips
If you have been diagnosed with a cataract but are not yet ready for surgery, or if your cataract is in its early stages, there are several practical steps you can take to manage your daily life more comfortably:
• Use bright, focused lights for reading, cooking and other close work. Adjustable desk lamps and LED bulbs that provide white light can make a noticeable difference.
• When going outdoors, wear sunglasses with full UV protection to shield your eyes from further sun damage and to reduce glare. A wide-brimmed hat provides additional protection.
• For reading and using your phone, increase the font size and adjust the brightness and contrast settings on your devices. Many smartphones have accessibility features specifically designed for people with visual difficulties.
• If night driving has become problematic due to glare from headlights, consider avoiding driving after dark when possible or planning routes that are well-lit. Keep your car windscreen and headlights clean, as dirt and smudges amplify the glare effect.
• At home, use contrasting colours to mark the edges of steps and keep walkways clear to reduce the risk of trips and falls.
• Attend your scheduled follow-up appointments at Vasan Eye Care so your specialist can monitor your cataract and let you know when cataract surgery would be beneficial.

Frequently Asked Questions (FAQs)
While no single food directly causes a cataract to worsen overnight, certain dietary choices may contribute to faster progression over time. It is advisable to limit your intake of refined sugars and highly processed foods, as these can increase oxidative stress in the body, including in the eye. Fried foods cooked in reused oil, which is common in some Indian street food preparations, contain high levels of trans fats and free radicals that can damage lens proteins. Excessive alcohol consumption is also associated with an increased cataract risk. If you have diabetes, managing your blood sugar through a controlled diet is especially important, as high sugar levels directly affect the lens. Instead, focus on eating fresh fruits, vegetables, green leafy items and foods rich in vitamins C and E, which support eye health.
As of today, there is no scientifically proven non-surgical method to remove or reverse a cataract. Once the proteins in the lens have become cloudy, no eye drop, medication, herbal remedy or exercise can restore them to their original clear state. You may come across claims about cataract-dissolving drops or natural cures, but these have not been validated by rigorous clinical research. In the early stages, updated glasses and lifestyle adjustments can help manage cataract symptoms, but cataract surgery remains the only definitive cataract treatment. Research into potential medical treatments for cataracts is ongoing, and your Vasan Eye Care doctor can keep you informed about any future developments.
While you cannot stop a cataract from progressing entirely, several measures may slow the process. Wearing good-quality sunglasses with UV protection when outdoors is one of the most practical steps, particularly in India where sunlight is strong. If you smoke or use tobacco, quitting can reduce the oxidative damage to your lens. Managing diabetes effectively through diet, exercise and medication helps control blood sugar levels that accelerate cataract formation. Eating a balanced diet rich in antioxidants, including leafy green vegetables, citrus fruits and nuts, supports overall lens health. Having regular eye examinations allows your doctor to track the cataract and advise you on the appropriate time for cataract surgery.
Living with a cataract can be frustrating, especially as the condition progresses. In the early stages, you might notice that you need stronger lighting for reading or that night driving has become uncomfortable due to glare. Colours may appear slightly dull, and you may find yourself holding your phone or newspaper further away or closer than before. As the cataract advances, these difficulties increase. Many people report feeling less confident about driving, cooking or moving around unfamiliar environments. Social activities can become less enjoyable when you cannot see faces clearly or follow what is happening on a television screen. It is important to remember that these changes are gradual, treatable and not a normal part of ageing that you must simply accept. Cataract surgery can restore clear vision and significantly improve your quality of life.
Modern cataract surgery, particularly phacoemulsification, typically takes between 15 and 30 minutes. The procedure is performed under local anaesthesia, usually administered as eye drops or a small injection around the eye, so you will not feel pain during the surgery. You may feel a mild sensation of pressure and see some lights, but the experience is generally comfortable. Most patients are surprised by how quick and straightforward the process is. After the surgery, mild discomfort, a gritty feeling or slight irritation is normal and usually settles within a few days with prescribed eye drops.
Most people notice a significant improvement in their vision within a day or two after cataract surgery. Light activities such as walking, watching television and eating can usually be resumed the same day. However, your doctor will advise you to avoid strenuous activities, heavy lifting and bending forward for about two to four weeks. Swimming and exposure to dusty environments should be avoided during the recovery period. Driving can typically be resumed once your doctor confirms that your vision meets the required standard, which is usually within a week or two. Complete visual stabilisation may take four to six weeks, during which time your final spectacle prescription (if needed) will be determined.
A cataract cannot come back after cataract surgery because the natural lens has been permanently removed and replaced with an artificial intraocular lens (IOL). However, some patients develop a condition called posterior capsular opacification (PCO), sometimes referred to as a “secondary cataract.” This happens when the thin membrane that holds the IOL in place becomes cloudy over time. PCO can cause symptoms similar to the original cataract, such as blurred vision and glare. The good news is that PCO is easily and quickly treated with a painless laser procedure called YAG capsulotomy, which takes just a few minutes and restores clear vision.
There is no fixed rule about when cataract surgery must be performed. The right time depends on how much the cataract is affecting your daily life and activities. In the past, patients were often advised to wait until the cataract was “mature” or “ripe,” but modern cataract surgery techniques allow for safe removal at any stage. If your cataract is making it difficult for you to read, drive, work or enjoy your daily routine, it is a good time to discuss surgery with your doctor. At Vasan Eye Care, our specialists will assess your individual situation and help you decide the most appropriate timing for your cataract treatment.
