Blurred or hazy vision
Faces, print and road signs look less distinct despite cleaning spectacles or updating the prescription.
Recognise the change • Confirm the cause
Is cataract changing how you see?
Cataract often develops quietly. Vision may become hazy, colours less vivid and headlights more troublesome—yet similar symptoms can come from other eye conditions. A complete examination establishes what is actually responsible.

Daytime haze
Night glareCommon visual changes
Cataract does not always feel like a “cloud”
Symptoms usually develop gradually and may differ between the two eyes. A new spectacle prescription can help for a time, but increasing lens opacity eventually limits the improvement glasses can provide.
Glare and halos
Headlights, sunlight or bright indoor lighting scatter more, making night driving uncomfortable.
Faded colour and contrast
Colours appear duller, whites may look yellowed and low-contrast objects become harder to distinguish.
Poorer vision in dim light
Steps, faces and objects may be harder to see in restaurants, evenings or poorly lit rooms.
More light needed to read
Reading and detailed work require stronger illumination, larger print or more frequent pauses.
Ghosting or double vision
A second or “ghost” image may remain in one eye even when the other eye is covered.
Do not assume a sudden change is cataract. Sudden loss of vision, a curtain or shadow, new flashes or a shower of floaters, severe pain, marked redness or injury requires urgent eye assessment. Call Delhi Eye Care on +91 92208 92424.
An important distinction
Blur does not always mean cataract
A cataract is one possible cause of reduced vision. Dry eye, an outdated spectacle prescription, corneal disease, glaucoma, macular disease and retinal conditions can produce overlapping complaints.
The key question during assessment is not only “Is there a cataract?” but also “Does the cataract explain the degree and pattern of visual difficulty?”
Finding a cataract does not prove that it is the only cause of reduced vision. Examining the back of the eye is essential—particularly in diabetes, glaucoma, high myopia or previous retinal disease.
Sudden rather than gradual
Rapid visual loss suggests another cause and should be assessed promptly.
Pain or marked redness
Age-related cataract is usually painless and does not typically cause a red eye.
Distortion or missing areas
Bent lines, a central patch or field loss may indicate macular, retinal or optic-nerve disease.
Flashes, floaters or a curtain
These are retinal warning symptoms—not routine features of cataract.
What the doctor sees
Cataract type helps explain the symptom pattern
More than one pattern may coexist, and the label alone does not determine when surgery is needed.
Nuclear
Central lens change, often associated with gradual distance blur, colour shift and prescription change.
Cortical
Spoke-like peripheral opacities that can scatter light and contribute to glare.
Posterior subcapsular
Often causes disproportionate glare and near-vision difficulty, sometimes at a younger age.
Your cataract evaluation
Diagnosis is more than checking the spectacle number
Dr. Nidhi Gupta and the DEC team assess whether cataract is present, how much it affects vision and whether another eye condition may influence the outcome.
Visual acuity at distance and near
Refraction and current spectacles
Slit-lamp examination
Eye-pressure measurement
Dilated retinal examination
Daily-activity and glare history
Listen to the visual problem
Driving, reading, screens, mobility and work demands establish the functional impact.
Measure vision and refraction
This shows how much clarity can still be recovered with an updated prescription.
Examine the whole eye
The cornea, cataract, eye pressure, optic nerve and retina are reviewed; dilating drops may be used.
Add tests only when useful
OCT, corneal topography, biometry or other investigations are selected according to the findings and surgical planning needs.
When is surgery considered?
The decision is based on your life and your eye—not one chart number
Cataract surgery is usually considered when visual difficulty affects useful activities despite appropriate spectacles, or when the cataract interferes with examination or treatment of another eye problem.
Observation may be reasonable
You remain comfortable and safe in daily activities, improved glasses are adequate, and examination shows no reason for earlier intervention.
Surgery may be appropriate
Blur or glare limits driving, reading, work, mobility or independence; spectacle changes no longer help enough; or the cataract restricts management of another eye condition.
Cataract does not need to become “ripe.” Equally, its presence alone does not make surgery urgent. The timing should have a clear functional or clinical reason.
Evaluation led by Dr. Nidhi Gupta
A diagnosis explained in plain language
Dr. Nidhi Gupta is Medical Director and leads cataract care at Delhi Eye Care. With over 18 years of experience and 15,000+ ophthalmic surgeries, her approach combines meticulous evaluation with careful counselling and post-operative follow-up.
“The presence of a cataract is only the first finding. We must confirm whether it explains the patient’s visual difficulty and what the rest of the eye allows us to achieve.”
Before your visit
Help us understand your vision more precisely
Bring your spectacles
Include the pair you use most and any recent prescription or eye records.
List your medicines
Mention eye drops, blood thinners, prostate medicines, diabetes treatment and drug allergies.
Describe the task that is difficult
Examples—night driving, small print, computer work, stairs, faces or sewing—are more useful than “vision is weak.”
Dilating drops may temporarily blur near vision and increase light sensitivity. If you are uncomfortable travelling afterwards, consider bringing an attendant and sunglasses.
Questions patients ask
Cataract symptoms and diagnosis: FAQs
Can cataract cause headache or eye pain?
Age-related cataract is usually painless. Headache may relate to visual strain or another cause, while significant eye pain requires assessment for conditions other than routine cataract.
Can cataract develop in only one eye?
Yes. Cataract may be present in both eyes but progress at different rates, or be more important in one eye because of injury, inflammation, medicines or other factors.
Can changing spectacles treat cataract?
An updated prescription may improve vision in earlier cataract, but glasses cannot remove lens opacity. When cataract limits useful vision despite appropriate correction, surgery is the definitive treatment.
Does cataract have to become mature before surgery?
No. Modern planning usually considers functional difficulty and eye health rather than waiting for a cataract to become very dense.
Why may OCT be advised before surgery?
OCT provides a cross-sectional view of the macula and can identify changes that may not be obvious from symptoms alone. It is used when clinical findings or risk factors make the information relevant.
Can an online symptom guide confirm cataract?
No. Symptoms overlap with other eye conditions. Confirmation requires examination by an eye specialist.
