How to Use the Cataract & Glaucoma Risk Checker
Cataracts and glaucoma are both common age-related eye conditions, but they progress in very different ways. This checker asks 6 questions — age group, blurred/foggy vision, glare, narrowing peripheral vision, family history of glaucoma, and high myopia or diabetes — and calculates cataract risk and glaucoma risk separately.
Cataracts cloud the eye's lens, making everything look hazy or foggy overall, with worsening glare and halos around lights at night. Glaucoma, by contrast, gradually damages the optic nerve, usually narrowing peripheral vision first while central vision stays intact early on — making it hard to notice on your own, and any damage that occurs cannot be reversed, which is why early detection matters so much.
This result is a reference risk check only and does not replace medical diagnosis — an actual diagnosis requires a slit-lamp exam, eye pressure measurement, and retinal/visual field testing at an eye doctor's office. If your risk is high, or you're 40 or older, a comprehensive eye exam every 1-2 years is recommended even without noticeable symptoms.
Frequently Asked Questions
Cataracts cloud the eye's lens, making everything look hazy or foggy overall, with worsening glare, especially around lights at night. Glaucoma damages the optic nerve, usually narrowing peripheral (side) vision first, which is hard to notice on your own.
Optic nerve damage from glaucoma cannot be reversed, and central vision often stays intact early on, so there are few noticeable symptoms. Regular eye pressure checks and optic nerve exams help catch it early and slow its progression.
No. This result is a reference risk check only — an actual diagnosis requires a slit-lamp exam, eye pressure measurement, and retinal/visual field testing at an eye doctor's office. If your risk is high, schedule a comprehensive eye exam.
