Best Ophthalmologist Doctors

Adults aged 20-39 should have a comprehensive eye exam every 5 years if asymptomatic. From age 40-54, every 2-4 years. From 55-64, every 1-3 years. After 65, every 1-2 years. Diabetics should have an annual dilated eye exam regardless of age, as diabetic retinopathy can develop without symptoms.

An Ophthalmologist is a medical doctor (MBBS + MS/MD Ophthalmology) who can diagnose diseases, prescribe all medications, and perform eye surgery. An Optometrist holds a degree in optometry and primarily performs eye exams, prescribes glasses and contact lenses, but does not perform surgery.

Prolonged screen time causes digital eye strain (headaches, dry eyes, blurred vision) but does not cause permanent damage. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Use lubricating eye drops, adjust screen brightness, and maintain proper distance from screens.

Open-angle glaucoma (the most common type) often has no early symptoms — it silently damages the optic nerve. By the time vision loss is noticed, significant irreversible damage may have occurred. Regular eye exams with intraocular pressure measurement and optic disc evaluation are essential for early detection.
