Disease Vision Simulator

Experience how common eye conditions affect sight — from the subtle haze of early cataracts to the central blind spot of advanced macular degeneration.

About These Conditions

Quick reference notes on common eye conditions and standard treatment paths.

☁️ Cataracts

Clouding of the eye's natural lens, causing blurred vision, halos around lights, and faded colors.

1 in 6people over 40 are affected

Treatment: Surgical lens replacement (phacoemulsification).

🔦 Glaucoma

Damage to the optic nerve, often linked to elevated intraocular pressure, causing gradual peripheral vision loss.

Over 70Mpeople affected globally

Treatment: Eye drops, laser therapy, or surgery to lower pressure and halt progression.

🕳️ Macular Degeneration (AMD)

Deterioration of the macula (central retina), causing a central blind spot while peripheral vision remains.

Dry AMDis most common (90%)

Treatment: Anti-VEGF injections for wet AMD; nutritional supplements may slow dry AMD.

💧 Diabetic Retinopathy

Damage to retinal blood vessels caused by high blood sugar, leading to leakage, dark spots, and blurred vision.

1 in 3diabetics develop it

Treatment: Blood sugar control, laser photocoagulation, anti-VEGF injections, or vitrectomy.
