Comprehensive Eye Test Simulator

A large interactive library of screening-style vision exercises. Each category contains 100 selectable test variations. A separate Eyesight Insight Lab uses grouped buttons for color blindness, astigmatism, focus, optical clarity, visual-field loss, retinal effects, and double vision without changing the test library itself.

Educational use only. These are screening-style simulations, not calibrated clinical tests. They cannot diagnose refractive error or eye disease. Sudden loss of vision, flashes, a curtain-like shadow, or new severe symptoms require prompt professional evaluation.

For one-eye testing, cover the other eye gently without pressing on it. Use corrective lenses unless you are deliberately comparing with and without correction.
