EyeTest Online

EyeTest Online provides a suite of free, browser-based vision screening tests that can be taken from the comfort of your home. The platform includes tests for visual acuity (Snellen-style), astigmatism (radial line chart), color blindness (Ishihara-style plates), contrast sensitivity, visual field (peripheral vision), and central vision (Amsler grid). Each test is designed to be completed in minutes with clear instructions, and results are provided immediately as a reference. The tool works on both mobile and desktop devices, requires no sign-up, and is available in multiple languages (English, Spanish, German, French, Portuguese). It is intended as a screening aid and not a replacement for professional eye exams.
