What Is a Visual Acuity Test?
A visual acuity test measures the sharpness of your vision. The most well-known version is the Snellen chart, where letters decrease in size row by row. This online tool uses a similar concept: it displays random letters at progressively smaller sizes and records how many you identify correctly.
How This Test Works
You will see a single letter displayed at decreasing sizes across eight levels. For each level, choose the letter you see from the options provided. The tool tracks your accuracy and provides a summary score at the end. Sit about 60 cm (2 feet) from your screen for the best results.
Important Notes
Screen-based vision tests cannot replace a comprehensive eye examination. Factors like screen brightness, resolution, and viewing distance affect the results. Use this tool as a fun screening only, and schedule an appointment with an optometrist or ophthalmologist for a proper evaluation.
Frequently Asked Questions
Is this test accurate?
No. This is a simplified simulation for informational and entertainment purposes. It cannot diagnose vision problems. A proper eye exam uses calibrated equipment under controlled conditions.
How far should I sit from the screen?
For best results, sit approximately 60 cm (about 2 feet) from your monitor. Keep the screen at eye level and ensure good lighting without glare.
