Eye Test Chart - Check Your Visual Acuity Online
Check your visual acuity with our online eye test chart. This screening tool helps you assess your distance vision and determine if you might benefit from an eye examination.
What Is This Test?
The Eye Test Chart is a visual acuity screening tool based on traditional eye charts used by optometrists. It displays letters in decreasing sizes across 7 lines, allowing you to assess your ability to see clearly at a distance. While not a replacement for professional eye exams, it provides a quick way to check your vision.

Understanding Your Results
The smallest line you can read clearly indicates your visual acuity level. If you can read most lines clearly, your distance vision is likely good. Difficulty reading larger lines may indicate you need corrective lenses or an updated prescription. This is a screening tool only—consult an eye care professional for accurate diagnosis.
Frequently Asked Questions
Is this as accurate as a real eye exam?
No, this is a basic screening tool, not a comprehensive eye exam. Professional eye exams test many aspects of vision health beyond just visual acuity. Use this test for general screening, but see an optometrist or ophthalmologist for accurate diagnosis and prescription.
How far should I sit from the screen?
For best results, sit at your normal viewing distance from the screen (typically 20-24 inches for computer monitors). The test is calibrated for standard screen viewing distances, though results may vary based on your screen size.
When should I see an eye doctor?
If you have difficulty reading the larger lines, experience blurry vision, frequent headaches, eye strain, or notice changes in your vision, schedule an appointment with an eye care professional. Regular eye exams are recommended every 1-2 years.
