What Can You Test?

How the Online Eye Test Works

The visual-acuity test displays progressively smaller letters. You test the right eye, left eye, and both eyes while following the recommended viewing-distance instructions.

Results are displayed using familiar Snellen-style screening levels such as 20/20, 20/40, 20/80, and similar values.

Accessible Vision Testing

PeekVision.io also offers an Accessible Vision Test for people who have difficulty using the standard screening.

This version starts with larger letters, uses a high-contrast display, offers spoken instructions, and allows users to speak the five letters shown on the screen.

What Does 20/20 Vision Mean?

20/20 is commonly used as a reference level for normal distance visual acuity. A result such as 20/40 means that the tested person needs a larger letter size than someone who can read the 20/20 line under comparable testing conditions.

Is an Online Eye Test a Diagnosis?

No. An online eye test is a screening tool and cannot diagnose eye disease or determine an eyeglass prescription.

PeekVision.io provides preliminary browser-based vision screening only. Results are not a medical diagnosis or prescription and do not replace a comprehensive eye examination.

When Should You Have a Professional Eye Examination?

Consider professional evaluation if your screening repeatedly shows reduced vision, one eye performs significantly differently from the other, or you have concerns about your eyesight.

Sudden vision loss, severe eye pain, new flashes or floaters, or eye injury should be evaluated promptly by a qualified eye-care professional.
