Although getting your eyes checked by your nearest ophthalmologist is always the best option, online eye tests are an incredibly easy and completely free way to get an initial check-up. These free online eye tests help you understand your tired eyes and determine when it’s necessary to see a doctor.

Online Astigmatism Test

The first online eye test is the astigmatism test. In this test, the user is instructed to sit approximately one meter away from the screen. Gray patterns and visual instructions are then displayed on the screen, which the user must observe carefully.
After the test is complete, the full results are displayed directly on the screen, allowing the user to understand whether or not they have astigmatism.

Online Color Blindness Test

The second free online eye test is the color blindness test. This is a quick and easy test in which the user has to identify letters, numbers, or shapes hidden within patterns of different colors.
This test is based on the famous Ishihara Test, which was originally developed to detect color vision deficiency.

Ishihara Test Information

The original Ishihara Test consists of 38 plates that provide a thorough examination of color-related problems. The online test uses smaller, representative samples of these plates, which are helpful in identifying common types of color blindness.
The test results are displayed on the screen in real-time, along with helpful suggestions.

Vision Test (E Test / E-Game)

Next comes the vision test, also known as the E Test or E-Game. In this test, the letter ‘E’ appears on the screen in different sizes and orientations (up, down, right, left).
The user has to indicate the direction in which the ‘E’ is pointing. At the end of the test, the results related to visual acuity are displayed on a single screen.

Important Information

It is important to note that these online eye tests do not provide a complete medical diagnosis of any eye condition. They only offer preliminary indications, allowing you to understand your eye health and seek advice from an optometrist or ophthalmologist at the appropriate time.
