Visual acuity is a measure of visual ability, used to determine whether or not a person is able to see and distinguish between objects. It is one of the components of vision.

In this app, we have developed a new, easy-to-use tool for measuring visual acuity. It is not a test that requires any equipment or expert skills. It is designed to help eye care professionals and ophthalmologists measure and identify patients with vision problems.

If you have a problem with your eyesight, we recommend that you see an ophthalmologist or an eye care professional.

Our tool can be used to measure visual acuity in both eyes, and the results can be used to make a decision about whether or not you should be treated for vision problems.

If you are using the app for the first time, you will need to perform the forced manual calibration, as described here.

It is important to keep the application up to date at all times so that you receive the latest technical updates.
