The Eye Examination App by Grebs Publishing is a free lifestyle app that allows users to perform a quick vision check using an ophthalmic chart. The app is designed to determine visual acuity without glasses. It is important to note that this app is not a drug and should not be used for self-medication. In case of serious vision problems, such as a decrease in severity, it is recommended to consult a physician for a professional diagnosis of eye disease.

The Eye Examination App is an experimental development for simple checking of refractive errors at home in just 5 minutes. It is not a professional tool for diagnosing eyesight. Long-term disregard of discomfort in the eyes can lead to serious pathological consequences. Users are advised to consult a doctor immediately for any manifestations of unpleasant symptoms such as reduced visual acuity, eye fatigue, or redness in the eyelids.
