Eye Recovery Training is a free iPhone app developed by Osawa Shunsuke. It falls under the Lifestyle category and specifically targets Health & Fitness. This app utilizes a Gabor patch to train eyesight and is recommended for individuals with myopia, hyperopia, and presbyopia.

The main feature of Eye Recovery Training is the game where users need to find the same Gabor patch image from a set of Gabor patch images. The objective is to compete and see how many times you can find the same image within a span of 3 minutes. It is recommended to play this game for 3 minutes every day for a month to achieve the desired eyesight improvement.

In addition to the game, the app also offers a measurement of eyesight level. Users can measure their eyesight level and check if there has been any improvement after one month of using the app.

It's important to note that Eye Recovery Training is intended to aid in the restoration of vision and does not guarantee effectiveness. It is advisable to seek medical advice before making any medical decisions.
