Whether myopia or hyperopia, we usually only do far vision test. After training, if the far vision is improved, the near vision will also improve.
The following describes the examination of distant vision.
Please purchase the far vision test form by yourself.
- Remove the glasses. If it is not convenient to take out the lens, you can also wear the lens for testing.
- Whether you practice two eyes or one eye, you should test both eyes respectively.
- The following test method just for refer, you can use your local method.
- First test the right eye, cover the left eye, and remember the value of the line that is completely clear, such as 0.8, and the number of clear letters in the next line, such as 5, and record as 0.8 + 5.
- Test the left eye with the same method as the right eye.
