my right eye is 180degree and my left eeye has no degree. how to improve eyesight by excersise on my right eye.
I don't understand your use of "degree." 180 degrees from left to right would mean your zero degree eye (left) would be the problem. Why would you exercise your right eye?
If one eye has a lesser degree of peripheral vision than the other, you should see a doctor to diagnose the cause and treat it as the doctor instructs.
