It is believed that if a person with poor vision does not wear glasses, his vision will get worse. But that is far away from truth.
According to the Institute the main causes of poor vision are – reading, watching TV and Computer. In reading eyes are focused on the object at a fixed distance. The eyes get used to focusing on objects at a particular distance. That is the reason that people who did not learnt to read, did not have poor vision.
The mistake that the Institute makes is that they recommend the eye exercises for 30-45 minutes. I did try eye exercises for such periods of time. Since the impact can be felt in few seconds after exercises one feels may be more is better. The only change I would suggest is to do the eye exercises for 1 minutes at a time. One can repeat the exercise 10-15 times in a day with a minimum of 30 minutes gap between two exercises.
Second the most important aspect is to correct the physical deformity of the eye ball. So the exercises suggesting pressure points is another good thing.
