Proof 1 Without the use of the prescription glasses (minus lens), myopia seldom progresses beyond -3.00D. It will normally stay below -2.00D which most people can live with. The following are the human proof of this theory.

This is just a small portion of the data we have. More proofs will be listed here. If you do your own observation/study/survey on the people around you (your relatives, friends, classmates, teachers, professors, colleagues, co-workers, patients or myopes in your office, parents of your children's classmates or friends, stranger you meet at the grocery store/ bus station/airport), you will find that those who wear their glasses all the time since childhood have medium or high myopia and those who only wear their glasses when it is necessary (for driving, classroom board, etc.) have low myopia. Again, myopes from all over the world prove this theory.
