Make a search on google 'bates eye exercise' you'll get instructions on how to do them
Its also necessary that you to progressively reduce the glass power.
I am ready for those exercises but can you tell me what they are??? thanks in advance
Taking small amounts of Vitamin A is good to eye, but will not help to reduce refraction errors for that you need to do some eye exercises regularly & progressively reduce the power of glasses needed.
Doing eye exercises & continually varying glass power's is a tedious job & it may take several months or years to completely get free of glasses.
