Next month I'll be 43. I have been diagnosed with hereditary astigmatism. So I wore glasses for a couple of months, but it got worse. Then I read somewere that wearing glasses actually brings more damage than benefit because the eye is adapting to different surroundings and becomes dependent on the glasses. In time , the eye becomes more and more damaged and it is necessary to change the diopter to the end of life. So I started with a healtier diet, mostly more vegetables in raw form, carrot, lemon, olive oil (not too much), garlic ( with lemon juice and olive oil 30min. before breakfast, to avoid bad odor), wheatgrass (I make myself). It is also necessary to check eye pressure, sometimes it is ( temporary!!!) cause of the blurred vision, especially in children in puberty. Best of luck...
