i already have very bad myopia. literally 700 800 deg. how??

I have read that Atropine eye drops may be effective in slowing down the progression of myopia. There is also the option of Ortho-K lenses. Best to speak to a doctor for advice. :) For more information on Atropine eye drops: http://www.healthxchange.com.sg/healthyliving/childrenhealth/Pages/childhood-myopia-eye-drops.aspx
