hi there, are you not thinking for another option like Lasik? Actually i also suffer 20 years of wearing thick glasses but last year i decided to undergo lasik and the outcome to me was amazing. I never expect that im gonna put my thick glass in the box, my vision now is 20/20 and i feel great about it. Just try to check http://www.my2020.com/ if you want to know more about lasik..God Bless you..
