how much do eye glasses cost?!

It depends on your prescription and the frames you buy. Many optical stores offer special deals on discontinued frames so you could probably purchase a pair of glasses for anywhere between $100-to well over $1000. The higher end would be the cost of some very fancy frames.

If you have a recent prescription (less than 1 year old) and can prove you can't afford eye glasses, google your nearest Lions Club or nearest "town or city and free glasses"

If you're under 16 in the uk free other weise it depends ￡10 to ￡60

life goes its way. you cant change it
