if you're referring to presbyopia - the age related loss of flexibility in your lenses that everyone will get, mine started around 42-43. I'm 51 and it seems to have leveled off in the last 3-4 years. I don't like reading glasses, so I got a prescription for progressive glasses about 7 years ago. I like the because they're always on and i don't have to fumble with them like you do with reading glasses.
I also suggest the Costco route as you can spend a lot of money on eye exams from a specialized clinic when in this case, they'll be doing a very routine test to determine what strength you need.
I'm about to turn 49 and have put it off way to long. I have to go renew my drivers license in december so i need to get some contacts or glasses or lasik or something before then.
Who all wears glasses? Im thinking of going to costco to get some contacts and a prescription and then buy some cool frames online for the short term. How long did you wait to get glasses?
