For my 18th Birthday my friends gave me a gift voucher for Sunglass Hut (i live in Australia) and with that (plus some other money) i purchased a pair of Ray Ban Aviator Sunnies. In my experience i have had no problems with them so far except that i need prescription glasses for shortsightedness. So its either wear normal glasses or contacts with glasses. I was wondering is it possible to get the gold tinted lens in my Ray Bans replaced with presciption lens and if so how much would it cost, how much can i get back off a private medical membership and how much can i get back off tax???? Any and all responses greatly appreciated as i find it very annoying in my current situation.
