Think you are only the second person I've met with worse eyesight than me. I rely on my contact lenses and have got a really old pair of specs for if I get an eye infection. I do need to get some more glasses really though although will be spending considerably less than £600!
aye & that £600 was with my £240 discount off!!! (optical express)..I need new glasses too. Can't remember how much they were the last time, but I would have thought max £400 for designer + spare pair in Vision Express! I try to make them last as long as poss, despite the optician getting pushy anytime the prescription changes a tiny bit.
took out the insurance as well, insurance deal is a lot better now, £25 for 2 years and covers you for 80% of the cost.
to be fair, my presciption did change a wee bit last year, but the optician said the change was so slight not to spend the money on new specs at that time (this was when i was going through my yearly contact lens check)..so probably about 3.5/4yrs since my last complete new pair of glasses/lenses.
my last few frames have been designer, did try on a couple this time, but wasn't much that took my fancy or they had the big **** off logo on the side ended up getting those flexitron ones that seem pretty indestructible...we shall see!!
