I've stopped wearing my new ones, I tried them for a few weeks and couldn't work out why I kept getting headaches so I'm back with my old ones and it's magically gone away. Can't be bothered to argue any more with the opticians who are always convinced they are right and you are wrong. I'm not getting any more, I'm just going to get my eyes lasered and be done with. Glasses are a pain in the ****, end of.
it's indefinate nowadays
previously they shaved the lens at the front, so it grew back
nowadays they open it up and take a chunk out of the middle, so it lasts for ever
that's the way i see it anyway, no pun intended.
I'd rather have the 10" CRT that I can look at, rather than the 35" TFT that pokes me in the eye in the morning .
takes a while for me to adjust to new lenses, how long this takes depends just how much my prescription has been increased....next one will be big, i havent been in 1 1/2 years. may also have to fork out for lenses that are thinned aswell, as my current ones are thick enough around the edges, stronger ones are just going to be mad
i can only hope one day soon my eyes stabilise so i can get the damn things zapped
