Glasses

I have to wear glasses, and I have one since a very young boy, so I have paid an arm and a leg every time I go for an eye test, so I am here once again just had my eyes tested, new glasses needed as  my eyes are getting worse, so after discounts £153, now maybe that is not to bad if you are on a wage where you can do some overtime to be able to buy them, but as a pensioner I am not able to do that so for some reason it always comes as a surprise to me that I need new ones,  for the past four years I  have brought the same frames, so I now have four pairs, and I have just ordered a set of prescription sun glasses as I am having problems with bright white items walls, doors that sort of thing, so it seemed logical that I should by a pair mainly because there was a 50%  discount,  as I came home I realised I will now have five sets of frames that are all the same all in good condition just the lenses are no good, well in the last three pairs, why is it that you are unable to re-use perfectly good frames?, why is this?, why do I have to pay a starting cost of £85 every time I sit down in the opticians?, I asked the last time about the many frames that I have I was told to donate them to the third world, that is really not the answer I was looking for!!!, I understand that the third world need sets of glasses I am not surprised that they need them as they with out a doubt would never be able to afford to buy a set with the prices that we are charged in this country, I really find it a rip off, and to finish off you have to pay up front and have to wait 14 days to get them a bit of a joke as far as service goes, I will have to try and remember this year to add this cost to the Christmas Present bill this year.
