Money for old rope

I've been a hostage to opticians for years. I have bad eyesight. When I was very young my mother and father insisted on pointing out sheep and suchlike. I would stare into the middle distance, puzzled. My parents thought I was well down on the learning spectrum until the problem was diagnosed when I went to school. Nearly 8 diopters in the worst eye said the optician on Monday.

Generally I wear contact lenses, old rigid style ones that are relatively cheap and reasonably durable. I still need specs though and my four year old ones are very scratched and the hinge is a bit wobbly so they need replacing.

I bought a lens hood for one of my Canon camera lenses last week. The one with Canon written on it cost 35€ which I thought was taking the mick. To be honest I was not that cock a hoop with 15€ price tag on unnamed version that I eventually bought.

Canon obviously charge for their name. Their RF 28-70mm F2L USM is a pretty good camera lens though even if it does cost 3,249€. For your money you get 19 elements packed in a sturdy barrel with all sorts of little motors built in as well as precision threads and what not. My arithmetic says that each element in that Canon lens, complete with their name on the barrel, costs 170€. The optician wants 240€ for each "mid range" lens. And 80€ for the plastic frame. 560€ for a pair of specs.

It's quite difficult to shop around amongst opticians. Spanish opticians aren't keen to give you their fitting information or prescription and even if they do the second optician always suggests that they can't trust the first's work. Obviously that changing lenses in that funny goggles thing and saying repeatedly - better? worse?, requires years of training.
