Yeah, my optician keeps telling me to come back for a contact lens appointment - not sure these days as my eyes are drier than they used to be.
Consider trial of multifoca l contact lenses. ;)
I only give things to charity which I think are still usable - handed in a load of spectacles/sunnies I'd bought over the years from Goggles4U and Zenni to the British Heart Foundation* a few weeks ago, some not worn that often as I tend to stick to a few favourites. Internet specs are good way to experiment, I suppose. The popularity of those sites means that the quality/looks of second-hand prescription glasses will be much better than the dreaded days of "NHS Specs" kids got bullied at school for. I'm now on varifocals as I had contact lenses in a year or so ago and *couldn't read the menu* in a restaurant at all..close up sight is getting worse :( *Weirdly, their website says they don't accept prescription spectacles, yet the shop I visited took them quite happily.
I have always recycled glasses through charities, but recently read this interesting piece - excerpt copied below. https://www.theguardian.com/news/2018/may/10/the-invisible-power-of-big-glasses-eyewear-industry-essilor-luxottica I can understand the reasoning but it saddens me that image and branding has taken hold so completely. It also contradicts my own observations regarding clothing in some of the poorest countries in Africa, where you do still see people wearing clothing which seems to me to be beyond branding. Perhaps the few countries which still don't care about branding haven't yet reached the stage of providing optical care. I certainly don't recall seeing glasses being worn, and will be sure to take more notice on my next trip. "The fusion of the fashion industry and the optical business is now regarded as complete. Until recently, eye-health charities and campaigners used to distribute thousands of pairs of secondhand glasses from richer countries to poorer populations that lacked them. In 2011, the World Health Organization advised them to stop – in part because people were refusing to wear outdated styles. “Being poor doesn’t mean we want to look stupid, you know,” Prof Kovin Naidoo, who runs the Brien Holden Institute, one of the world’s leading eye-health NGOs, told me."
I should imagine they do as opticians you can pop in and they'll do it for free, screw and fix for you.
