I'm glad your eyes are ok Scrumpy. A few years ago I went blind in my right eye within an afternoon. I'd seen some floaters, and as I was walking home they multiplied until I couldn't see out of my eye at all. I rang 111 and they advised A&E, eventually it was checked, but it was Sunday night and there were no eye specialists there.
The next day I went to the opthalmic emergency dept and was referred to a consultant. I'd had a retinal bleed. No reason why, it just happened. It was scary, but he said it was operable. Long story short, it was repaired, I wore an eye patch while it mended, and I got my eyesight back. I was warned that a cataract was likely, and that too was eventually removed, leaving the vision in that eye better than ever. I've nothing but praise for the consultant, but it was a scary experience.
I've had lots of glasses from Specsavers, I like the two for one and the choice.
