I've used them for an eye test too - I had a free eye test offered with lots and lots of Nectar points, and as I hadn't had one done for about twenty years, I thought, better had.
Of course, eye tests have completely changed in that time, so I had no idea how they compare - now, with a bit more experience, I think they compare very well indeed. I was seen by three members of staff, who took me through various parts of the testing programme, and I was also given feedback on what each test was for and what my results were, not just a quick summary at the end.
I was given a prescription at the end, but wasn't pressured to take it out or buy expensive frames. And with it being so central, its a quick option in any case for most people, just about fits into a lunchtime.
Thoroughly recommended. read more
