Got ‘convinced’ that I needed to ‘upgrade’ to varifocals at my last eye test (I have worn reading glasses for a few years now) which would help with my intermediate range vision (watching TV). I opted for the custom made lenses as they were supposed to have a wider sweet spot and less distortion at the edges.
Could not get on with them – the distortion made me feel sick and the reading area was so hard to find it drove me up the wall. I tried to wear them for driving but I felt they were more dangerous wearing them than the slight improvement they produced.
Thankfully I got a full refund on the cost and have stuck with my current glasses…
