Fantastically helpful for my very high prescription. My new glasses are I think the best I have ever had ! The lenses must be very good quality as they give really sharp clear vision. The prescription was for reading but I have found that by pushing them really close I can see distance as well. I just let them slip down a bit for reading. I understand that GFL asked the suppliers to re-make the lenses as the first ones were thicker than they needed to be. As my prescription is +33 I am grateful for anything that improves their appearance. I seem to have a much wider field of vision through the new glasses. Although I wear contacts most I inadvertently drove down to the shops while still wearing my glasses. I did not realise what I had done till I got back home and it just goes to show how good the glasses are. I will have to make sure I don't do it again. Thanks for all the help to everyone at GFL,
