Not really good deal for everyone, but a GREAT one for those with high prescription glasses... ASDA are doing frames with whatever lenses you need, 1 pair for £50, 2 pairs for £90! No paying extra for thinner lenses.
Vision Express charge £180 just for the thinner 1.74 plastic lenses alone. ASDA will do frames + lenses for £50!
Just been to Asda (with my prescription of -8 in one eye, -9 in other) and got 2 pairs of designer (1 bench, 1 nike) frames + lenses for £90, one with 1.74 plastic lenses and other with 1.91 glass lenses!! With my NHS voucher, that works out at cheaper than £40 per pair of glasses with the thinnest lenses available...
That hands down beats even all the internet only places like goggles4u! BARGAIN!
