I went to get some new specs. today. I had my eyes tested at Vision Express, I'm badly long sighted ( +5) so I always opt. for the thinnest lens possible. V/E offer a lens with a 1.74 index, but I was put off by the price: £291. This cost is in addition to the frames!!
I called into Costco on my way home and was staggered. The price of their 1.74 index lens is £119. And the frames are considerably cheaper there too. That's some saving.
I know you have to be a member (or know a member to get in, but you must know someone?).
Thought someone else might also be able to benefit???
