Prescription Sunglasses

Iris optical do free lenses. If your perscription is under +/- 3.00 they'd be not too thick. Otherwise it's £50 for thinner lenses

Got a good selection of Frames. They don't do eye tests though, you take your perscription to them.

I always take an attractive girl along. Not so much because I value the opinion, just that at some stage she might say "yeah, you look really good in those" and it will feel nice.

This adds to the problem. Where do you get an attractive girl?
