this is stupid but where can I get not too expensive sunglasses, that are not completely unfashionable/ugly and actually protect my eyes (in uk shops)! I normally buy them from Topshop or somewhere but they are ok for the UK weather but no where sunnier really!
Just make sure that they are 100% UV resistant (UVA and UVB) and you'll be alright. As long as that's good, then the darkness or colour of the lens is just personal preference, but your eyes will still be protected from the harmful rays.
Thanks for the advice moutallica
