i always use Direct Dpecs, you will need to take your eye prescription with you, dont ever feel forced to buy from the usual optician shops just because you have your eyes tested there, you pay for the test anyway but youre not obliged to have their products, some are a rip off in my opinion. i usually pay approx �50 for a pair of glasses for distance or the same for a pair of prescription sunglasses. Not sure if Direct Specs are nationwide, will depend where you are i suppose.
