Hi All
Just to fill you all in on uv protection, being an optician its my area. As long as the sunglasses are marked with ce they will conform to all the uv requirements. All sunglasses in this country should leagally have a ce mark weather they are 99p or £90. Some of the expensive designer brands will offer a better level of glare protection than others, but how much glare protection needed is more of a personal preferance and will probably depend on your eye colour, lighter iris's will tend to be more photphobic, (light sensitive). Rayban lenses are fantastic, but be careful as most are glass lenses and will shatter if dropped on something hard or if you have an accident in the car. I tend to use a polorised lens as this is one of the best glare protection lenses for driving, it cuts down reflections on water ect, so brill for looking in the sea at fishes ect.
So dont feel you are putting your eyes at risk for buying cheaper styles just check for the ce mark, and make sure you look cool of course!!!
