I never pay more than £6 for sunglasses. It's true that they keep breaking, but optically I can't tell the difference. When I do lose them (as two years ago they got washed away in the sea when I forgot I had them on my head), they need not to have been expensive.

Cheap sunglasses are worse than useless.
The eye has its own protection from UV rays causing damage; the iris gets smaller letting less light into the eye.
Cheap glasses without UV resistant lenses simply make the iris open wider to compensate for the reduced light available at the eye due to the dark tint of the glass.
The result is more UV gets in to cook the retina.

I bought a pair of sunglasses last week - Oliver Peoples with prescription polarised lenses, high-density too - I should be picking them up end of the week and they cost a ...a lot. Really a lot.
But they will last a very long time and as Hyper says all covered by the insurance. That's what I keep telling myself.

That's all correct, Pete, but what do you think it takes for glasses to be UV resistant?
