Avoid buying sunnies from Bali etc. They do not meet australian standards, and are often worse for your eyes.
They cause your pupil to dilate (get bigger) and allows more light in. But the lense only makes it darker, doesnt stop the uv rays etc. Your eyes will get more rooted due to more uv than normal getting through.
Not sure about polarised sunnies being different. But if you buy in austalia (even kmart etc) they have to by law pass the same standards. I got my kiting sunnies from bigw. Polarised for 30 bucks. Got a little rope thing to hold em on. If i lose the lot im down $45. No biggie. Id rather look like a tosser, than not be able to look at all.
This and the previous posts on protecting eyes from uv rays all show the effect of marketing on our perceptions.
I had corrective laser eye surgery a few weeks ago (...wooo hoo no more specs...) and the eye surgeon told me that everything you hear about what type of uv block out your sunnies provide is all crap.
A simple clear lens, ie bit of glass, like normal prescription glasses, will block out 99% of any harmful uv rays.
She said there is absolutely no difference, in terms of protection of the eyes from uv, if you buy a cheap $20 pair of sunnies, or a $250 pair.
Who do you believe, an eye surgeon or a sunglasses retailer?
I don't know what the Australian standard for eye wear relates to??
