I live in a tropical climate and I have sensitive eyes and still very good eyesight. And I also break sunglasses like nobody's business. So I don't want to spend hundreds for namebrand sunglasses which are probably still made in China. Would you dare use any of these claimed "Polarized / UV protection" shades from DX?
Personaly i would not. Not a huge fan of big brands but i wear a Oakley model of sunglasses for the same reasons you do. They re doing still fine after 5 years of abuse. I would reccomend you search for the Adidas brand. They made some good looking sunglasses with very decent lenses for not much of a price.
Hmmm, yes, you're absolutely right Budgeteer. But I just sort of doubt the protection claims on ANY sunglasses. I've been using cheap ~$12 sunglasses from department stores in the United States, but they're not readily available where I live. They have served me fairly well so far, seeing as I always sit on them or drop them or lose them.
Apparently the polycarbonate they usually make sunglass lenses out of inherently blocks UV so it shouldn't be too dangerous.
However, an important point is fit, so you're better off trying on a cheap but decent one at a physical store.
With the polarisation, you can test them with another set of polarised lenses by rotating them and seeing if it changes. Considering that budget sites can sell polarising camera filters for under ten bucks, it isn't too hard to believe that they're really polarising.
I've broken several Maui Jim's and felt like crap each time so I might just buy a couple of these el cheapo's. Any eye protection is better than none. 8)
An eye doctor once told me "If you are going to wear cheap sunglasses, it is better not to wear at all. If you wear sunglasses, your eyes relax and open up feeling protected but - in case of low quality sunglasses - they are not and can be damaged. If you don't wear sunglasses at all, your eyes try and succeed protecting themselves".
So, for me, good quality sunglasses which block UVA/UVB (and this can be measured at optics stores).
My friend bought some fake brand name glasses from ebay and when he got them, he went straight to optical store where they checked/measured UV protection. Indeed they had very good UV protection. The guy working there explained to him that the main difference between brand name and the fake ones are in brightness and contrast. Fake ones block UV light, but also block a lot of light that really isnt harmfull (so you get much darker image with worse contrast), but brand name ones can give you better contrast with also good UV protection!
I have very sensitive (blue!) eyes - it takes quite a long time for my eyes to adjust to bright sun light, so I really dont mind the darker sun glasses...
I personally would never trust my vision to sunglasses sold by a site that is world famous for lies about its product specifications. Please dont make this mistake. UV protection is very important. Under the right conditions, it doesnt take long to permanently damge your sight from a lack of proper UV protection. Google is your friend if you need to learn more.
Quite interesting. I was always afraid that cheap optics would make you lose sight with time cause being the stress on the eyes to adjust the focal distance distorted by lower quality lenses. UV filter should not be a problem.
Will check if they're UV-Protected, but I am confident they are. AFAIK, plastics as thick as in sunglasses will stop 95%-100% of harmful UV even without coating. We will see.
If someone finds a reasonably priced shop with more Oakeys, please say so!
My eye doctor told me the same thing, I'm pretty convinced he was just trying to sell me on the value of the lines he sold as opposed to me going elsewhere to buy less expensive sunglasses-which I did anyways.
