   2 There are regulations in the U.S., but not every product needs to pass them, as far as I know. They are called the ANSI standards, and if a product passes them, they meet what the American government has set as standards. Check for them when buying sunglasses. Reply to this comment.

   5 I must agree with Jimi D. You should change the title. I don’t think that all cheap sunglasses are bad for the eyes. And how can you be sure Ray Bans or other big companies offer 100% protection? Because of the marketing or because of the prices? Reply to this comment.

   6 As Jimi says, the title is somewhat inaccurate. So is the article. Wearing sunglasses may well cause your pupils to dilate, but not to the extent that they let in more light than the pupils of someone who is not wearing sunglasses - if that were the case, nobody would wear sunglasses, because they would have the opposite of the required effect!

   7 LOL, so expensive sunglasses protect 0.5% of our body from UV light that *potentially* causes cancer. Phew. And here I was all worried since the other 99.5% of my body is still exposed. Off to go buy expensive sunglasses!! How did man survive before the age of sunglasses?! Reply to this comment.

   9 I have an idea! Quit asking the government to hold your hand in ever decision you make. The reason people make uninformed purchases such as buying sunglasses that increase your chances of cancer is because they assume that the government would never allow for an unsafe product to make it to the market. Take some responsibility for yourselves people and stop crying to the government. Reply to this comment.

    10 Rojash, you’ve missed the point. The glasses block the visible spectrum, your eyes dilate to compensate, but as you say, not to the point where they let more *visible* light in. They do however allow much more UV light in if the glasses are not blocking UV. Ergo, cheap non-UV blocking glasses are worse than no glasses at all. Reply to this comment.

    11 i saw a program on tv where cheap and expensive sunglass were tested for their 100% UV protection. The cheap sunglasses they tested did have 100% protection. Of course some sunglasses are novelties and i wouldn’t trust those. At least buy the ones that have a sticker on them claiming their protection. UV is not that expensive to manufacture. The conclusion of the story was that you cant trust any sunglasses unless you have them tested at an optometrist. Its on Youtube somewhere. Reply to this comment.

    14 UV light is blocked by most polymers like consumer plastic. That means you could wear any piece of clear plastic on your eyes clear like dollar store reading glasses and they would still block the UV waves just like a $500 pair of Gucci sunglasses would. The dark tint in sunglasses is just for polarizing the plane of the vis-light. Any piece of plastic will block UV light. This article is inaccurate. Reply to this comment.

    15 sensationalist title. cheap sunglasses don’t cause cancer, but they don’t help you block uv rays. causation is certainly different than a lack of a mitigating effect.. you had me thinking the cheap lenses somehow amplified the damage from the rays. Reply to this comment.

19. Macslut Posted: May 28th, 2008 at 4:43 pm

    19 rojash, What happens is that sunglasses block a percentage of light. Light is a spectrum composed of what we see and what we can’t see. Some of what we can’t see is damaging to our eyes. The issue mentioned in the article occurs when sunglasses block a large percentage of the visible light such that our pupils dilate, and then an even greater amount of the UV light (not visible) enters our eyes and causes damage. So here’s the real issue going on… With name brand sunglasses, they have a reputation to protect. When they sell $100+ sunglasses, they aren’t going to risk damaging their brand by skimping on a couple of bucks for true UV blocking lenses. Of course they could, it’s possible, but they are also a bigger target since it’s very easy to identify the name, model, retailer, etc… and ultimately the source. On the other hand, when you get glasses with no real name on them from a street vendor or wherever, and they got them from some drop-bulk shipment from China, there’s no brand or reputation to check, no easy way of tracking down the source, or tracking down where they all ended up being shipped or sold. And the original manufacturer of the glasses had no incentive to actually use UV blocking lenses. The manufacturer or anyone down the line could simply place the UV blocking stickers on the glasses. The US really should crack down on this. Reply to this comment.

    23 All glass-lens sunglasses block UV. In fact all glasses block UV. The only type of glass that will let UV through is quartz glass which isn’t used in this application. The fluid-like molecular structure of glass traps UV of all types. The only sunglasses that don’t block it are the ones with plastic lenses, which I can’t expect anyone would think offered any protection at all. This is just scaremongering. Reply to this comment.

    24 May I suggest a Title Correction. Cheep sunglasses do not limit the risks of cancer as well as expensive sunglasses. the article actually says that the cheap glasses cause pupil dilation and therefore an increased exposure to uv light, whilst I agree with there being a case for a title correction I disagree with jimi d’s title. “Cheap sun glasses may increase the risk of cancer” would probably be a better choice of title Reply to this comment.

    25 So people who don’t wear sunglasses will go blind and have cancer of the eyes? Has that been observed in the 4 billion people in China, India and Africa who, by custom, do not wear sun glasses? I don’t think so. Reply to this comment.

26. Doug Posted: May 28th, 2008 at 5:00 pm

    26 heh, I could tell this from a very young age. I could not wear non-polarized sun glasses. They make my eyes start feeling funny and eventually start hurting. This is back in the day when polarized sunglasses were pretty much a new thing. For years I could not get prescription sunglasses because they could not do polarized lenses. These days, expensive is not necessary. Polarized is. Reply to this comment.

    28 Rojash and Jimi, the author must have titled it that based on this line in the story: “This is bad for obvious reasons, but also because putting on sunglasses causes your eyes to dilate, letting more light in and in the case of sunglasses not offering UV protection, more UV rays as well.” Reply to this comment.

    30 very interesting. I’ve never heard of this - but thats an interesting point.

31. Bob Posted: May 28th, 2008 at 5:06 pm

    31 Simple answer if you are worried about your sunglasses. Take the suspect sunglasses to a glasses store like Lens Crafters etc and ask them to test them for UV protection. They have a device that emits and measures UV light. I buy my glasses from the guys in the mall $10 a pair, before I buy them I tell them I’m going down to the Glasses Store to have them measured. If they are not 100% UV blockers I’ll be back for a refund. I’ve never taken one pair back yet. Also you could buy your sunglasses in Canada, It’s against the law to sell sunglasses in Canada that do not block 100% of UVA and UVB rays. Both UVA and UVB need to be blocked. Blocking one or the other is useless and that goes for sunblock too. Reply to this comment.

    36 Maybe the title should be “Lack of government safety oversight leads to abuse”. Just saying, we in the U.S. are adverse to telling companies they can’t sell dangerous things to people, and even more unlikely to enforce some form of retribution when it happens. I hope we get over it soon. Reply to this comment.

38. Fafnir Posted: May 28th, 2008 at 5:31 pm

    38 Some people here seem to be missing the point… Sunglasses of any kind cause your pupils to dilate, because they block visible light. Therefore, sunglasses that do not block ultraviolet rays cause more ultraviolet light to enter your eyes than otherwise would. Exposing your eyes to ultraviolet light raises your risk of eye cancer. Hence, if you wear sunglasses that let ultraviolet rays through, you are more at risk of eye cancer than you are if you don’t wear sunglasses. This is not rocket science. Reply to this comment.

Take some responsibility for yourselves people and stop crying to the government. golly Jimmy, wonderful ‘conservative’ rhetoric. Just one question, without some government regulation how are we supposed to know what qua;lities/ingredients something has? I don’t have a UV testing lab in my car, so how do I know what standards the glasses have if there is not government oversight. And the only reason we get lists of ingredients and nutritional information - the things we need to be self-empowered consumers - is because of government regulations. We’re not asking gov. to make our decisions for us, just to ensure we have what we need to be able to make those decisions for ourselves. Reply to this comment.

    40 Bob-31 is one of the few that is HELPFUL as well as being more right. Most every glass and polymer (plastic) blocks most ultraviolet light. I recently had to search very hard to find glass windows for a house addition that specifically LET UV light in (when not overdone, UV helps body generate Vitamin D). This article simply explains the concept that thought the human iris contracts and restricts ALL light, glasses that restrict visible light only while letting through UV light (rare) effectively FOOL the eye in a potentially dangerous way in that the UV amount is still high while the iris is made WIDER than normal.

The only sunglasses that don’t block it are the ones with plastic lenses, which I can’t expect anyone would think offered any protection at all. Be careful: this is wrong. The UV transmission of glass is somewhat variable, while the UV transmission of all transparent plastic sunglass lenses I’ve ever seen tested is quite close to zero. Expensive sunglasses with glass lenses may be somewhat UV transmissive (as well as being shatter-prone). As someone suggested, if you have doubts about the UV protection of your sunglasses, take them to an optical shop and have them tested. http://www.newton.dep.anl.gov/askasci/chem00/chem00539.htm http://www.astm.org/DIGITAL_LIBRARY/STP/PAGES/STP18176S.htm http://en.wikipedia.org/wiki/Fused_quartz Reply to this comment.

    46 My brother use to work for an optical instrament company. They have a machine to check light spectrum among other things. As a fun experiment, they place different sunglass in the machine. The conclusion: It was surprising. Cheap sunglass actually blocked more UV than expensive ones. Cheap plastic glass don’t transmit light that well, so they don’t transmit UV as well. Expensive glass on the other hand are so clear that they pass more light as well as UV light. We are talking about small amounts here because the machine is very sensitive. If you want to protect your eyes better, skip the RayBan and get the cheap $10 ones. Reply to this comment.

    52 It’s bullshit that anyone should be relying on the government to mandate something. That’s what’s gotten us in so much trouble with our economy. The only way to ‘mandate’ something like this effectively without backlash is to let capitalism run it’s course. If we go to private organisations (eg. Good Housekeeping) and look for their stamp of approval, the bad sunglasses will be forced to raise their standards or be forced out of the market. The answer to any question of government mandation is FUCK NO! We the people need to fucking do it ourselves. Also, as an Australian I dispute that there is a “massive” population.

See link: http://www.squaremouth.com/travel-advice/cheap-sunglasses-and-the-naked-eye/ Here’s a quote: The cheapest pair of sunglasses–and even clear glass or plastic, for that matter–can block a significant amount of UV radiation. “You’re just not going to get in trouble if you block out sunlight,” says Dr. Kent Daum, an associate professor in the School of Optometry at the University of Alabama at Birmingham.
