Yes. Some sunglasses at drugstores have a decal that claims 100% UV (ultra-violet) protection. In reality, they have 100% of the FDA minimum recommended UV protection, which amounts to only 70% UV protection. This is deceptive, but legal, unfortunately. The problem lies in the fact that UV light is known to contribute to cataract formation and macular degeneration, and therefore it is important to block 100% of these harmful rays. We should buy sunglasses is to protect our eyes 100%. Of course, fashion is important today as well, but saving a few dollars on drugstore sunglasses may cost you serious vision problems in the long run. Drugstore sunglasses typically lack in optical quality. Cheap lenses cause distortion, possibly decreasing the clarity of your vision, or at least causing eyestrain. If you have ever worn cheap sunglasses and had to remove them and rub your eyes, chances are youve experienced poor quality-induced distortion. Patients will claim they are too careless with their sunglasses to invest in a nice pair. We tell our patients that if they invest in a quality pair of sunglasses, they are much more durable, and when they appreciate the quality, they will happily take care of them. Think of your sunglasses as a vision-saving device, and not just a fashion accessory.
