The color of sunglasses is an important factor in the protection, or lack of it, that these furnish against ultraviolet and infrared radiation. Sunglasses that are tinted gray are believed to give the highest protection. Almost as good are those tinted brown or green. But sunglasses tinted blue or purple can be dangerous. Said Science Digest: “Blue or purple sunglasses can expose you to more ultraviolet radiation than no sunglasses at all! That happens because a dark lens causes your pupils to dilate, which means blue or purple sunglasses inflict ultraviolet rays on your eyes after ‘tricking’ them into lowering their defenses against sunlight.”
When shopping for sunglasses, it is always important to check the label or tag to see if the sunglasses are rated to provide full protection from UVA and UVB light. Even though you may pay a little more for such protection, it is well worth the cost compared to the damage that can happen to the eyes, cataract surgery, or, even worse, blindness. You owe it to your eyes to seek the best protection possible!
