Since you’ll be spending time outdoors this summer, you want to make sure your eyes are protected from the harmful ultraviolet (UV) rays. It all starts with the sunglasses that you wear before heading out. Here’s how you can tell if your pair of spectacles are truly protecting your eyes from UV damage.
If your pair of sunglasses are the wrap-around type, you can be sure that they can protect your eyes from UV rays coming in from the side. The configuration of these spectacles also keeps the wind from drying your eyes out while you’re outside.
UV 400 Protection
Check the label of the sunglasses you purchased and look up the term UV 400. It indicates that the lenses block light rays with wavelengths of up to 400 nanometers. These include UVA and UVB rays, which are known to contribute to a wide range of UV-related risks. These include cataracts, macular degeneration and ocular melanoma, which is a rare type of cancer.
Although it’s not everyone’s style, it’s been proven that sunglasses with larger lenses provide better protection for your eyes. This is because they create better coverage for your face and protect your eyes from UV rays reaching from all angles.
About Dark-Tinted Sunglasses
Just because your sunglasses have dark lenses doesn’t mean they block harmful UV rays. In fact, putting them on causes your pupils to dilate, allowing more light to enter your eyes than if you don’t wear sunglasses at all. What they do is filter out ambient light and glare – nothing more. If you prefer wearing sunglasses with darker or heavily tinted lenses, you can ask your eye doctor for options that provide UV 400 protection.
