1. UV protection: lenses that are darkly tinted do not inherently block ultraviolet rays. UV protection should be built into the lens. Purchasing from a reputable company known for their lenses ensures quality. The free happy meal sunglasses may not have the protection your eyes need! Although sunglasses are regulated by the FDA as a Class 1 medical device, they are loosely regulated; therefore it is difficult to simply trust the stickers on the lenses that say “100% UV Block.”
2. Impact resistance: activities that we do when wearing sunglasses often involve more risk to the eye. Impact resistance is a quality of the lens materials that are used in most name brands, but may not be a quality of a nameless brand. Impact resistance also comes from the frame material and design. If the frame is safety rated, it is designed so that the lenses cannot easily be pushed through the frame into your eye. Some brands have break away temples so that in a crash, the temple does not poke your eye. Most sport frames are made of a durable and flexible type of plastic.
3. Good coverage of the orbit area from the sides. This is why good sunglasses are either large or wrapped. Many sport sunglasses are made to be wind-resistant as well.
4. Ability to accommodate your prescription. Many people are unaware they can get their full prescription in sunglasses. We live in sunny southern California, and it is a necessity to see! Many of the sport brands have options for making your prescription in the lens. Depending on your prescription, the lens may be made in an authentic branded lens, even with a progressive. In some cases, an “Rx carrier” may be used to provide your prescription.
5. Tints and features that compliment your vision for your particular sport or outdoor activities. There are frames that do not bounce when you run, have sweat channels and cooling features so they do not fog, float for use on the water!
