Blocks peripheral light
Ombraz sunglasses are great for sports or anything in general that makes sunglasses fall off your face. It's also lightweight and more comfortable than most sunglasses. The one downside is that the lenses don't come with anti-reflective coating. Perhaps in the future it will but with the Side Shields recently released there's really no need for anti reflective coating. It blocks light from the sides so no harmful UV rays can reflect from the lens into your eyes. Also helps protect your eyes from dust. The shileds are ventilated for breathability.
