Running in the sunshine is wonderful, but if you don't have the right eyewear, you'll spend the whole time squinting and blinking (not to mention possibly damaging your eyes). Not all sunglasses are alike — specifically when it comes to running. The best running sunglasses require special features that you wouldn't necessarily need when you're lying on the beach or strolling through town.
First of all, they need to stay put. One of the biggest problems when you're running in sunglasses is that they tend to flop around or slide down your nose. When using them for athletics, you need sunglasses that are extra snug and secure.
Your running sunglasses also need to be extra durable, because they often taking a beating. They get exposed to dirt, dust, and other elements; plus, you sweat in them, so they get exposed to moisture, too. Materials such as polycarbonate and other tough plastics will be your best bet.
Lastly, you need exceptional visual clarity. Although it's always nice to be able to see clearly, when you're running it can be a matter of safety. On trails, you need to be able to see the terrain, and on roads, you need to be able to watch out for traffic. High-quality lens technology is essential in running sunglasses.
There are tons of options out there, so to help you make a decision, I've rounded up a list of the best running sunglasses with these factors in mind. I've tried several of these out myself, so I can personally vouch for their awesomeness on the road.
