Sports sunglasses are designed to protect your eyes while you're participating in various athletic activities. They typically feature lenses that are made from polycarbonate, which is a type of plastic that is highly impact-resistant. This is important because it helps to protect your eyes from flying debris or other hazards that you might encounter while participating in sports or other activities.
In addition to being impact-resistant, the lenses in
sports sunglasses are also often polarized, which helps to reduce glare and improve visibility. They also often have a UV filter to protect your eyes from the harmful rays of the sun.
