Top Five Trends in Outdoor Sunglasses

When you plan to buy sunglasses online, including designer prescription sunglasses also, pay more attention to the following 5 tips, please:
1.Changeable lens systems that allow the wearer to use dark lenses for sunshine, clear lenses for darker or in-the-woods conditions as well as simple protection from potential flying objects, or yellow and orange lenses for low light.
2.Lightweight and durable frame materials such as polyamide, which keeps its shape even under stress.
3.Styles that have both a performance advantage and sleek fashion styling.
4.Polarized lenses for glare reduction and better contrast, especially on the water.
5. Non-slip temple grips and nose pads, often made of rubber, that keep the sunglasses in place even in the heat of competition.
