Not really. wearing cycling sunglasses are not just for looking cool, the sunglasses can do something good to eyes. In details, with cycling sunglasses, they can block UV rays, prevent wind and debris, and filter glares so that to provide you comfortable vision when you biking. For people with poor vision, they can buy prescription cycling sunglasses for both eye protection and vision correction. So, cycling sunglasses are necessary to people like cycling.

People wear cycling sunglasses not just for cool. The main purpose that they wear cycling sunglasses is for eye protection. When people ride on the road, the strong wind will get into the eyes, which make your eyes hard to open. In addition, the dust and some particles can easily get into eyes, thus your vision will be affected. While wearing cycling sunglasses can not only protect eyes from the wind, dust and particles, but also from UV rays which can cause damage to eyes after long-term exposure to the sun.

Basically speaking, non-sportsmen wear cycling sunglasses for fashion because you don't have some know-hows of cycling sunglasses. The incentive of buying such glasses is their advanced design. But for the athletes who carry out cycling, the cycling sunglasses are their indispensable eyewears because they can efficiently prevent the blinding sunlight and help them to go on the activities without any interference.
