In summer, sunglasses are standard for travel. Many people focus on style and color when choosing sunglasses, rather than choosing based on function and needs. As everyone knows, different colors of sunglasses have different functions.So, in the face of colorful sunglasses, how should we choose?Gray - Gray lenses are the most common, they can absorb most of the color spectrum evenly, there will be no obvious chromatic aberration when viewing the scene, and they will not change the color of the vision, which is suitable for most people.Brown-Brown lenses can filter a lot of blue light, improve visual contrast and clarity. It can see details of objects even in harsh light, and wear better in air pollution and foggy conditions.Green - Green lenses can increase the green light reaching the eyes, making the wearer feel cool and comfortable, suitable for people who are prone to eye fatigue.Silver - Silver mercury lenses can absorb and reflect more solar radiation, suitable for outdoor activities with better sunlight.Red and blue - red and blue lenses are not good for eye protection, red is poor in blocking light, and blue lenses promote blue light to stimulate the eyeballs, so it is not recommended for everyone to choose, but they can be used as decoration.In addition, remind everyone that the size of the sunglasses can at least block the visual imaging area in front of the eyes, and it is not appropriate to choose too small and too large sunglasses. If you choose sunglasses that are too small, bright light can easily irritate your eyes. Choosing oversized sunglasses will put a burden on the bridge of the nose, and people with smaller nasal bones are prone to slipping off. Just click  https://sunglassesoffers.com/category/womens/
