In the hot summer, many people wear sunglasses. Sunglasses are essential for eye protection. Many optical shops and jewelry stores sell sunglasses in various styles and with unique and fashionable colors. They are very eye-catching and really make people dazzled. Here I would like to remind all the beauty lovers that sun lenses of different colors and materials have different characteristics, so you should be careful when purchasing. Strong sunlight contains a lot of ultraviolet and infrared rays. If you don't pay attention to protecting your eyes and go out without wearing sunglasses, it is easy to cause damage to your eyes. The difference between different color lenses: Gray lenses can absorb infrared rays and 98% of ultraviolet rays, allowing for more natural vision. They basically do not change the original color of the scenery and do not cause distortion, making them very suitable for travel. Moreover, the gray lenses also have anti-glare function, and wearing them while driving can effectively improve the driving safety index. Another common color is brown lenses, which can be said to be the most popular color in sunglasses and is a general color. Brown lenses can almost perfectly absorb 100% of ultraviolet rays and infrared rays, and the visual effect is also better. When worn, the wearer can feel that the tones of the objects they see are soft and comfortable, and will not cause visual fatigue. Some people in the market now maliciously exaggerate the role of crystal lenses, which is actually unscientific. Crystal lenses cannot block infrared and ultraviolet rays. Even colored crystal lenses are far inferior to glass lenses in performance. When buying sunglasses, you should choose according to your personal living environment and the nature of your work. If you only wear them as decorations, you should also pay attention to the occasion when you wear them. |
