Sunglasses are not only worn for beauty, but also given more meaning, which can prevent ultraviolet radiation and better care for eye skin. Then this requires us to choose sunglasses more harshly. Generally speaking, the sunglasses in street stalls can't meet the standard of ultraviolet protection. Therefore, it is suggested that you go to a regular optical shop to buy sunglasses with anti-ultraviolet effect, so as to better care for eye skin.

When we choose sunglasses, the choice of lenses is more critical. Every detail needs careful observation, depending on whether the lens surface is fine and smooth enough. The whole lens has no ripples, no flaws, no bubbles and even no wear marks. These small flaws will affect the wearing of sunglasses, so when we choose sunglasses, we need to make the lenses square. Observe whether the lens is curled or uneven in horizontal direction. If the lens has bumps, bubbles and wear marks, don't choose it.
03, the lens color should be more realistic and undistorted, and the signal lights of different colors can be accurately judged.
Sunglasses are all colored. After wearing clothes of different colors, you will see different colors of the surrounding environment. When we choose sunglasses, the color of sunglasses should not be distorted. If the color you see deviates too much from the original color, even the edge of the object is not clear, it will affect our overall ability to observe things. When choosing sunglasses, we must be able to judge the signal lights of different colors, otherwise the sunglasses with distorted colors will really affect our safety.
In addition, when we choose sunglasses, we need to refer to our face shape, the size of our eyes, the distance between our five senses and so on. Sunglasses that match your facial features will be more beautiful to wear. At the same time, wearing the right sunglasses can also be more fashionable and show a small face. When choosing sunglasses, you can also try different frames to find the style that suits you best.
