Sunglasses with Suntan Concave Design
Nowadays, almost everyone has learned the concave shape of sunglasses. Whether it's in the mall, on the street, or at the airport, you can see many people wearing concave shapes of sunglasses. But can all sunglasses have a concave shape?
Many people say that sunglasses only need to look good, or as long as they are popular; Many people also say that sunglasses are just good for shading and preventing ultraviolet rays. Is that really the case? Do you really have no requirements for sunglasses?
Generally speaking, the style of sunglasses is fine as long as you like it and it doesn't look too bad! What needs to be noted is the color selection of sunglasses. The color selection should not only be based on personal preferences, but should be chosen according to one's own situation. So, let's first understand the functions of various shades of sunglasses:
1. Gray, gray lenses can absorb any color evenly, allowing you to see things without color difference, giving you a true and natural feeling.
2. Brown, brown can filter out a large amount of blue light, while also improving the contrast and clarity of our vision.
3. Green, we all know that our eyes prefer green, and wearing green lenses can make people feel particularly cool and comfortable.
4. Blue, the darker the color of the blue lens, the higher the visible light absorption rate.
5. The surface of water silver lenses mostly adopts high-density coating technology, which can effectively absorb and reflect visible light.
The color depth of sunglasses is divided into four levels according to the absorbance of visible light. They are: visible light absorption rate of 15%, visible light absorption rate of 34%, visible light absorption rate of 50%, and visible light absorption rate of 70%. Different levels have different uses, such as sunglasses with a visible light absorption rate of 15%, which are more suitable for frequent indoor and outdoor wear, especially for people with myopia. Sunglasses with a visible light absorption rate of 34% are suitable for wearing in ordinary sunlight; Sunglasses with a visible light absorption rate of 50% are suitable for wearing on the scorching seaside; Sunglasses with a visible light absorption rate of 70% are generally only suitable for engineering workers such as welding.
Therefore, when choosing sunglasses, it is best to be able to choose according to the purpose, otherwise the color may be too light or too dark. Because colors that are too light cannot effectively block sunlight, and colors that are too dark can affect your visual transmission and become dull.
