Details

Many friends do not know what type of sunglasses they need when buying sunglasses. They just pay attention to the ranking of sunglasses brands and follow their own preferences. After all, sunglasses are for eyes. People need to protect their eyes more, so they should know more when choosing sunglasses to reduce blindness. Do you know the type of sunglasses? Now let Wenzhou Wanrun Glasses Factory give you a detailed introduction of sunglasses.

Sunglasses can be roughly divided into the following types: anti reflection protective lens This lens can prevent strong light reflection, so that you can see things in strong light without interference, and see more clearly. The principle of this lens is very simple. The surface is coated with magnesium fluoride. If you want to know whether your sunglasses are anti reflection protective lenses, when you see purple or green, you can aim your glasses at the light source, which means that there is an anti reflection protective film on the lens.

Colored lens: This lens is also called "tinted lens". Sunglasses using such lenses can absorb light of specific wavelengths. The principle is to add some chemicals to make the lens appear color. This kind of lens is the most commonly used lens for sunglasses. In fact, the effect of the painted lens is the same as that of the color lens, but this lens is usually used for sunglasses with certain strength. The common way is to "gradually change" the color from top to bottom, from deep to light.

Polarization lens: The word polarized light is widely used in sunglasses, but many people do not understand its specific meaning. In fact, this kind of lens is used to filter out the lines of glare from the sun and other directions, and special coating is added to the vertical direction of the lens. It is very suitable for outdoor sports (such as sea activities, skiing or fishing). Color change through, another name is "sensitive lens". The originally transparent and colorless lenses will become colored lenses to protect the eyes under strong light. This is because silver halide chemicals are added to the lens, so it is suitable for both indoor and outdoor use. The article comes from the network.
