The difference between sunglasses and polarized lenses

u003cbru003eTo talk about polarized lenses and sunglasses, we must first introduce some knowledge about polarized lenses and sunglasses. In fact, polarizers are considered to be a category of sunglasses, but polarizers belong to the more high-end category of sunglasses. Polarizers have an effect that ordinary sunglasses do not have. This effect is to effectively block and filter out all kinds of polarized light harmful to the eyes. Recommended reading: How to maintain polarized sunglasses. The so-called polarized light is the irregular reflected light produced when light passes through uneven roads, water surfaces, etc., also called glare. When these rays of light irradiate human eyes directly, it will cause discomfort and fatigue in human eyes, and cannot see objects for a long time, and the sharpness of the objects seen is obviously insufficient. The polarizer uses the linear molecular arrangement inside its lens to filter and eliminate all kinds of glare that damage the eyes. That is, the polarizer passes through the linear molecular arrangement in the lens to reflect irregular reflections. The light was sorted out again, and the light in the eyes became clearer and more natural. 1 The difference between polarized lenses and sunglasses So where is the difference between polarized lenses and sunglasses? First of all, polarizers and general sunglasses have the function of preventing ultraviolet rays and reducing the intensity of light, but general sunglasses do not have the function of blocking or converting polarized light. This is the difference between polarized lenses and sunglasses. Therefore, the price of general sunglasses is relatively cheaper than polarized sunglasses. 2 The main purpose of the polarizer The main purpose of the polarizer is to protect the eyes from damage under certain conditions. But for those who are not very demanding, ordinary sunglasses are fine, because polarized sunglasses are relatively high-end sunglasses. Of course, if you are a car owner, it is best to wear polarized sunglasses when driving, because driving often encounters various glare, polarized sunglasses can block part of the glare, but also filter out the ground or The strong light reflected from the opposite car body makes the vision clearer, reduces visual fatigue, and is conducive to safe driving. -The viewing angle effect of the polarized lens is more natural and clear than that of sunglasses. In addition, it is also more suitable to wear a polarized lens when doing outdoor sports such as fishing, skiing, and vacation. 3. The difference between polarized lenses and ordinary sunglasses. In fact, the difference between polarized lenses and sunglasses and the way to distinguish them are relatively simple. As long as the two polarized lenses are stacked vertically, if they do not transmit light, it is a real polarizer. Because the special design of the polarized lens only allows parallel light to pass through the lens, when the two lenses are stacked vertically, most of the light Will be blocked. In addition, you can go to the bottom of the sun for a specific experience. In the sun, polarized lenses are significantly more comfortable than ordinary sunglasses. Of course, the difference between polarizers and sunglasses is also clearly reflected in the price. At present, the price of general polarizers on the market is around a few hundred yuan, while professional outdoor polarizers range from thousands to tens of thousands.
