Are Polarized Sunglasses of Great Use Besides Being Cool?
Polarizers can also be considered a category of sunglasses, but they are a relatively high-end category among sunglasses. Polarizers have a function that ordinary sunglasses do not have, which is to effectively block and filter out various harmful polarized light to the eyes.
The so-called polarized light refers to the irregular reflected light generated by light passing through uneven roads, water surfaces, and other places, also known as glare. When these rays of light directly illuminate a person's eyes, they can cause discomfort and fatigue, and cannot sustain vision. The clarity of the object being viewed is also significantly insufficient.
Generally, sunglasses only use the function of reducing light, because ordinary lenses cannot filter light, so they can only reduce the intensity of glare, ultraviolet light, and other harmful rays, and cannot completely block them. Therefore, their function is only to reduce eye damage. However, the biggest advantage of sunglasses is their good popularity. Polarizing lenses, due to their polarizing properties, can completely block glare caused by various factors such as scattering, refraction, and reflection. At the same time, it can also completely block harmful ultraviolet light from the human eye, making the eyes less prone to fatigue during long-term activities under strong light, achieving a truly protective function, and making what is seen clearer and more three-dimensional.
Polarized sunglasses, due to their ability to polarize light, can block all harmful light without affecting the transmission of visible light, truly achieving the function of protecting the eyes. Polarized sunglasses not only have basic UV protection functions, but also have anti glare, reflected light on the road surface, and scale light on the water surface, making them suitable for driving, fishing, tourism, and daily wear.
