Is Polarized glasses anti -ultraviolet rays?

Polarized mirrors can prevent ultraviolet rays, but the protection capacity is weak.

The primary function of polarizing Sunglasses is to prevent ultraviolet rays and filtrate polarized light. Good polarized Sunglasses lenses can block more than 90%of ultraviolet rays.UV prevention effects with polarized Sunglasses with "UV400" are the best effect.

The polarizing mirror is a lens manufactured according to the polarization principle of light. It can exclude and filter the scattered light in the beam, and anti -ultraviolet rays and filtration polarized light.A good polarizing mirror can achieve the color of the surrounding environment, the edges of the object are clear, can effectively identify different color signal Lights, and reduce the ultraviolet rays that are irradiated into pupils.

The Polarized mirror is better than the shutters, but it only blocked some light, and the light (including ultraviolet rays) that is basically parallel to the polarization angle of the polarization is still released. From the perspective of protection, it is equivalent to adding a layer of soft gauze to the window., It's just partially blocked.The biggest advantage of polarizing mirror is to block the glare interference and make the visual effect more clear, and the protection of ultraviolet rays is not as good as reflective Sunglasses and color transformer mirrors.

How to judge whether polarizing Sunglasses have anti -ultraviolet function

1. Look at the label

Obvious signs such as "UV" and "UV400" are seen on Sunglasses labels or lenses on UV prevention.The "UV Index" is also the effect of filtering from ultraviolet rays. This is a very important standard for buying Sunglasses.The light of the wavelength at 286nm-400nm is called ultraviolet rays. Generally speaking, 100%UV index is impossible. Most Sunglasses of the UV index are between 96%and 98%.

There are Sunglasses with anti -ultraviolet function, generally there are several clear ways:

(1) Mark the "UV400": This means that the lens cuts the wavelength of ultraviolet is 400nm, that is, the maximum value of the maximum value of the spectral ratio of less than 400nm in the wavelength () is not greater than 2%.

(2) Mark the "UV" and "UV": This means that the lens's deadline for UV is 380nm, that is, the maximum value of the maximum value of the spectral ratio of the spectral ratio below 380nm below 380nm is not more than 2%.

(3) Mark "100%UV absorption": This means that the lens has a 100%absorption function on ultraviolet rays, that is, its average transmission ratio in the ultraviolet interval is not more than 0.5%.

The Sunglasses that meet the above requirements are Sunglasses that truly have protection for ultraviolet rays.

2. Use banknotes to verify

In the absence of instruments, ordinary people can also detect whether Sunglasses have the function of anti -ultraviolet rays.Take a banknote, put the Sunglasses lens on the anti -counterfeiting watermark, and use the banknote pen or the banknote inspection machine to take a look at the lens.This pair of sun mirrors is anti -ultraviolet.
