What do you mean by polarised sunglasses?


     Due to the rapid development of the eyewear world, the production of polarised sunglasses has gradually evolved from the original sunglasses. This has made further changes in people’s lives and made further contributions to the protection of the eyes. People even in bright light can also carry out long-term activities, the eyes do not easily feel tired, to achieve the real protection of the function of glasses, but also to see things more clearly, three-dimensional, and more aesthetic nature.


     Scientists have proved that the ultraviolet rays in the sun will harm the skin, but there are many people also do not know that excessive exposure to ultraviolet rays in the sun will also be harmful to the human eye. Every part of the eye can be damaged in the process of exposure to the sun, and it can be cumulative. If this continues for a long time, the cornea of the eye, retina, crystal, etc., will have a destructive effect and will lead to cataracts, photo corneal eye, and other eye diseases.


     Although wearing sunglasses glasses can avoid such accidents, general sunglasses can only use the function of light reduction, because the general lens can not filter the sun’s rays, so it can only reduce the glare, ultraviolet light, etc. intensity, and can not completely block these harmful sun rays, so its function is only to reduce the damage to the eyes, can not completely prevent the people’s eyes from being harmed. But the biggest advantage of general sunglasses is the good popularity, so there are a lot of people who are wearing sunglasses.


     To reduce the damage to the eyes, polarised sunglasses have been introduced. Polarised sunglasses like the ones inside CheRing are equipped to filter the sun’s rays. Completely reducing the damage of glare, UV light, and other bright lights.

Because of:

  1. Polarised sunglasses have the function of polarising the light, which can prevent all the harmful light from reflecting outside the lens without affecting the passage of visible light, and play a good role in protecting the eyes.
  2. Not only does it have the function of an anti-ultraviolet ray, but also has the road surface reflecting light, water scale light, anti-glare, etc., which is very suitable for driving, fishing, traveling, and other daily life and work needs;
  3. Polarised sunglasses also have a good effect in the prevention and treatment of ophthalmic diseases, not only anti-glare, and play a role in dressing up.


     In a word, the special effect of polarised sunglasses is to effectively exclude and filter out the scattered light in the light beam. So that the light can be put into the eye’s visual image on the right track of the transmittance axis so that the field of vision is more clear and natural so that people can easily and naturally see the beautiful light under the strong sunlight.

     Polarised sunglasses have this characteristic, so they use this characteristic to block harmful light, so that no matter what object the sunlight touches, it will be naturally reflected or refracted to produce harmful glare. However, polarised sunglasses can completely absorb this glare, which can cause eye irritation and damage to the eyes, so that they can truly protect the eyes.
