The basic requirement of all qualified sunglasses is anti-UV, and the difference between ordinary sunglasses and polarizer is mainly in:
- principle
- Effect
- Usage scenarios
- Different principles
Ordinary sunglasses mainly rely on their own absorption of light to reduce the intensity of light, adding coloring compounds in the lens, blocking glare, no filtering effect on glare.
Polarizer is a lens made according to the polarization principle of light, filtering out many polarized light and glare in diffuse reflection, thereby weakening the intensity of light in the sky and making the field of vision clearer and more natural.
- Different effect
Ordinary sunglasses can weaken strong light, but they cannot filter glare. Diffuse reflection will still illuminate the human eye, causing indistinct front, serious color difference, eye fatigue and so on.
In addition to anti-ultraviolet and weakening strong light, polarizers can effectively filter glare and solve various “light pollution” in life. Play the role of anti-vertigo, the line of sight is more clear and natural deformation.
- Usage scenarios
Ordinary sunglasses can add a variety of coloring compounds to the lens, making different colors of the lens, a wide range of styles. If only as a fashion decoration, ordinary sunglasses can meet your needs.

Summary:
A good pair of sunglasses must be polarized!
A good polarizer needs to have: a clear field of vision to filter glare. Look, objects don’t deform. And the polarization rate can reach 99%!
