ExplainerHow do polarized lenses work?
Because the surface is horizontal, the light is reflected horizontally. When you are wearing polarized sunglasses, the surface blocks the glare by filtering out the horizontal light waves that don't fit through the chemical laminate pattern. Plus, polarized lenses also provide protection from harmful UV rays.

ExplainerAre Polarized lenses worth it?
Polarized lenses have become popular but are they really beneficial and worth the extra cost? Dark tinted glasses block more light than regular sunglasses but they still don't eliminate harsh glare as do polarized lenses. Also, if you do opt for dark lenses over polarized, make sure that they provide UV protection.

ExplainerWhat are polarized sunglasses made of?
The light coming through the filter is considered polarized. Polarized filters are most commonly made of a chemical film applied to a transparent plastic or glass surface. The chemical compound used will typically be composed of molecules that naturally align in parallel relation to one another.
Kiley Trimboli
ExplainerHow is polarized film made?
Polarizing film is made by dyeing film (mainly polyvinyl alcohol (PVA)) or by iodine being adsorbed onto its surface, then stretching and orientating it. This gives the film polarization characteristics that allow only light with a certain oscillation direction to pass through it.

ExplainerHow do you tell if a lens is polarized?
Look through the lens and check the level of glare.
If the sunglasses are polarized, you will notice the glare disappears. When you look through one of the lenses, it should be very dark and you should see little to no glare, but it will still look like the light is shining on the surface.

ExplainerWhat direction are sunglasses polarized?
Light that reflects off of a horizontal surface vibrates in the horizontal direction (polarized horizontally). So if the polarizer is oriented vertically, it will block that reflection. This is how polarized sunglasses block glare. Now take a look around and see if you can other sources of polarized light.

ExplainerWhat color lens is best for driving?
Although gray and green lenses have their own benefits, and colorful lenses are fun, copper and amber tints increase contrast, making them the best options for driving. If you're looking for a crisp, clear view, we suggest finding a pair of shades with amber or copper lenses – and extra points if they're polarized.

ExplainerIs polarized better than non polarized?
A high quality pair of sunglasses may include polarized lenses. A polarized lens offers the following advantages over non-polarized lenses: Increases visual comfort. Since your eyes aren't constantly challenged by glare, it is easier to view objects in bright conditions.
Xiaopeng Echarren-Sanz
ExplainerWhy do polarized sunglasses hurt my eyes?
The defected lens of the sunglasses could also be a possible reason for the resultant headaches of wearing polarized lenses. The coating of the polarized lenses makes it difficult, and induces a strain on the nerves of the eyes, which cause severe headaches.
Atsuko Bachert
ExplainerAre Polarised sunglasses better for driving?

ExplainerWhat is light polarization?
A light wave that is vibrating in more than one plane is referred to as unpolarized light. Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization.
Hipolit Veigt
ExplainerIs anti glare the same as polarized?
The AR coating basically reduces glare and “ghost” images due to reflections at the lens surfaces. It works indoors and outdoors. Polarized lenses are primarily for outdoor use and are used to glare from smooth surfaces. Get anti-glare coatings on your glasses to reduce glare off of the glass on your lenses.
Imanol Munguira
ExplainerWhat is non polarized?
Polarized lenses have a filter laminated on them that only allows vertically oriented light to pass through, while non-polarized lenses are usually just tinted to block light. Non-polarized lenses do not contain a filter to remove glare.
Malak Pinna
ExplainerDo they make clear polarized glasses?
Unfortunately No, polarized lenses don't come in clear. The polarizing filter will always lend some tint to the lenses. It is available in lighter tints though.

ExplainerWhy reflected light is polarized?
If light strikes an interface so that there is a 90o angle between the reflected and refracted rays, the reflected light will be linearly polarized. The electric field vectors in the light match the direction the electrons were oscillating, and they must be perpendicular to the direction of propagation of the wave.
