Polarized Safety Glasses work by shielding your eyes from the direct attack of reflected light, which is how they get their name. You have proper vision when the eye picks up on light rays that have been reflected off of an object. In a normal circumstance, that light will be dispersed in some manner before it reaches your eye. In most cases, it is doing so because of the uneven surface of an object, such as skin or a rock, which causes it to bounce off multiple angles.
The light is transmitted more efficiently across surfaces that are highly reflective, smooth, and flat. Some examples of such surfaces include water, metal, and snow. This is because its reflection does not become scattered before reaching the eye.
They do this by applying a specific chemical coating to the polarised lenses, which prevents some of the light from penetrating the lenses. It functions as a filter for whatever is reflected directly into your eyes, keeping undesired components out.
When it comes to polarised lenses, the filter is in the vertical position, which means that only a portion of the light can get through the gaps. Polarized lenses are designed to eliminate glare, which is caused by the horizontal light, by filtering out all but the vertical component of the light spectrum. Polarized lenses help to eliminate glare by blocking horizontal light, which reduces the amount of light that is shining directly into your eyes.
