Polarized Sunglasses vs Standard Tinting


Ultraviolet rays from the sun are incredibly damaging to our eyes, so proper eye protection is important at any time of year. However, choosing the right sunglasses is no easy task with so many choices available.

Polarized sunglasses are specialized eyewear designed to reduce GLARE from surfaces such as water, snow and glass.

First, we need to know what GLARE is. Glare is difficulty seeing in the presence of bright light such as direct or reflected sunlight. It can generally be divided into two types, discomfort and disability glare. Discomfort glare is an instinctive desire to look away from a bright light source.

Disability glare impairs the vision of objects without necessarily causing discomfort. This could arise for instance when driving westward at sunset.

How do Polarized Lenses Work?

Sunlight can be absorbed or reflected in several different directions. Sunlight that bounces off horizontal surfaces, such as water and land, is usually reflected back in a similar horizontal direction. This causes not only visual discomfort but can also cause a potentially blinding glare.

Polarized lenses contain a laminated filter that allows only vertically oriented light to pass through.
