The sun’s reflected light and glare can often be blinding and uncomfortable. Light scatters and bounces at different angles off an object’s irregular surface so that we can see it. But when the surface is smooth, the light has a tendency to reflect at one angle, and can reflect into our eyes directly. This concentration of light source reflected directly into our eyes is known as glare. Polarization is a technology that reduces light glare and improves vision. It improves the clarity of the lenses by creating more contrast while reducing eye strain by reducing the brightness on sunny days.
It is important to note that polarization does not prevent the sun’s harmful UV rays from harming the eyes, UV protected lenses do this function. Polarization is an added comfort for the eyes.
Polarized lenses have a chemical applied to them to filter light. The chemical’s molecules are placed linearly to block some light from passing through the lens like window blinds.
The chemical filter has vertical openings for light to pass through and will block all the horizontal light waves that bounce off smooth surfaces. This is why you see the view in front of you a bit darker than usual, but each element looks crisper and more defined, details are easier perceived.

- Increases visual comfort
- Reduces eye strain
- Allows for true perception of colors
- Enhances contrast and visual clarity
- Reduces reflections and eliminates glare
- Reduces tiredness from straining the eyes because of glare

Clearly (no pun intended), polarization is an impactful technology that lets you enjoy sunny days without the visual discomfort. It is especially appreciated while driving and fishing since it cuts the glare from the windshield and the surface of the water, allowing you to see the beauty of your surroundings.
With polarization, it is always a pleasure to be outdoors in the sun. Learn more about our Helios Eyewear lenses in lens technology
