Everything You Need to Know about Polarized Sunglasses
Polarized sunglasses are modern eyewear specially designed to reduce glare from water, glass, and snow. As you may have experienced, glass distorts the real color of objects, making it harder for you to distinguish between them. Sportsmen and people who drive on a daily basis may see more clearly with these glasses. Hence, the risk of potential accidents and hazards are reduced.
Polarized sunglasses come in a variety of colors based on the material of the lenses. Generally, polarized lenses come in grey and brown colors. However, you may find other colors, including yellow, green, and melanin depending on the manufacturer. Typically, the darker the shade, the higher the level of polarization it’ll provide.
The core principle behind these sunglasses is a natural phenomenon. Sunlight can be absorbed or reflected in different directions. When the rays of the sun bounce off horizontal surfaces, such as land, water, or a car’s hood, they tend to reflect in a similar horizontal direction. Frequently, this reflection results in a glare that can cause visual difficulties but can also become potentially blinding. This may particularly pose a severe risk to drivers. Polarized lenses feature a laminated filter that only allows the passing of vertically reflected light. Blocking the horizontally-oriented light, it eliminates glare to a significant extent. The advantages of polarized lenses are:
- Reduces visual discomfort
- Relieves eye strain
- Improves contrast
- Offers clear vision
- Allows true perception of colors
- Reduces reflections and eliminates glare
