How do polarized lenses work?
Polarizing lenses block harmful glare
Simply put, good quality polarized lenses make life easier on the eye by reducing glare.
- No need to squint in bright sunlight or in sky's white light when it's hazy
- More comfortable to see while driving, cycling, skiing, sunbathing or for everyday use
- Reduced risk of eye strain and headaches by protecting the eye from overwork
- See true colours and contrasts, important for driving safety and water sports
- See objects or road markings otherwise obscured by intense reflected glare
- Ability to wear sunglasses for prolonged periods without eyestrain

What is glare and how do we block it?Visible light waves from the sun travel in all directions. When sunlight reflects off a horizontal surface, like a road or water, it often becomes concentrated horizontally. This is known as glare. Vertical light is useful to the human eye. But glare masks useful light, making it difficult and uncomfortable to see. |
