How Do Polarized Lenses Work

Why We Need Polarized Lenses

When to Use Polarized Lens?

People who use Polarized Lens often say they are less tired than usual after hours of battling sun glare.  Polarized Lens can be a good choice for most everyday situations. These are some specific situations when polarized sunglasses may be especially helpful:

• Fishing. People who fish find that  Polarized Lens  drastically cut the glare and help them see into the water.
• Boating. A long day on the water can cause eyestrain. You may also see below the surface of the water better, which is important if you are driving a boat as well.
• Golfing. Some golfers feel that polarized lenses make it hard to read greens well when putting, but studies haven’t all agreed on this issue. Many golfers do find that polarized lenses reduce glare on fairways, and you can remove polarized sunglasses when putting if that’s your preference. Another benefit? Though this would never happen to you, golf balls that find their way into water hazards are easier to spot when wearing polarized lenses.
• Most snowy environments. Snow causes glare, so a pair of polarized sunglasses are usually a good choice. See below for when polarized sunglasses may not be the best choice in snow.
