Sunlight scatters in all directions, bouncing off uneven surfaces like rocks and other similar objects. However, if it hits a flat surface like a piece of metal or a body of water, it travels in a uniform, more horizontal direction. This creates a dangerous and intense burst of light that causes glare and reduced visibility.
If you have been dealing with the issue of glare every time you spend time outdoors this summer, it might be time to visit an eye doctor who can recommend polarized sunglasses. Here’s what you need to know about this special kind of eyewear.
How Do Polarized Eyeglasses Work?
Polarized sunglasses work by preventing glare from hitting you directly in the eye. They have special lenses coated with chemicals that block light rays moving on a horizontal plane and allow only those moving vertically to pass through. When the sun’s up and you wear polarized sunglasses, you’ll notice that the objects you see become darker than usual but with clarity and more detail. With the lenses doing their job, your eyes feel less tired and are less likely to squint.
Who Can Wear Them?
Polarized eyeglasses are commonly worn by people who perform outdoor activities. Fishermen and boaters, for instance, wear them to protect their eyes from the intense sunlight bouncing off the sea, lake, river, or any body of water. Outdoor enthusiasts like cyclists, skiers, golfers and runners also benefit from this advanced eyewear. So are people whose jobs require them to be outdoors like on-duty police officers and military and security personnel. After an eye exam, the eye doctor may also prescribe polarized sunglasses for individuals with light sensitivity, including those who have had cataract surgery.
What to Look for in Polarized Sunglasses
Polarized sunglasses can have extra features depending on your needs. You can ask your eye care professional about having an anti-reflective coating applied to the backside of the lenses. When the sun is behind you, these coatings help reduce distracting reflections from the back surface of your eyewear. Also, keep in mind that not all polarized sunglasses protect you from the sun’s harmful UV rays. When shopping for a pair, ask if they come with a UV protection coating.
