🕶 SUNGLASSES 🕶
Have you ever heard the terms “polarized sunglasses” or “UV protection” but have no idea what they mean or why they’re important? If so, this post is for you.
When choosing a pair of sunglasses, it’s important to consider the kind of protection your sunglasses offer. Most sunglasses offer UV protection and this is why:
UV rays are invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation that reaches the Earth's surface is made up of two types of rays, called UVA and UVB. Why are UV rays bad? UV rays can have a serious negative affect on your vision. Both short-term and long-term exposure to UV radiation can compromise your eye health and lead to several eye diseases and conditions such as Macular Degeneration, Cataracts, Photokeratitis and Cancer.
Next we have Polarization:
All light travels in waves, which means that it vibrates. Normally light vibrates in multiple directions but when it bounces off a horizontal surface such as water, snow or the roof of a car, it only vibrates in one direction – horizontally. When this happens, the process is called “polarization”. Why is this bad? Because the light is only bouncing in one direction, it becomes concentrated and hits the eye directly. This concentrated light is called “glare” and causes the eye discomfort and strain. Eye strain can lead to blurred vision, headaches and fatigued – but it will NOT damage your eye.
So, do you really need Polarized sunglasses? While polarized lenses will not protect your eyes from UV damage more than standard 100% UV, they can give you clearer, more accurate vision and alleviate some eye strain. Athletes and outdoor hobbyists often use polarized sunglasses so they can see with a higher degree of precision. Polarized lenses are an excellent choice for:
· Golfers
· Skiers
· Fishermen
· Motorcyclists
· Beachgoers
If you find yourself squinting a lot, even when you’re wearing sunglasses, consider investing in polarized sunglasses. And whatever you do, remember to protect your eyes from ultraviolet rays. Ensure your sunglasses offer 100% UV protection and wear them anytime you head out into the sun.
