What's the point of sunglasses? Why protect your eyes? Time to learn how to take care of your eyes with a pair of sunglasses!
What are the different types of sunglasses lenses?
Different types of lenses are suitable for different purposes, be it driving, convenience, or super bright conditions. Learn how the different types of sunglass lenses work and which one is right for you.
Gradient
Top-down tinted to protect eyes from overhead sunlight, gradient lenses also allow more light to pass through the lower half.
Mirror coating
In addition to making you look like a secret agent, mirror-coated lenses are ideal for ultra-bright conditions.
Photochromic
Also known as "transition lenses," the tint of photochromic lenses automatically adjusts when exposed to sunlight.
Prescription
The days of clip-on or magnetic sunglasses are over when you choose prescription sunglasses lenses. You can buy lenses that have your prescription tinted to whatever darkness you want.
How are sunglasses polarized?
Sunglasses are polarized by laminating special chemicals on the lenses in a vertical pattern. Polarized sunglasses are great for protecting your eyes from sun damage because they block horizontal light and glare.
Think of the blinding glare on the hood of an oncoming car or the discomfort caused by wildly heavy snow on a sunny day. With a pair of polarized sunglasses, you don't have to worry about discomfort or distorted vision due to glare.
As you can see, polarized sunglasses are especially useful when fishing, skiing, or driving because they block horizontal light. On particularly sunny days, these shades will make these activities safer and more fun!
Why are the sunglasses black?
Sunglasses are dark because it blocks some of the visible light, but you don't necessarily need the deepest lenses to protect your eyes. More than 40% of Americans believe dark sunglasses provide more UV protection, which is inaccurate. Light-tinted and clear lenses can also provide UV protection.
The most popular shade for sunglasses is gray. Gray is a neutral color that doesn't distort colors and also reduces brightness and glare. On cloudy days, amber or brown sunglasses will add contrast and brighten your vision. Consider using yellow or orange lenses in foggy or low-light situations.
Different shades offer different benefits and are best for a variety of activities, but no matter which shade is your favorite, you should always wear lenses with UV protection.
How do sunglasses protect the eyes?
Sunglasses protect your eyes by acting as a barrier to reflecting UV rays. Sunglasses are the equivalent of sunscreen for the eyes. In addition to being a beach accessory, they also protect your eyes from the sun's harmful rays. Experts recommend that your sunglasses protect your eyes from at least 99% of UV rays.
As you can see, the sun's rays can penetrate different areas of the eye. UVA rays can reach the retina at the back of the eye, while UVB rays can reach the cornea at the front of the eye. Sunglasses prevent these rays from penetrating your eyes, preventing potential injury or vision loss.
How often should you change your sunglasses?
You shouldn't just replace your sunglasses after they've been scratched or lost. In fact, the UV protection on sunglasses lenses wears off over time, which means you should replace your sunglasses every two years or so.
To properly protect your eyes, it is important to change your sunglasses to reduce the risk of UV radiation. If you're wondering if it's safe to wear your old favorites, you can take them to your local eyewear retailer, who can test for UV protection levels.
