How to Tell if Sunglasses are Polarized
Posted by Shark Eyes on 30th Oct 2020
Are your eyes sensitive to the light? Wearing polarized sunglasses offers an awesome and effective way to block-out the sun's glare. Sunglasses that are polarized also protect your eyes from the sun's harmful UV rays and untinted polarized lenses can even give you relief from blue light.
How Polarized Sunglasses Work
Polarized sunglasses block the glare of a reflective surface, like the sun, by filtering out the horizontal light waves. Glare is caused when a bundle of light bounces off an object, resulting in horizontal light waves that our eyes have trouble adjusting to. When sunglasses are polarized, only the verticle light waves are allowed into your eye. Vertical blinds use a similar concept to screen out horizontal lights but on a lesser level than polarized glasses do.
You may notice things are darker when wearing polarized sunglasses, but you'll still be able to see. You'll find when wearing your protective glasses, your vision is no longer as sensitive as they were without shades.
Wearing a pair of polarized sunglasses not only shades your eyes from the reflective glare of the sun but also gives you UV protection too. UV protection for your visual area is just as vital as sunscreen is for your skin.
Polarized lenses are also helpful in keeping out blue light that comes from computers, tablets, and televisions that can damage your vision and give you headaches too.
Who Needs Polarized Lenses?
Lenses that are polarized are beneficial for everyone. While regular sunshades shield some glare, polarized ones are by far the best at keeping the sun's glare in check. Also, when the lenses block horizontal lights, you know for sure they are keeping out harmful rays too.
Are Polarized Lenses Right For Me?
If you are wearing regular sunshades and are thinking of getting a new pair, going with a polarized version, you'd be making a wise decision. Shop around for a pair that fits well and offers the best shielding. They come in varying grades so it is to your advantage to shop for the best fit for you.
Putting Your Sunglasses to the Test
Maybe you just ran into a pair of sunglasses from last year or purchased a pair that didn't specify if what type they were. If so, you may be wondering how to tell if your sunglasses are polarized. Some sunglasses are tinted but that doesn't mean they're polarized. Knowing the difference can make a huge difference. Here are a few ways to check:
- While wearing the pair of sunglasses in question. pick one reflective object, like a shiny metal object. While tilting your head to the side so that it's at a 60 degree angle, look closely at the one object. Look to the left or right. Is there any change in the quality of the surface you see? If there is, your lenses are polarized.
- If you are wearing contact lenses, there's another step to take in determining if the sunglasses have polarized lenses or not. Take off your contacts and follow through with the step above if you feel that the sunglasses may be prescription lenses. Choose one reflective object and tilt your head 60 degrees. If there is no change, try a 90 degree angle. If the surface source you are observing changes, the sunglasses are treated with polarization. Please note that you will want only one of your lens, contacts or sunglasses, to be prescription polarized. Not both. Having the lens of both polarized in a prescription lens will make things look blurry at best. It may even be impossible to see out of them.
Tips on Polarized Sunglasses
Now that you have put the sunglasses to the test to see if they are polarized, here are some suggestions:
- Polarized lenses are so beneficial to the health of your vision, it's a good idea to have two pairs of polarized sunshades. You can rotate one pair or even keep one of the shades in the car for backup and the best pair on you at all times.
- If you only have one pair of polarized sunglasses, it would be your best bet to get a new pair so you have two. Having two pairs helps ensure you are never without protection because we all know how difficult it can be to keep up with sunglasses. When you need them the most, you can't find them.
- If you wear corrective lenses, you can get sunglasses polarized and in a prescription that is the same as your glasses or contacts. You can get one eye in a different prescription than the other if need be, unlike if you get a set that is already in a prescription. Get a vision check first. That way you can make sure the new polarized sunshades are the right formulation for you.
