One of the marketing claims I believed was polarised sunglasses offers more sun protection than the generic UV-protective sunglasses. This claim was more than enough to justify the extra expense that I pay for my Polarized Ray Bans.
Your eyes can be harmed by UV rays both immediately and over time. Opthalmologists say that it is possible to get keratitis, akin to sunburn on the eye. Long-term UV exposure can raise the chance of other conditions such as cataracts, macular degeneration, or eye malignancies
For anyone who spends a lot of time outside, polarised lenses are a fantastic alternative. Polarized lenses can reduce glare from horizontal surfaces and provide more clarity when working outside such as when you’re driving a lot or spending lots of time working by the beach, water or snow. Though it’s a bit expensive, it’s a perfect accessory for those that spend a ton of time outdoors.
However, science doesn’t back up the claims that polarised glasses offer more sun protection more than the unpolarised sunglasses. As long as you are wearing UV protective lens, then you should be fine. Generally, larger frames offer more protection from all angles and sides. Sunglasses are one of the accessories you can use even on winter.
Benefits and Disadvantages of Polarised Glasses
The other benefits of wearing polarised lenses include: having clearer vision especially when working in very bright light conditions, increased contrast and seeing the environment vividly, reduced glare and eye strain.
Some disadvantages of wearing polarised glasses includes difficulty when looking at LCD lenses such as car monitors, cellular phones and TV, and difficulty seeing in low light conditions such as when driving at night.
To sum things up, polarised glasses offer a ton of benefits for others and not for some. Just like with the other factors we consider when choosing sunglasses such as style and comfort, the type of lens is just another factor we have to consider. It’s a good upgrade but not entirely an essential one.
