We all know how handy a pair of polarized sunglasses can be on a hot and sunny day, but have you ever wondered where they get the superpower to protect your skin and eyes? Aside from offering a stylish spot of shade for your sensitive eyes, a pair of UV protected sunglasses will protect them from the harmful damage caused by the sun’s glare. To learn more about UV protection, polarization, and the benefits of sunglasses for your eyes, read this blog post.
Sun Damage: Risks
It may surprise you that your eyes are just as susceptible to damage from the sun’s harmful UV rays as your skin is. UVA rays in particular are capable of harming the retina in the back of the eyes, while UVB rays can ruin the outside of the cornea, which protects your eyes. Even in the shade, your sight can be worsened by strong glares. While a great pair of sunglasses is a fashion statement, it can also protect your sensitive eye lenses from getting cataracts, macular degeneration, and pterygium from the sun, which can all significantly impact your vision.
How it Happens
It isn’t the shade of lenses that determines the amount of sun resistance, but rather the percentage of UV protection they provide. When you are shopping around for a pair of your own, be sure to look for pairs that offer 100% protection from UV rays to be safe. A typical pair of sunglasses have lenses that are enrobed in a UV coating, which both absorbs and reflects the light that could negatively impact your vision.
A 100% effective UV protected pair of sunglasses will be able to block the invisible radiation the sun gives. In order to prevent eye damage caused by bright glare, a quality pair of sunglasses will also feature a polarizing film which gets rid of the glare that comes off of horizontal surfaces like roads and water.
When it comes down to sun protection, it is crucial your sunglasses are able to shield your eyes from the cancer-causing UV rays that put you at risk. Now that you know how effective they truly are, don’t forget to keep up with your routine eye exams to maintain your eye health.
