How Polarized Lenses can Protect Your Vision
Even if you’re putting on sunscreen every time you go outside, you may not be doing everything you can to protect yourself from the sun’s harmful rays. Sunglasses may seem like an optional accessory, but they’re actually crucial to protecting your eyes from UV rays, especially if they’re polarized.
How do polarized sunglass lenses work?
Polarized sunglasses reduce allow for clearer vision on sunny days, and many come with anti-reflective coating to increase clarity. Essentially, they act like venetian blinds as the sun bombards the eye in all directions, controlling the flow of light to minimize glare.
How Polarized Lenses filter UV rays
Polarized lenses control incoming light to protect your eyes from harmful UVB and UVA rays, while non-polarized lenses only protect from UVB. UVB rays endanger the tissue in the cornea and lens, while lower energy UVA radiation penetrates deep into the eyes to damage the macula, which controls your center field of vision.
Radiation like this can result in cataracts, corneal sunburn, macular degeneration and skin cancer among other things. Many of the conditions that come from poor eye care result in vision loss. While polarized lenses cost a little extra, they also prevent eye diseases and protect your vision and the skin of your eyelids.
It’s also a crucial but commonly overlooked fact that parents must make sure their children have proper eye protection. Many kids find sunglasses uncomfortable or forget to wear them, and only 58% of adults make sure their children wear sunglasses.
Children and teens are at a stage where their eyes are changing, and protecting their eyes now reduces their risk of developing eye problems later in life. Putting sunglasses on them is as important as making sure they’re covered in sunscreen.
