We all hear about wearing protection...from UV rays. But what do you really know about UV rays?


What Are UV Rays?


UV (ultraviolet) rays are a type of electromagnetic radiation that come from the sun and are invisible to the naked eye. UV rays can be divided into three types: UVA, UVB, and UVC.


Two of those, UVA and UVB, can cause harm to our eyes. UVA rays can go deep inside the eye and cause damage to the retina, while UVB rays can damage the front part of the eye, including the cornea and lens. If we are exposed to UV rays for a long time, it can cause eye problems such as cataracts, macular degeneration, and photokeratitis (an eye condition similar to sunburn). Wearing sunglasses that block 100% of UVA and UVB rays, and a hat to block some of the sun's rays, can protect our eyes. Even on cloudy days, it's a great idea to wear protective eyewear, and even a hat, as UV rays can still penetrate through.


Sunglasses Are a Must-Have Accessory When It Comes to Eye Protection


They not only enhance your style but also shield your eyes from harmful UV rays. However, not all sunglasses are created equal, and it is essential to choose the right pair for maximum eye protection. In this blog post, we will provide you with tips on how to choose the right sunglasses to protect your eyes from UV radiation.


  • Look for UV Protection: UV radiation can cause significant damage to your eyes, including cataracts and macular degeneration. Therefore, it is essential to look for sunglasses that offer 100% UV protection. This means that the sunglasses should block both UVA and UVB rays. Check with your eyecare professional or read the label to ensure that the sunglasses you choose provide this level of protection.
  • Consider the Color and Tint: The color and tint of sunglasses don't affect the level of UV protection, but they can influence how comfortable they are to wear. Some people prefer darker lenses, while others prefer lighter lenses. It's a personal preference, but make sure to choose a tint that doesn't affect your ability to see clearly.
  • Choose the Right Frame: Size matters. The frame of your sunglasses can also impact the level of protection they provide. Look for frames that cover your eyes and the skin around them. Wraparound frames are an excellent option as they provide extra coverage. Make sure the frames fit well and don't slip or move around.
  • Polarized Lenses: Polarized lenses can reduce glare and improve visibility, especially in bright sunlight or near water. However, they don't offer additional UV protection. If you spend a lot of time near water or in bright sunlight, consider investing in polarized lenses for added comfort and clarity.
  • Prescription Sunglasses: If you wear prescription glasses, consider investing in prescription sunglasses. This way, you can protect your eyes from UV radiation and have clear vision at the same time. Talk to our professional eyecare staff at Urban Optiks about getting prescription sunglasses.


Your Sunnies Are Your Friend


In addition to looking fabulous, sunnies are a necessary tool for protecting your eyes from harmful UV radiation. When choosing the right pair, consider UV protection, color and tint, the frame, polarized lenses, and prescription sunglasses. Keep these tips in mind the next time you need a new pair of sunglasses to ensure you are getting the best protection for your eyes.
