People of all ages need to take care of their eyes. This means that it is important to see an optometrist regularly. Another smart move is to wear sunglasses to protect your eyes from ultraviolet (UV) rays that are emitted by the sun. Not all sunglasses are created equal, and you may prefer one-of-a-kind custom frames to others. Our team at Eye Street Optical in Chantilly has gathered a few questions that we run into regarding sunglasses.
What are UV Rays?
UV rays are high-energy, invisible light rays that are produced by the sun. UV light rays are broken into three different categories: UVA, UVB, and UVC. The major differences between the three are UVA rays have longer wavelengths and pass through glass much easier than UVB and UVC. UVB rays are the most dangerous of the three, but they cannot go through glass. Thus, wearing sunglasses is a must to block these UV rays from your eyes. UVC rays never reach the earth's surface as the atmosphere blocks it from penetrating.
How Do Sunglasses Offer UV Protection?
The sun emits UV rays that can damage human eyes, even on a cloudy, overcast day. Sunglasses offer a form of UV protection. They block the rays with wavelengths up to 400 nanometers. This helps reduce glare and reflections, which are especially hazardous when playing a sport or driving. Also, it is wise to wear sunglasses when going to the beach, skiing, or boating. If your UV protective sunglasses become scratched or cracked from daily usage, then they should be repaired or replaced immediately. If the coating has become disrupted, then the UV rays will be let in and could damage your eyes.
What Color Lenses Work Best for UV Protection?
The color of your lenses is a personal choice as the options available will not affect how well they protect your eyes from UV rays. Gray and brown lenses are the more popular choices because neither color will distort the perception of moving objects. Professional athletes such as snowboarders, skiers, and baseball players prefer yellow lenses because they are adaptable in all sunlight conditions. Plus, yellow lenses reduce the appearance of hazy weather by increasing the contrast for a sharper image. Darker lenses decrease the amount of visible light available.
