For a fashionista, a pair of sunglasses is seen as a fashion accessory, something that can amp your style and outfit for the day. But for a health buff, this eyewear is an important device for blocking harmful UV rays from the sun.
Harmful Effects of UV
The ultraviolet rays of the sun don't only damage the skin but also harm the lens and cornea of the eyes. They also increase the risk of cataract, a condition characterized by clouding of the eye's lens resulting to diminished vision.
UV rays also shoot up the likelihood of developing macular degeneration, a disease of the macula that contributes to less sharp vision.
Other UV-related vision problems include pterygium, pingueculum, and photokeratitis or snow blindness.
Wearing the right pair of shades can help save from these ailments. Here's how to choose the right product in the market.
Buy Sunglasses with UVA and UVB Protection
Some sunglasses only protect against UVA rays. In order to get full protection against UV rays, get a pair that shields against both UVA and UVB rays. Check out the label of the sunglasses.
Any of these indicate full protection:
- lenses that block 99 to 100 percent of UVA and UVB rays
- ANSI Z80.3 blocking requirements
- UV 400 protection
UV 400 protection means that the sunglasses can block light rays with wavelengths that go up to 400 nanometers. In other words, even the tiniest UV rays are shielded.
Pick the Right Color for Your Eyewear
It's not necessary to choose darker lenses since the coating that blocks UV rays is clear. However, you still need to choose the right hue for the purpose of ease in color perception. For example, yellow or rose tinted lenses make it a challenge to distinguish traffic lights. These colors should be off-limits to those who drive. It's better to choose gray, green or brown lenses, which are less prone to color distortion. Especially if you drive a car, these colors are the better choices.
Choose Polarized Lenses
Polarized lenses are the suitable choice if you're going to spend a lot of time near water. These sunglasses filter the reflected sunlight from water or even pavement. It's a wonderful choice for boaters, water skiers, anglers and beach enthusiasts. Take note that it can be difficult to read cell phones, GPS devices, and ATM when you wear these sunglasses. Make sure that you read the label first for full UV protection before purchasing.
Check the Quality of the Lens
The price isn't the sole factor for determining extensiveness of UV protection. But it's usually better not to rely on overly cheap sunglasses that are also cheap in quality. You don't want to spend a fortune on your pair of shades but at least set aside some budget so you can invest on a worthy buy.
Remember that Bigger IS Better
The more coverage the sunglasses have on your eyes and face, the better. In fact, the best option would be the wraparound sunglasses because they can also shield your eyes against light coming from the sides.
