Replica dior sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun's ultraviolet (UV) rays. Some of the sun's effects on the eyes include: Cataracts, a clouding of the eye's lens that can blur vision. An estimated 20% of cases are caused by extended UV exposure.

1. PREVENT SUN-RELATED HEALTH PROBLEMS

Our eyes are sensitive. Prolonged exposure to sun can lead to a variety of ailments. Some are simply painful or irritating, others can be deadly serious. But remembering to wear a pair of high quality sunglasses can help to keep you safe from the sun’s damaging rays.

Let me start by defining what I mean by “high-quality” replica dior composit sunglasses. When choosing sunglasses, start by looking for cheap sunglasses with 100% UVA and UVB protection. This provides full protection against the sun’s ultraviolet rays. Polarized sunglasses can reduce glare, which is nice if you’re spending a lot of time on the water. Also look for eyewear that fully cover your eyes. Wrap-around lenses are even better because they block out light and glare from the side, as well as the front.

2. UV Protection

The sun's UV radiation can cause cataracts; benign growths on the eye's surface; and photokeratitis, sometimes called snow blindness, which is a temporary but painful sunburn of the eye's surface. Wide-brimmed hats and caps can block about 50 percent of UV radiation from the eyes but optometrists say that is not enough protection.

3. Prevention Macular Degeneration

Over time UV light may play a role in damaging the macula lutea (an area of the eye with millions of light-sensing cells, which allow us to see fine details clearly), potentially leading to blurriness and vision loss.

When purchasing sunglasses, look for ones that block out 99 to 100% of both UVA and UVB radiation, so you can keep your vision sharp and eyes healthy. A wide-brimmed hat offers great protection, too!
