Just What the Doctor Ordered

Ophthalmologists are proponents of the benefits of sunglasses protection. Not only are wholesale sunglasses fashionable, but they also provide long-term health benefits.

Sunglasses help improve visual clarity by reducing eyestrain and glare. Often time’s sunglasses can help people with their night driving. Increasing vision in bright light saturating environments is also necessary for outdoor adventure enthusiasts.  For example, people who engage in snow sports activities find that the proper tinted goggles actually increase their depth perception. Avid anglers wear sunglasses to help reduce water surface glare, allowing them to have better visual perception of their surroundings. X-Loop sunglasses and Chopper sunglasses offer 100% UV protection.

While sunglasses offer obvious protection from glare and dramatically increase visibility, they also offer some imperceptible benefits. Sunglasses with UV protection shield damaging ultraviolet radiation rays. UV rays can cause both short- and long-term ocular issues and damage. Photokeratitis is a condition where the cornea and conjuctiva become sensitive due to a type of sunburn. Do you remember how parents always forbade children to stare at the sun saying if they did, it would hurt their eyes? There actually is truth to that childhood saying! Symptoms of this condition include pain, discomfort, excessive tear production and twitching. Other types of disease and illness associated with excessive ocular UV rays include cataracts, which is a light obstructing cloud that develops on the eye’s lens. Pterygium is a deterioration of the eye’s collagen tissues and can require surgery. In severe cases, eye cancer is also associated with excessive UV exposure.

Recently, scientists have discovered that HEV – high-energy visible light – is linked to macular degeneration. As children’s eyes are thought to transmit and absorb more HEV light, it is especially important for them to wear sunglasses that filter this damaging light.

In order to protect the eyes, sunglasses must fit properly. Sunglasses should be somewhat form fitting, allowing as little light to reach the eyes as possible. In order to determine if sunglasses are a proper fit, consumers should move their head from side to side to see how much light is accessible.

Lens color is not a sign indicative of UV protection. UV protection has nothing to do with dark lenses, as different colors provide different additional benefits. For example, gray and green lenses allow colors to remain neutral. Brown lenses dramatically increase contrast. Turquoise-colored lenses are excellent for medium- to high-light conditions, enhancing contrasting images. Orange and yellow lenses help increase depth perception as well as increase contrast. Blue or purple lenses are typically fashionable and purely cosmetic. However, in order to determine UV protection, it is important to read the types of coatings, not related to color, that the manufactured used on the lenses.

Protecting your eyes today can lead to a longer, healthy life in the future.
