Sunglasses Protect Your Eyes

People should wear sunglasses to protect their eyes against ultraviolet rays produced by sunlight in addition to fashion appeal. Exposure to radiation from sunlight has been associated with the development of cataracts, age-related macular degeneration and cancer among other diseases. Few people are aware that macular degeneration is an incurable eye disease and is the leading cause of blindness for those aged 55 and older in the United States.

Quality sunglasses protect your eyes from overexposure to sunlight by blocking 100 percent of the ultraviolet rays and screen out 75 to 90 percent of visible light.. In addition sunglasses will protect the delicate skin around your eyes from sun rays that cause wrinkles and premature aging.

Wearing sunglasses helps keep your eyes moist and comfortable by reducing the rate of tear evaporation. Your sunglasses act as an effective wind barrier and will help keep contact lenses from drying out. To prevent wind, dust and debris from getting into your eyes causing corneal abrasion choose a suitable pair of sunglasses.

Since your eyes require a certain range of ambient light for good vision, too much light is as bad as too little. This excessive brightness causes glare and squinting which can temporarily reduce your visual acuity. 

Sunglasses reduce glare for a safe and more comfortable vision. Surfaces like snow and water cause bright reflections that are distracting and interfere with your vision. On bright sunny days sunglasses will reduce the amount of light that reaches the retina of your eyes for an optimal level of comfortable vision. 

If you used to think that sunglasses were a fashion accessory designed to help you look attractive then remember that sunglasses protect your eyes. Wear protective eyewear any time your are exposed to ultra violet light even on cloudy days and during winter.
