Why sunglasses are necessary

  1. 1. Why Sunglasses are Necessary http://www.matrixeyewear.com
  2. 2. Introduction <ul><li>Sunglasses play a large part in our modern fashion culture; many a movie star has graced the red carpet looking suave in a pair of shades. </li></ul><ul><li>But beyond being the ultimate fashion accessory, sunglasses also play a critical role in our health and safety. </li></ul><ul><li>Sunglasses are just as vital as sunscreen when spending prolonged periods of time outside. </li></ul>
  3. 3. Ultraviolet Protection <ul><li>Most people are aware of the impact that ultraviolet rays have on the skin, but few are aware of the damage they can have on the eyes. </li></ul><ul><li>Radiation from ultraviolet rays can speed up the development of cataracts and age-related macular degeneration (AMD). AMD is a disease that destroys the sharpness of vision. </li></ul><ul><li>It is a painless disease, so most people are unaware of the damage they are doing. AMD is the leading cause of loss of vision in people 60 years of age or older. </li></ul><ul><li>Wearing sunglasses protects you from these harmful ultraviolet rays. </li></ul><ul><li>Be sure to check that the sunglasses you are buying offer satisfactory UV protection. </li></ul><ul><li>A quality pair will give you 100% protection from UV radiation. </li></ul><ul><li>Many people are using polycarbonate lenses because they are a natural filter to UV and need no additional coating. </li></ul>
  4. 4. Glare Reduction <ul><li>The reflection of light puts great strain on our eyesight. </li></ul><ul><li>Surfaces like snow and water can be extremely bright and as a result, extremely dangerous. </li></ul><ul><li>Bright sunlight has been the cause of countless accidents when driving or when playing sports. </li></ul><ul><li>These accidents could have been averted if the individual had been wearing sunglasses. </li></ul><ul><li>Polarized lenses are particularly effective at blocking out the harsh glare of the sun. </li></ul><ul><li>These sunglasses have been popular for a longtime with the boating and fishing communities, reducing the reflective glare from the water. </li></ul><ul><li>In fact all outdoor enthusiasts can benefit from wearing them. </li></ul><ul><li>Post-cataract patients and light-sensitive people wear polarized sunglasses as well, to soften the bright light indoors. </li></ul>
  5. 5. Headaches and Eyestrain <ul><li>The pupil of the eye controls how much light reaches the retina. </li></ul><ul><li>In dark conditions, the pupil will increase in size to let more light in, and in bright conditions it will constrict to block out the excess light. </li></ul><ul><li>Continual exposure to bright light causes squinting because the pupil cannot constrict far enough to reduce the amount of light. </li></ul><ul><li>This causes muscle fatigue and as a result headaches and eyestrain. </li></ul><ul><li>By simply wearing sunglasses, the pupils can relax and squinting will be reduced, avoiding discomfort. </li></ul>
  6. 6. Eye Safety <ul><li>Dust and debris caught in the eye can lead to corneal abrasion. </li></ul><ul><li>Wind can cause contact lenses to dry out and tears to evaporate, making the eyes dry and uncomfortable. All of these problems can be avoided by wearing sunglasses. </li></ul><ul><li>Polycarbonate lenses are seen as the most durable and safest lenses to wear. </li></ul><ul><li>They are less likely to break or fracture and are much safer than weak plastic lenses. </li></ul><ul><li>If you are in a situation where you are exposed to windblown particles, wraparound polycarbonate sunglasses are recommended. </li></ul>
  7. 7. Bottom Line <ul><li>As you can see, sunglasses are both fashionable and practical. </li></ul><ul><li>Wearing a pair can increase your comfort, your style and most of all, your safety. </li></ul>
