Ultraviolet (UV) radiation from the sun is a concern for everyone. Most people are aware of the importance of protecting their skin, but not their eyes. Eye diseases like cataracts and macular degeneration are related to UV exposure throughout your life. Protecting your eyes from UV exposure may preserve your vision later in life.
- UV exposure to the eyes causes cataracts, macular degeneration, photokeratitis, pinguecula and pterygium.
- UV intensity is usually greater during mid-day.
- UV radiation can pass through dense clouds, so it is important to have sun protection even on cloudy days and during winter.
- UV can reflect off water and snow, so sun protection when doing water and winter sports.
- Children are more susceptible to UV radiation since they spend more time outdoor.
- Certain medications such as oral contraceptives and certain types of antibiotics, make you more susceptible to UV damage.
- Tinted lenses do NOT necessarily block off harmful radiation. In fact, tinted lenses without UV block make your pupils larger letting more harmful radiation reaching your eyes.
UV Protection Options:
- Permanent tinted lenses (prescription or non-prescription) that block out 99-100% of UVA and UVB radiation
- Grey-coloured tinted lenses offer the most natural color vision, although some people prefer the warm colour from brown-coloured tinted lenses.
- Photochromic or Transitions lenses turn dark when the lenses is exposed to UV radiation. However photochromic lenses may NOT turn dark enough when you are driving, as the windshield blocks off some of the UV radiation that enables the lenses to turn dark.
- Polarized lenses effectively blocks off reflected glare (reflection off the ground and water) and UV radiation. These lenses have the best optics and are useful for people who drive and play water sports.
- Clear lens with UV-tint may be a good choice for those who want UV protection without the darkening effect.Talk to us about your lifestyle and hobbies so we can personalize your UV protection option.
