It is long known that exposure to the sun\u2019s ultraviolet radiation can increase your risk for early-onset cataracts, macular degeneration and eyelid cancer. Did you know that your eyes are also sensitive to a portion of the blue light in the visible spectrum of light? Blue light (Blue-turquoise 465-495nm) benefits us by acting to regulate the circadian cycle and allows us to reset our biological clocks. While Blue-violet light (415-455 nm) can cause harmful oxidative changes to the retinal pigment epithelium cells promoting retinal damage.<\/p>\n
Blue light is not only found in the visible spectrum but is now used frequently in illuminating cell phones, computers and tablets. Energy-efficient fluorescent light and LED lights also emit blue light. How many hours a day do you spend on your cell phones and computers in a room illuminated by LED lighting or fluorescent lighting? Exposure to large quantities of blue light can cause an increase risk for macular degeneration. Therefore, people who have a family history or an increase risk of developing macular degeneration should consider protecting their eyes from harmful blue light exposure.<\/p>\n
Historically, blue blocking glasses were available but did not gain much popularity because the lenses were amber tinted and it changed the way people perceived color. Now, there are anti-reflective coatings available with blue-blocking filters that no longer impact color perception. Speak with your optometrist or ophthalmologist whether you can benefit from these protective features.<\/p>\n","protected":false},"excerpt":{"rendered":"
