COLORING YOUR PERCEPTION

While blue light plays an important role in helping regulate our bodies’ internal biological clocks, some research suggests that this portion of the visible light spectrum may also harm the retina and lead to age-related macular degeneration (AMD). The trouble is that the blue light not only comes from sunlight, but it is also emitted from artificial light sources such as LEDs, laptop computers, tablets, and smart phones. Because so many people regularly use one or more of these devices every day, protection against blue light may be deemed important for anyone using a digital device on a regular basis. With this in mind, older adults, in particular, may want to consider lenses that filter out blue light. There is no cure for age-related macular degeneration, but some treatments may delay its progression or even improve vision. It is especially important for adults who have had cataract surgery to wear protective lenses to provide maximal protection to the cells of the retina.
