We all know that light is fundamental for vision and allows you to make out shapes and detail. We also know that UV light is bad for the skin and eyes. A bit less well known is the effects of other colors of light. Take Blue-Turquoise light for instance. It aids in your overall well-being by helping with sleep/wake cycles, memory and basic mental functioning.

However, blue-violet light is harmful to retinal cells and is one of the risk factors for the onset of age-related macular degeneration (AMD). Since AMD is the number one cause of severe vision loss and legal blindness in adults over 60 it is important that we provide patients with the tools to help reduce their exposure to harmful light.
