In its simplest form, blue light is short wavelength and high energy light. In general, this high energy light bad for our eyes. The eye by itself is not great at blocking blue light, especially if you have had cataract surgery. 

Man-made blue light specifically from fluorescent lighting, LED lighting, and light from screens and handheld devices has negative consequences. The most prevalent are digital eyestrain, macular degeneration, and it can disrupt sleep patterns by altering our circadian rhythms. 

As a result, we recommend blue light filtering lenses. We use the Eyezen+ brand of lenses to minimize digital eyestrain and protect your eye health. These lenses are available with and without prescriptions, so EVERYONE benefits. If you have any questions or comments, please send an email to drlillie@allendalefamilyvision.com
