In honor of Stress Awareness Month, we would like to cover a topic that is causing stress to your patients’ eyes – Blue Light. For those who haven’t heard, blue light – or more specifically, artificial blue light, can be harmful for your eyes and is found in things like LED lights, cell phones, e-readers, and computers.
Found within the visible light spectrum, blue light has a shorter wavelength and higher energy, which makes it harder on our eyes. This distress is the result of a flickering caused by the shorter wavelength which, in turn, causes eye fatigue without you even noticing.
So why should your patients care?
Blue light has been identified as the most dangerous light for our retinas and, after chronic exposure, people can expect to see increased incidences macular degeneration, glaucoma and retinal degenerative diseases. While our eyes may have natural filters, they are not enough to protect us from overexposure to blue light.
How to protect your patients?
When discussing blue light with your patients, you can suggest that they avoid using their digital devices an hour before going to bed, keeping balanced lighting around their devices, employing the 20-20-20 rule (looking 20 feet away from your devices for 20 seconds, every 20 minutes) and investing in special lenses. Whether your patients need a prescription or not, wearing lenses that have a coating to filter out blue light can help prevent some of the symptoms of digital eyestrain. Plus, it’s a great excuse to wear fashionable frames!
