The Digital Age of Eye Care
Staring at your phone. Staring at your computer. Staring at Netflix. There’s no shame in it – we all do it, and in the last year our screentime has collectively increased as FaceTime and Zoom have taken the place of in-person meet-ups amid the pandemic. If you’ve noticed your eyes feeling the strain of social distancing, you’re not alone. As a solution, many people are turning to blue light blocking glasses.
What Are Blue Light Blocking Glasses?
Blue light is the part of the visible light spectrum that has a wavelength between 400 and 450 nanometers. While blue light does occur naturally, we are also exposed to it from the screens of our digital devices such as phones, computers and tablets. Excessive amounts of blue light can cause eye strain and dryness, and it can even have a negative impact on your sleep. Blue light blocking glasses are specially made to filter blue light, helping to mitigate some of these negative effects of increased screen time. Many people who use them report less eye strain or even decreased headaches. They may even help you sleep better – a University of Houston study showed that melatonin increased for people who wore blue light blocking glasses.
Are Blue Light Blocking Glasses Right for Me?
While blue light blocking glasses can be helpful for preventing eye strain, there are other steps you should take to protect your eyes while working at a computer for long periods of time. Use artificial tears to help with dryness, be sure to follow the 20-20-20 rule (every 20 minutes look at something 20 feet away for 20 seconds) and be sure you are not sitting right up close to the screen – 25 inches away is recommended.
