Since Black Friday and Cyber Monday just passed, I’m sure you all have new electronics to enjoy. This brings up the topic of technology and health, or eyesight to be specific. Technology and its effect on health is a hot topic. I mean… there’s an entire day dedicated to online shopping. Technology can certainly do amazing things, but with the amount of time people spend in front of the screen, it does have an impact.
Digital devices and looking into a screen can cause eye strain, which can cause physical discomfort. This occurs after about two hours of looking at screens. A good rule of thumb is the 20-20-20 rule. This is the concept of spending 20 seconds looking at something 20 feet away every 20 minutes of screen time. Increasing text size or boldness on the phone can also help ease eye strain. I understand that nobody wants to have large text on their phone; it can make them feel old. However, this is beneficial for individuals of all ages. Some phones can have the text adjusted to be bold. This can help with easy reading without too large of text.
You might be wondering, what about blue light glasses? Well, there is no scientific proof that this is beneficial, but the majority of people who try them claim they help with eye strain and dryness. This might be a placebo effect or the glasses cause people to blink more. Either way, this could be something you try out if eye strain has been limiting you. Moisturizing the eyes with saline eye drops can also help.
I try to limit my overall time looking at screens and take breaks often. Going for a walk is one of the best ways I rest my eyes while exercising!
