What is Digital Eye Strain?

Digital eye strain is the fatigue that is caused from using digital devices for long periods of time. Most commonly causing dry eyes, headaches, red eyes, blurry vision and light sensitivity. Digital device use doesn’t only cause strain to our eyes, it can also cause neck and upper back pain which can damage your spine.

There are two main components that contribute to digital eye strain. Over working your eye muscles and exposure to light. The muscles on the inside of your eyes help you focus up close on the computer and while looking at your phone for long periods of time. And like all other muscles in the body, they can get fatigued from over “flexing”, which most commonly causes headaches, strain, and pressure around the eyes.

When staring at any type of digital device, it is essentially like staring at a light source that is also emitting some harmful light. Your eyes are absorbing the light which can cause fatigue from over saturation and “photostress” to the light. For example, when you go to the movie theatre for a matinee, when you’re leaving the movie and exit the theatre your eyes get shocked from the sunlight. It isn’t that drastic, but remember, your computer screen is a light source that’s emitting a large amount of light, and even worse if your computer is situated under fluorescent lighting at the office or if you sit near a window and outdoor light reflects off the screen.

Many people also notice that during the winter months when daylight is reduced, after a long day of work on the computer, while driving home at night, it is more difficult to see. This is due to the photostress and fatigue your eyes are experiencing. Your eyes will take a much longer time to adjust from a well lit environment at your desk, to the darkness outside.

So what can you do about it? Below are some ways to prevent digital eyestrain by relieving your eye muscles of “over-flexing” all day, and to block harmful light from entering your eyes, to make digital devices more comfortable to view.
