You are most likely reading this on a computer, laptop, smartphone or tablet. It’s hard to avoid using a digital device these days. In fact, Albertans spend an average of 10.5 hours a day on a digital device, which is resulting in more cases of digital eye strain.
Digital eye strain is caused by a combination of factors including:
- Eye muscles working harder. When you look at close-up objects such as the screen of a tablet or cell phone, your eyes contract and converge. This causes the eye muscles to work harder, causing them to become strained and tired over time.
- More blue light entering the eye. Digital devices emit high energy visible light, also known as blue light, which can penetrate deep into the eye.
- Less blinking. When we look at a screen, we tend to stare and not blink as often. Fewer blinks means fewer opportunities for your eyes to be coated with a protective lubricant that helps provide relief.
