For students, long hours spent in front of the computer go with the territory. Finally, they graduate, and embark on their chosen career – which, for many people, involves even more hours of screen time. At the end of a long day’s work or study, most folks will feel symptoms of mild eye strain, and as we get older, that can turn into a more severe form of eye strain that comes with uncomfortable and worrying symptoms.
“Eye strain from staring at screens is incredibly common,” says Australian behavioural optometrist Jacqueline Gattegno. “It’s believed that most people these days have some degree of digital eye strain, but it will come as a relief to know that there’s no proven link between eye strain and the progression of myopia.”
“At the same time, there’s also no real proof that computers can’t contribute to longer-term vision problems. The jury is out. However, if you’re already experiencing vision issues and do visually intensive work, eye strain is an inevitable result, and if you have perfect vision and make your eyes work too hard, you’re also at risk of experiencing eye strain.”
Symptoms of Eye Strain
Most people will identify with the feeling of having “tired eyes.” They may be dry, and they can be sore and uncomfortable. The dryness of strained eyes can cause a burning sensation, and one may experience sensitivity to bright lights, trouble with focusing and refocusing the eyes, headaches, or even double vision.
“It’s easy to say that digital eye strain among students and professionals isn’t serious,” says Jaqueline, “but symptoms this uncomfortable must be taken seriously because they have such a big impact on quality of life and the ability to fulfil one’s overall potential. Nobody is going to be at their best when they’re battling with discomfort.”
How to Prevent and Treat Eye Strain
“Your optometrist can help,” says Jacqueline. “Even if your glasses are fine for all the other things you do, they might not be suited for seeing at screen-distance. Computer glasses can also be tinted to reduce the effects of blue light. If your eyes are dry, an optometrist can determine whether it’s just a matter of not blinking enough or whether your tear glands aren’t working quite as they should. If the glands are blocked, there are non-invasive treatments, and if it’s just dryness from not blinking enough, there are drops that can help with dry eyes.”
“Since the overtired muscles that focus your eyes have a big role to play in eye strain, giving them some stretching exercises can work wonders. Behavioural optometrists are able to teach you eye exercises that will help to relax and strengthen the muscles in your eyes.”
Taking frequent breaks requires almost as much discipline as working or studying for hours, but despite sounding counter-productive, it’s quite the opposite. “Give your eyes and your brain a break every twenty minutes or so,” says Jacqueline. “Chances are, you’ll get even more done. Just twenty seconds looking at a distant object every twenty minutes can make a huge difference.”
You should also blink consciously. “When people work in front of screens, their eyes are fixed on the task, and they blink less often than they should. That dries out the eyes and accounts for the burning, gritty sensation that people with eye strain experience.”
According to Jacqueline, a person’s computer, their posture, and the layout of their work area may also contribute to their eye strain.
“Always work with your screen at arms’ length from your face and positioned so that you look slightly downwards at it when seated in an upright posture. Making text larger may help, as can increasing the refresh rate of your screen to reduce flickering. You can also reduce glare by using a matte filter for your screen. Ensure that your workspace is well-lit and that your screen is not brighter than the light in the room. If dry air is contributing to the problem, a humidifier may be of help. Finally, make sure you’re getting enough sleep. It rests the eyes and re-energises the mind.”
