Digital Eye Strain
Eye Strain Treatment
So what’s the simplest option in reducing the prevalence of eye strain and dry eyes? Is it to eliminate the use of digital devices? That’s nearly like saying the simplest way to eliminate obesity is by stopping all eating. Obviously this is not the solution.
So what is?
4 Things to consider
BLUE LIGHT TOXICITY and the eye
Whether it be our downlights at home or our computer screens, we are now bombarded by Light Emitting Diode (LED) technology. Typically LED light has significant blue light in its spectrum, which in turn has been linked with eye cell death and potentially macular degeneration. Use Blue Light filters in any spectacles that we wear to view our digital devices. The best “blue filter” currently seems to be PREVENCIA by Essilor.
LACK OF BLINKING and Dry Eyes
Dry eyes from lack of blinking properly is now an epidemic. It sounds like a fairly simple problem but we can assure you we see many patients that are debilitated from this problem. To reduce the risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the “20-20-20 rule.” Looking far away relaxes the focusing muscle inside the eye to reduce fatigue.
PROXIMITY TO OUR EYES and Eye Strain
Digital devices by default are viewed at very close distances to our eyes. This does two things; it strains our eye muscles similar to straining any muscle from overuse and just as importantly the closer we view these devices the more intense the light that penetrates into our eyes.
CONSIDER CUSTOMISED COMPUTER EYE WEAR
Often our eyes do not focus as accurately as they could. In normal circumstances it is not a big problem, but when it comes to looking at a computer screen all day, it is a different story. Imagine carrying a brick in your hand. If this is done for a small amount of time you can do it, but if it means carrying it all day, the day can quickly become miserable. Looking at a computer screen all day with non perfect vision can cause a similar type of fatigue.
For the greatest comfort at your computer, you might benefit from a pair of glasses that has customized computer lenses. This is especially true if you normally wear contact lenses, which may become dry and uncomfortable during sustained computer work.
Computer glasses also are a good choice if you wear bifocals or progressive lenses because these lenses generally are not optimal for the distance to your computer screen.
