The eye is one of the most complex — and most delicate — parts of the entire body. As such, it requires especially attentive care to keep it healthy.
Aside from the obvious steps, like seeing an eye doctor once a year, properly using corrective lenses if necessary, eating lots of foods rich in vitamin A, and wearing sunglasses that block all UV radiation, an important but sometimes-overlooked component of eye care is paying attention to the light emitted by your favorite backlit devices.
What is Blue Light?
The term has become common enough that people are starting to associate it with eyestrain (and other ill effects) caused by heavy electronics use. This doesn't mean that blue light is inherently a bad thing; the sun is a natural source of blue light. Its wavelength on the visible spectrum is what lets our bodies know we need to be awake. The absence of blue light, which no longer occurs naturally after the sun goes down, reinforces the timing function of the pineal gland — the part of the brain that regulates our cycles of wakefulness and sleepiness.
Unfortunately for our beauty rest, the screens we enjoy so much during our downtime (which usually occurs after sunset) also emit the blue light that keeps us alert. That is, it keeps us as alert as we can be after a long, tiring day, when our bodies want to shut down but any blue light we see inhibits that process. Not only is this harmful to our overall health, it wears our eyes out. For those of us in professions or educational environments that require us to spend most of our time looking at a screen, the prolonged blue light exposure we face during the day can also erode our eye health.
How Do You Reduce Damage Caused by Blue Light?
Now that the deleterious effects of too much artificial blue light are becoming more widely known, tech developers have come up with new ways to promote eye health with the way they design their devices. Pulse Width Modulation, which controls the bursts of energy that power electronics, helps mitigate the problem of blue-light flicker and was initially touted as better for viewers' eyes, but it still contributes to eye fatigue after prolonged screen time. A ZeroFlicker™ display is a better choice for the wellbeing of your eyes. Interfaces that resist the growth of surface bacteria also help safeguard your eye health by ensuring that the images you view are clear, not muddled by cloudy film.
Since pain is often a natural indicator that something you're doing is harmful, the comfort that results from embracing ZeroFlicker™ technology should speak for itself. Your eyes will feel better if you go the extra mile to care for them, so add low blue light emission to your list of specs to check the next time you're in the market for any of your IFP or monitor needs. Investing in the health of your eyes always pays off.
