Eyes allow people to see the world around them by detecting light. As with everything else, though, too much light can be dangerous for the ocular organs. The Huffington Post has an article published last July 24, 2014 that discusses the negative effects of “blue light” emitted by popular digital devices, as well as eye strain caused by extended periods of using such devices. The report points out that blue light emission from computer and smartphone screens has the “highest energy wavelength of visible light,” which can lead to serious eye damage:
Even though blue light is nothing new, the biggest issue is the amount of blue light exposure that we get each day through digital device use. With this exposure increasing over time, we are actually causing permanent damage to our eyes. But unlike digital eye strain, the effects of blue light are cumulative and can lead to eye diseases like macular degeneration.
Children are especially at risk when it comes to the negative effects of blue light exposure. These days, a lot of homework is done online, and many children have access to (or have their own) digital devices that they are using for increasingly longer periods of time. The difference for children is that their eyes are still developing, and they don’t yet have the protective pigments in their eyes to help filter out some of this harmful blue light.
It is not enough to simply cut down on your digital device usage to prevent diseases like macular degeneration. You should consider visiting a local eye doctor before serious complications develop. A center for eye care in Indianapolis such as Moody Eyes should be able to correctly assess the current condition of your eyes, and prescribe any possible solutions to address your vision problems.
Blue light can aggravate the effects of age-related macular degeneration, and can even cause lasting damage to an individual’s retina, among other effects. Adults who often have to work in front of screens, and even children using tablets and the like, are at high risk of damaging their vision if they stare too long into the screens. If you suspect that blue light is beginning to put a strain on your eyes, consider taking a comprehensive Indianapolis eye exam to determine the state of your eyes. If the damage is apparent, your eye doctor might be able to prescribe you glasses to reduce the amount of blue light that enters your eyes.
