In light is causing many people to lose

In a world revolving around and being propelled by the internet, it is easy to lose touch with the human body. In recent years many health concerns related to the use of computers have popped up, however, often times they are overlooked or out weighed by the importance of technology. In an attempt to improve the health of computer users, companies have marketed all sorts of ergonomic chairs, keyboards, and arm rests; the most pressing concern however, is not posture or hand placement. It is the fact that over exposure to blue light is causing many people to lose their eyesight yet many people still make light of the dangers. Exposure to blue light emitted from computers, TVs, smartphones, and even energy efficient lighting has been proven to cause permanent retinal cell damage. The simple solution to this would be to reduce the amount of screen time, but “it’s too late to break the Facebook and Iphone addictions” (Wishart). Along with the cell phone addicts who are unwilling to unplug, almost all large companies and hospitals are entirely online based. Medical records and company information is all stored in computers and many of the communications between companies are through services such as email. Leaving these technological advancements behind for the sake of our health will not only set us back, but it will also slow all further advancements. Clearly the first solution to come to mind is just not going to happen. We must now look to solutions that will allow for continued use of technology while still protecting our health. Reducing the amount of exposure is a way to reduce the stress put on the eyes and in turn increasing ocular performance. For the Iphone addicts there is a feature called “Night Shift” that increases the warmth of the screen and reduces the amount of blue being emitted. While this is not going to fix all phone related blue light issues, turning it on will positively contribute to the health and well being of the eyes. A study done by Chronobiology International, a peer-reviewed scientific journal that includes biological and medical rhythm research, shows that protective eyewear can be worn to block out blue light to combat the damaging effects (“Shift Work”). These protective glasses have a tint that filters out blue light therefore heavily reducing the amount of blue light entering the eye. This is an easy option for those who already wear glasses because the next time a lense is replaced, they can add the blue light filter. Protective glasses can also be made with no prescription for those who don’t need vision correction. The time it takes to make a visit to the eye doctor is well worth protecting your eyes in the long run. Taking a step away from computer screens and phones, there are other ways to be exposed to blue light such as energy efficient LED light bulbs. “From a technical point of view, use of LED as an illumination source is efficient, because it is energy saving, and long lasting compared to pre-existing light sources, such as incandescent light. However, LEDs are known to emit quite a large amount of blue light” (Lee et.al). We have benefit from these lights in the sense that they save energy, however we have seemed to overlook the dangers to the eye. LED lights emit a large amount of harmful blue light. These lights have become extremely widespread especially in large companies, retail stores, and even many homes. This frequent exposure is a huge problem for the health of our eyes. Studies published in the Environmental Health Perspectives journal have been done to measure the effects of blue light in rats. The environment of the rats’ enclosure was designed to accurately simulate the average person’s exposure to blue light through only light bulbs. In just 9 days damage had already begun to show. If humans do not begin taking preventative measures to protect their vision, imagine a what a lifetime of exposure will do. We cannot eliminate blue light exposure from our lives, however being aware of the dangers will allow for this issue to be recognized and taken more seriously. Word count: 692
