This is true. When a new gadget is launched we often neglect the damaging consequences it may have on us and just focus on its amazing new features. We have long known that our laptops, Phones, Tablets are harmful, but this revolutionary study might just change your perception on your device.
Blue light from our phones tablets and computers is not healthy. Many studies have already confirmed that negatively impacts the Circadian Retina which causes sleep issues. Lack of sleep could lead to many other health problems. A new study published in the journal 'nature' tells us that the blue light coming from these devices make one's eyes attack itself. This in long-term could cause the degenerative disease that causes one to go blind. We can spend hours on devices not knowing that; that day could be one of the causes as to why we will be blind and the future. A group of researchers at the University of Toledo why this happens. It was found out that with "disease occurs when cells behind the light-sensitive tissue inside your eyeballs break down resulting in a continual lost our eyesight"(-big think article writer Derek Beres). Blue wavelengths are suspected to be the cause of this, however, this is greatly debated. There is quite some proof that points toward the blue light being the cause which is why it is considered the harmful light. Researcher Ajith Karunarathne says "If you shine a blue light on retinal, the retinal kills photoreceptor cells as the signalling molecule on the membrane dissolves. Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good." To further prove his point he exposed the retinal molecules to cancerous cells, heart cells and neurons and the blue light with the retina killed them all. This was not observed with greed yellow or red light. Karunarathne claims that blue light from our phones is mildly tolerable, but not helpful at all. His team is also studying the effects of tablets, televisions, and computer monitors on the human eye.
With millions of people losing their sight as they grow up this study is extremely important. We must limit our time on these devices or else hey will limit our vision. Technology advances their consequences get harsher and harsher. We must also take into consideration the drawbacks of these devices and use them carefully.
