Nowadays most of the people using smartphones. Smartphone provides more benefits at the same time smart overuse may damage your eyes. Smartphones, Laptops, and e-readers all transmit blue light which is toxic to specialized cells known as photoreceptors located in the retina, and responsible for our vision. Results of new research now point to a specific way in which blue light emitted from electronic devices has the potential to lead to macular degeneration, a major cause of vision loss. Retinal produced by blue light is toxic to cells. The shorter wavelength of blue light measured to other types of light, packs greater energy, generating retinal which is toxic to photoreceptor cells in the retina. Macular degeneration results from the death of specialized photoreceptor cells in the retina, so critical for vision. Smartphone misuse could contribute to serious eye diseases such as glaucoma, macular degeneration and Retinal Diseases. Eye strain from improper smartphone habits creates unnecessary suffering. Night time smartphone use leads to poor sleep. And also causes to eye strain eyes feel dry, itchy, or stinging, blurred vision, headache, neck, or shoulder pain, seeing double, trouble concentrating, and fatigue.
Photoreceptor cells are vital to our vision by capturing visual images in the world and transmitting them to our brain via a compound known as retinal. Retinal is produced by our eyes and is reacted by the blue light which leads to a number of chemical reactions. But it turns out that some of these reactions lead to toxic radicals which can permanently damage these photoreceptor cells, leading to cell death. Once they are gone, they cannot regenerate. Blue lite exposed other types of cell cancer, cardiac and neuronal diseases. When the retinal-enriched cells were exposed to blue light, the end result was also cell death.
However, there is much you can do to prevent problems from smartphones. Finally one suggestion for all the people how to use smartphones without damaging your eyes. For example, preserve the phone farther away from your face is better. Your phone has a built-in report about your usage. Additionally, you can teach loved one’s habits that help preserve healthy vision.
