You may have noticed that the blue light coming from the screen is tiring our eyes while using a mobile phone, tablet or computer for a long time. Can we prevent the damage caused by these devices to our eyes by using the "blue light filter" we encounter in our technological products?
Blue light is one of the lights with the highest frequency in the visible light spectrum, and its high frequency means that the energy it carries is high. Our eyes have very sensitive photoreceptors, nerve cells. These cells and receptors can tire when exposed to intense blue light. The blue light filter prevents high frequency light waves that directly reach our eyes. It is possible to use it as a filter in eyeglass lenses as well as in the hardware features of technological products.
In a study conducted at the University of Toledo, the effect of laptop, tablet and mobile phone screens on the eye was investigated. According to the result of the research; This bright light can affect the viewing angle and cause venom production in the light-sensitive cells of the eye. It is also stated in the research report that screen light can also trigger many eye diseases.
In the study, poison production and deterioration were observed in light-sensitive cells exposed to a certain intensity of blue light. Such impairments can lay the groundwork for diseases such as macular degeneration that can result in blindness. The researchers say the blue light filters cell phone manufacturers have used in recent years will work.
