Most internet users have switched from PC to cell phones because mobiles are lightweight devices that easily fit into pockets. You may have been using a PC or mobile device for several years now. Do you know that the color display of your computer and smartphone transmits different invisible rays of various wavelengths (intensity)? Blue light is one of the most harmful rays transmitted by a color monitor. Studies prove that blue light makes reading eBooks or text content during the daytime a great experience. But after the evening, prolonged exposure of blue light to the eyes isn’t good.
Some versions of the Android OS allow users to turn on the auto-brightness feature, which ensures that the display’s brightness is decreased automatically according to the time of the day. You can find this option in the display settings of the Android OS. The major drawback of this setting is that it doesn’t have any impact on the blue light. Because of this limitation, eye experts advise people to limit the use of cell phones during the night. If you want to protect your eyes from intense blue lights transmitted by the mobile’s display, try out one of the below applications:
