Over-dependence on smartphones has its disadvantages, especially when it comes to the health of your eyes. These concerns have been corroborated by various studies in the past. One such example is a study published in BMC Ophthalmology (a leading journal on eye disorders) in October 2016, which claims that people who spend more time on smartphones show more symptoms of dry eyes.
A Spanish study published in January 2017 suggests that constantly looking at the smartphone screen can also cause retinal damage and macular degeneration (a leading cause of blindness). There are ways in which you can mitigate the damaging effect of a smartphone screen. Here are some tips.
Apply blue light filter
Most screens including those in smartphones emit high-energy blue light. It is one of the key sources of eye strain and is considered bad for the retina. Smartphone users can overcome it by switching on the Bluelight filter in the display settings. Most smartphones with custom UI come with some form of Bluelight filter. It works by subduing the display or changing the colour tone so the screen would put less strain on the eyes.
Stick to moderate brightness
Most users keep the brightness level at full for the best experience, while many keep the brightness level too low to enhance battery backup. Both extremes can be harmful. Adjusting the brightness level to moderate and using the auto brightness to adjust the screen brightness according to ambient light is another trick which can help reduce stress on eyes and protect users from sudden glare.
Use special screen protectors
Screen guards can not only protect your smartphone’s screen from scratches and impacts but can also protect your eyes. A lot of screen guards come with non-reflective coating. Applying them also curbs the reflective nature of the screen and puts less stress on users’ eyes, which usually occurs when you are looking at the screen and the light source is right behind or over your head.
Holding a smartphone too close to the face is another factor which can damage eyes and should be avoided. It is hard to put this into practice, though. For better or closer view, users tend to bring the smartphone closer without even realising the damage it can cause. For users who are struggling to find the right distance, there are apps which can warn when the screen is too close to the eyes. Samsung’s Safety Screen is one such app which can help users by blocking the screen every time it finds the face too close to the screen.
