Despite the many benefits it offers, even technology cuts both ways. Like most everything, technology must be used in moderation, so as not to harm our eyes, among other things.
Often, perhaps unknowingly, when we use technological devices such as mobile phones, tablets, televisions, and computers, we are exposed to blue light which emanates from these devices, light, which, as explained to tvm.com.mt by the doctor and former radiographer Dr Georgiana Farrugia Bonnici, is not good for eyesight.
Dr Farrugia Bonnici provided a number of tips to prevent a screen from harming your eyes:
- The font and level of screen contrast should be such that your eyes do not suffer when looking at your screen.
- Colour temperature of light should be kept low in order that the blue screen light reduces harmful emission
- Give your eyes a rest from the screen every 20 minutes. For every 20 minutes you spend in front of the screen, give yourself a 20 minute break and during that time try to focus on something which is 20 feet away.
- Keep arms lengths distance between your eyes and the screen.
- There are blue light filters which can reduce eye fatigue particularly if you use computers constantly for work purposes. Although, the American Institute of Health has not found any research that concretely claims that permanent damage to the retina can be prevented when using these filters.
Dr. Farrugia Bonnici added that there are artificial lubricants that can help keep your eyes dry. He advised those who have glasses, to undergo an eye sight test regularly.
