Many studies show that the biggest harm of looking at computer (or phone) screens is blue light. Blue light can damage cells in the eye, especially optical cells, and can lead to problems such as an increased risk of diseases such as increased damage to eye cells, impaired vision power management and reduced sensory quality.
So if you are constantly exposed to blue light, use protective glasses or turn off devices that send blue light for long periods of time. If you feel your eyes are dry or have any discomfort, visit your eye doctor for advice and examination.
To keep our eyes in good condition, we should give our eyes a break every 20-30 minutes while looking at the computer screen. During breaks, use your eyes to look around the room or let your eyes relax and focus on a distant point or move your eyes to relieve stress.
In addition, there are also some other measures to keep your eyes in good condition when looking at the computer screen, including:
– Use tinted protective glasses or good anti-colored light glasses
– Place the computer screen in a position suitable for the distance from the eyes and the viewing angle
– Use decorative lights or light sensors to automatically adjust the brightness of your computer screen
– Keep the distance from the computer screen to the eyes large enough and avoid looking at the computer screen for a long time without resting.
