Blue light has become an integral part of our daily lives. With the development of technology and the need to use smartphones, computers, iPads, and other devices that emit this light, it is no longer possible to avoid it completely, and sometimes it has become more like addiction.
However, by following some simple guidelines, we can reduce its harmful effects on our health
What is blue light?
Blue light is part of the visible spectrum of light, has high energy and short wavelength. It is found naturally in sunlight, making it a normal component of everyday life, but exposure from artificial sources such as electronic screens (phones, tablets, computers) and LEDs exposes us to increasing amounts of blue light.
Effects of blue light on health
Unfortunately, there are many negative effects that green light causes on their health, the most notable of which are:
Digital eye strain, also known as computer looking syndrome, results from prolonged exposure to blue light and leads to eye dryness and irritation, along with some cases of blurred vision and headaches.
Sleep disorders: Blue light causes a reduction in the production of the hormone melatonin, which helps regulate sleep, which leads to difficulty sleeping and general body disturbance and leads to a permanent feeling of laziness.
Skin aging, which, although it is an aesthetic problem, greatly affects a person's psychological health. Studies have shown that blue light may contribute to accelerating the oxidation process in skin cells, leading to the appearance of premature wrinkles and skin pigmentation.
Blue light protection
In light of these health problems that blue light causes, there are treatments or prevention methods that you can resort to:
Use glasses equipped with lenses that protect against blue light by blocking it from entering the eyes, even if only partially.
Activate night mode, which is an option offered by most digital devices under the name “night mode” or “night light,” and it works to reduce the emission of blue light.
Apply the 20-20-20 rule, which is a rule that requires resting your eyes while using digital devices. Every 20 minutes, you should stare at something far away for 20 seconds. This habit helps relieve eye strain.
Refrain from using the phone at least one to two hours before bed. You can read a book or do other relaxing activities instead of looking at screens.
