Description: Caring for the eyes of the computer screen is an increasingly known concern on the part of everyone. Taking care of the view of the screens is something that began years ago with the development of auxiliary screens that overlap on the monitors of the old computers. Currently, your eyes are exposed to the blue light emitted not only by computer monitors but by devices such as mobile phones or tablets. The number of hours you spend in front of devices that emit blue light increases, not because you spend more time in front of the computer, but because you are more exposed to blue light, in intermittent periods, between all the different devices.
The use of blue light protecting glasses constantly protects you from the harmful properties of the light of the screens.
The Advantages of Wearing Glasses that Block Blue Light at Night
The benefits of the glasses that block blue light are immense and varied. The use of these glasses for a week caused surprising results among people with bipolar disorders. People who used blue light protecting glasses that block the light between 6 pm-8 pm for seven days had a marked improvement in mania symptoms compared to those who wore clear glasses. What’s more, the improvements began just after three nights of use.
The dramatic results make sense given the relatively recent discovery of intrinsically photosensitive retinal ganglion cells, which are receptors in their eyes that detect only blue light. These receptors communicate with the areas of your brain that are related to controlling your biological clock (hypothalamus), as well as your mood and emotions (the limbic system). Research also found dramatic improvements in insomnia and mood in approximately half of the bipolar patients wearing blue light blocking glasses.
The disadvantages of having blue light protecting computer glasses:
- The glasses with blue light filters change the color of everything you see in the yellow tint. This often causes difficulties to read the screens.
- The light blue glasses increase the number of complaints of scotopic vision loss.
- It also raised concerns about changing the perception of colors.
- The blue light glasses could not protect skin containing also melanopsin, the photoreceptor that warns your body to warn you if it is day or night.
Therefore, melanopsin or light blue glasses cause sleep disturbances.
