The monitors are getting bigger, and we are sitting equidistant from them. Regardless of the technological progress and the protection that is placed on these same monitors, it is wise to think about special glasses for working on the computer.
Glasses prevent the flow of “blue light” (blue light) to the eye and because of this it is much more relaxed.
People who do office work in front of a monitor spend 1700 hours a year. And that’s only when they’re at workwhich means that the time spent hanging out with the computer at home is also added to that.
The relationship between the wavelength of light rays and the amount of energy they contain is inversely proportional. Therefore, light rays with longer wavelengths contain less energy. And vice versa. Rays at the red end of the light spectrum have longer wavelengths, which means less energy. The rays at the blue end have shorter wavelengths (more energy). Blue light contributes to digital eye strain and glasses that block blue light can contribute to the comfort of computer work.
Numerically speaking, a third of the total light is considered blue light.
Exposure to blue light during the day normally helps maintain the health of this rhythm, but excessive exposure to blue light in the late hours disrupts this cycle and potentially causes sleepless nights and daytime fatigue.
Special blue light blocking glasses are available without any prescription. If you are farsighted and normally wear bifocal or progressive lenses, the use of these glasses, with a prescription, expands the field of vision and clarifies the image on the computer.
It should be noted that this type of glasses is made exclusively for objects that are arm’s length away and must not be worn while driving or similar activities.
If you still don’t want glasses, because none of them are cheap, the 20-20-20 rule should be followed. So, every 20 minutes you should look at an object twenty meters away for 20 seconds. This can prevent excessive eye strain and make it more rested.
