Vision for better life. We live in a time where most people spend a significant part of their daily lives in front of computers, mobile phones and other digital devices or screens.
Of course, the benefit from them is multiple, but the damage can be much greater if we do not take into account how and for how long we use what technology has provided us with. Excessive use of computers can affect our health because it causes rheumatic, neurological, eye and other disorders.
We have always been familiar with the harmful effects of UV radiation that negatively affects vision and we tend to buy glasses with UV protection, but few of us know about the harmfulness of blue radiation emitted by digital screens, especially computer monitors.
This radiation borders, exactly, with UV radiation within the EM spectrum, which tells us that it is also harmful in itself because it has a lot of energy.
Research indicates that long-term exposure to this radiation causes pathological changes within the eye that are accumulative in nature, which means that we are not aware of them at first (as well as the immediate consequences of exposure to UV radiation)… and what we are not aware of – we do not attach importance to it. Focusing on the screen image for several hours reduces the frequency of blinking up to 5x, as a result of which rare and incomplete blinking causes dry eyes, a burning sensation, irritation and discomfort due to the evaporation of the tear film.
Also, the destabilization of the tear film is affected by the dryness of the air in offices and closed rooms, which is caused by central heating or air conditioners. Excessive work at the computer causes increased eye strain due to excessive engagement of the eye muscles to maintain focus on close objects, as a result of which some people may have headaches or pain in the forehead, eye or occipital region.
Focusing on the screen is much more difficult than focusing on printed material because the image on the screen consists of tiny dots (pixels) that have a clear center and unclear edges, which requires constant activity of the eye muscles to keep the complete image clear. Poor lighting conditions in work rooms as well as inadequate contrast and tilt settings of the monitor screen contribute to eye strain.
In order to make your work in front of the computer easier and more pleasant, we offer you several tips that you should follow:
USE GLASSES THAT PROTECT YOUR EYES FROM THE HARMFUL RADIATION OF DIGITAL SCREENS
Whether you wear prescription glasses or not, we advise you to use glasses with a so-called blue filter that protects your eyes from the harmful effects of certain blue-violet radiation emitted by computer monitors.

REDUCE THE GLARE FOR BETTER VISION
Glare is a consequence of the reflection of light from bright or polished surfaces such as white walls, windows and the monitor screen itself. If you can, choose rooms with darker wall colors for your work environment.
Place the monitors so that light from windows does not reach them.
ADJUST THE SCREEN BRIGHTNESS ON THE MONITOR
Adjust the monitor so that the contrast between the characters and the screen background is high. Choose the appropriate font size and color for optimal comfort.
OPTIMIZE YOUR WORKING ENVIRONMENT FOR BETTER VISION
Move the monitor screen 50-70 cm away from your eyes and adjust the angle of the screen that suits you. Adjust the height of the chair so that the screen is at eye level. Direct the table lamps, if there are any, so that they do not shine directly at the screen.
BLINK MORE OFTEN TO IMPROVE VISION
(this is very important in order to constantly renew the tear film on the surface of the eye and avoid the feeling of burning, dryness and irritation).
Close your eyes for a few moments every half hour to rest them.
DROP ARTIFICIAL TEARS
Several times while working at the computer to improve the feeling of comfort that is lost by breaking the tear film from the surface of the eye due to less frequent blinking.
PRACTICE EYE EXERCISES
Every half hour, look at distant objects (eg through the window) for twenty seconds to relax the eye muscles, and then alternately look at distant and close objects for ten seconds.
