Although the name may be misleading, visual hygiene does not refer to proper eye cleaning. This medical term refers to simple basic rules for keeping factors that can damage vision under control.
In other words, visual hygiene is about adopting specific habits to protect your eyesight. For example, the correct distance between the eyes and a book or screen when reading. It is also called visual ergonomics.
These visual hygiene rules have become extremely necessary nowadays. We spend almost all our days in front of the mobile phone and computer screen, both for work and for habit.
This negatively affects our vision, and it is no coincidence that most people wear glasses. In other cases, you suffer from eye fatigue, nearsightedness or other.
In this article we explain what visual hygiene consists of and the simple rules that can help prevent or reduce vision problems.
Visual hygiene rules for the workplace
Nowadays, most jobs rely on being in an office in front of a computer screen. In recent times, due to the increase in smart working and distance learning, this situation has significantly increased. Similarly, from an early age, children spend hours and hours in front of a book or a tablet.
This means that, during all those hours, we are continually straining our eyesight. Furthermore, we often don’t even pay attention to our posture, nor do we allow our eyes to rest. All of this can end up damaging our eyesight.
Give some relief to the eyes
Visual hygiene proposes a series of very simple rules when reading or writing. If you apply it, over time you will notice that at the end of the day your eyes will no longer bother so much. Vision could even improve. Some of these standards are:
- Pay attention to posture. It is especially important for children. The ideal is to sit in a suitable chair and with a straight back. The feet must touch the floor and avoid bending over.
- This first rule brings us to the second: you have to choose the right place to work. It is important that the chair and desk we use allow us to be comfortable. Experts recommend a chair with adjustable height and a desk that can be tilted according to our preferences.
- Adjust the correct lighting. Working in low light means that we have to strain the eyes, while a very strong light can irritate them. We need to use lighting that does not directly strike the eyes and does not cause reflections on the paper or screen.
Other guidelines for visual hygiene
Proper visual hygiene involves breaks. Resting while working or studying is absolutely necessary. It allows the mind to improve its performance, and so does the eyes.
When we look at a nearby object for a long time, our eyes get tired. For this reason, it is always recommended that, every half hour of work, you spend a short time, even if it is only a minute, to rest your eyes.
On the other hand, another important factor in visual hygiene is the distance we set ourselves from what we want to see. For example, in the case of a book or a screen it is advisable to keep a distance more or less like our forearm.
However, all of these guidelines shouldn’t just apply when working. Even simple, everyday activities such as watching television should be checked. In this case, it is especially important to check the proper distance, which should be about seven times the size of the screen.
Visual hygiene includes a series of very simple rules, such as taking care of our posture in front of a book or a computer, which allow us to improve or avoid vision problems.
However, if you have any doubts or vision problems, the most important thing is to always consult an ophthalmologist. The specialist will be in charge of evaluating your vision correctly and will give you some specific advice on what is best for your case.
