The beginning of the school year means leaving behind long days at the beach or the pool and going back to long hours of books, reading and homework. 80% of the information in class reaches the brain through the eyes, which is why it is essential to pay attention to our eye health. To do this, we must consider a number of "visual hygiene" tips which will allow us to ensure ocular comfort of the smallest of the house.


Proper lighting is extremely important when performing any task. The light should be neither too strong nor too weak and preferably natural. It is advisable to work with a light on the ceiling and one concentrated in the study area, avoiding direct light to the eyes and shadows on paper, as they can produce eyestrain.


The study room should be well ventilated and at normal temperature, avoiding where possible the continuous exposure to heat and air conditioning, which can promote the development of dry eye.

Body position

It is important to adopt a correct posture, which make us not be too close to the book or screen. The height of the chair should allow your feet rest on the floor, keeping your back straight against the backrest without tilting the head and neck.

Working distance

Between the eyes and the paper should be at least a distance similar to that between the elbow and the tip of the index finger, about 35-40 cm approximately.

Using screens

The use of screens does not entail serious risks for eye health but prolonged use itself can cause eyestrain. The screen should be tilted back, and standing about 50-70 cm and at eye level or slightly lower, so as not to overload the eye muscles. In patients with refractive errors associated with the use of their glasses or contact lenses it is necessary when employing any electronic device to minimize eye fatigue. We must also monitor that the child does not to overuse them, as his/her visual system is under development.


When performing tasks requiring looking up close, always take periodic breaks every 35-40 minutes, looking away for a few seconds to relax the focus.

With the emergence of symptoms of eyestrain, such as headaches, eye redness, itching or blurred vision, it is advisable to see a specialist to assess the origin of the condition and indicate the most appropriate treatment in each case.

Taking into account these recommendations, following a varied diet and making eye check-ups, you will ensure proper visual development of the child and correct performance during the school year.
