According to the Ministry of Labor, there are about 4 million teleworkers at the moment, to which are added the millions of students who have brought their classrooms to the screens of computers, tablets or cell phones.

For Mauricio Castro González, coordinator of Optometry at the CES University, this virtual adaptation of working at home can affect the eyes, where 85% of the information we receive from abroad arrives.

“At this time, students and workers have longer periods of exposure to electronic devices, and there is an increase in the information that reaches the eyes in this way. Impairments to the visual system can manifest as fatigue, burning, tiredness, blurred vision or headache ”he explained.

The coordinator Mauricio Castro added that some of these symptoms are caused by the peculiarities of the vision before the screen. For example: exposure for long periods to blue light, which is produced by mobile devices such as cell phones, and which can cause damage to the retina that degenerate into myopia.

In addition, being in front of a device screen produces less blinking or incomplete blinking (the eye does not close completely), which decreases the lubrication of the eye and generates irritation and visual fatigue. Also closeness to the screen, less than 40 cm, can generate strabismus (deviation of the visual line of the eye).

Some advices

- Take 15 to 20 minute breaks from work or study to look into the distance. That makes the visual system rest from permanent contact with the screen.

- Full and frequent blink, it is recommended that it be 15 to 20 blinks per minute.

- Not having the device screen at a distance less than 40 cm. and that the device is inclined downwards with respect to our posture, thus avoiding strabismus.

- Have an annual optometry review to diagnose possible affectations or treat those that already exist.
