What are the consequences of watching too much television?

Visual impairment is a condition that afflicts millions of people around the world, who face problems perceiving objects and people clearly, or who have completely lost their sight.

These complications, according to the World Health Organization, could have been avoided, at least in half of the cases, by taking care of ocular health and the prompt treatment of conditions that deteriorate it.

In this regard, there is research that aims to demonstrate the link that continuous exposure to screens would have with the development of visual conditions that can gradually alter vision.

According to the Dos farma portal, The constant use of technological devices, such as computers, cell phones and other mobile devices, is associated with straining the eyes, which have to strain to filter the amount of light they receive from screens each day.

This eye strain can be identified by the appearance of various discomforts, such as itching, dryness and irritation.

Experts warn of this risk factor for the development of visual impairments, who recognize that these devices, such as television, have become part of everyday life and that people spend several hours a day in front of screens, whether for leisure , work or studies.

But how bad could exposure to screen light be?

More than one will have been told in childhood that it is bad to watch television so closely, because it can harm the health of the eyes. However, as Clínica Baviera points out, in their blog specializing in vision, there is not enough evidence to link the onset of visual impairment to this habit of spending hours in front of the television.

As they explain, the warning came from a technical failure that some televisions had in the sixties and which could put people in danger, since they could come into direct contact with the X-rays emitted by the screen. However, this factory error is not a problem that persists today.

Although the relationship between screen exposure and certain vision-impairing diseases needs to continue to be studied, what is undeniable is that this excessive use can indeed exhaust the eyes and cause uncomfortable ailments, such as blurred vision and headaches. These are consequences that can be mitigated after a few hours, without representing an irreversible impairment of visual capacity.

Ophthalmology specialist Mauricio Casanovas, consulted by the Top Doctors platform from Spain, points out that the uninterrupted exposure to screens has led to the grouping of the symptoms experienced by people under the name of Display Screen Syndrome.

According to the Rubí Eye Clinic, this condition describes the discomfort caused by using electronic devices for prolonged periods of time. Among them, eye redness, eye fatigue, dry eyeball, tearing and double or blurry vision are listed.

To avoid the appearance of these symptoms, it is advisable to put into practice some basic recommendations in terms of care, such as resting your vision after a long period in front of the screen. This trick is known as the 20-20-20 rule, which involves pausing every 20 minutes, looking at a point 20 feet away for 20 seconds.

It must be said that in case of difficulty with vision, it is suggested to consult specialists and determine if some type of visual repair is necessary, such as formulated lenses (glasses or contact lenses).
