The first cases of transitory blindness in humans by use of mobile telephones (smartphones)

The first cases of transitory blindness in humans by use of mobile telephones (smartphones)

A recent case published in The New England Journal of Medicine (Medical journal, a publication by the Massachusetts Medical Society) states that one day a patient suddenly notices loss of vision completely and starts seeing again 20 minutes later. This would be an astounding experience for anyone! Of course, it is terrifying and we don’t want anyone to go through such an ordeal. This almost seems like a case straight out of Essays of Blindness, by Nobel Prize winner José Saramago. What the New England Journal publication alerts us is that this is what happened to several patients between the ages of 22 and 40. In one case, one patient, when visiting his specialist everything seemed normal, there were no noticeable disorders however, these symptoms kept occurring for the next six months to the point that, after countless tests, the doctors focused on analyzing the patient’s behavior. Then, they discovered that the culprit creating the problem was the use of patient’s mobile phone used at night.

The researchers were so surprised by the effects of mobile phones and, according to the research ethics committee, two of the authors decided to become test subjects to see if a similar problem was replicated in them. Their mission was to use their mobile phones exactly like the patient and to re-verify that at first they had deterioration and later loss of vision which they confirmed.

Since September 2013, Reticare has made a great effort to transmit health risks (especially for our eyes) caused by the light emitted from screens. The three main risks detected during these years are the following:

- The risks of irreversible damage to the retina and its relationship with macular degeneration or central blindness.

- The problems related to sleep disorders and the reduction in the production of melatonin.

- Computer Vision Syndrome (CVS) or the group of ocular symptoms such as transient myopia, eye fatigue, dry and irritated eyes, blurred vision, photophobia and other symptoms suffered by more than 80% of screen users.

In case the above findings are not sufficient enough to take urgent protection measures, in recent days a new risk has come to light that have been already detected in several patients: The ability of smartphones to produce transient blindness.

What is Transient Blindness? Loss of vision from 5 to 20 minutes that occur in women aged 22 to 40 years repeatedly for 6 months which doctors have not been able to detect at first. When studying the behavior of patients, transient blindness was related to the use of mobile phones at night. (Transient Smartphone "Blindness" N Engl J Med 2016; 374: 2502-2504June 23, 2016DOI: 10.1056 / NEJMc1514294).

This new problem, recently reported by one of the highly reputable journals of medicine and doctors, once again, affects the immediate need to reduce high energy light and the tremendous responsibility we have, especially for the care of our children’s eyes.
