In multiple studies, doctors have found a strong correlation between the usage of the phone and vision defects in the children.
Doctors at Chonnam National University Hospital in Seoul have identified a link between over-use of mobile phones and convergent strabismus, a condition that sees a patient's eyes gradually moving inwards until the person is eventually cross-eyed.
The doctors were able to reverse the effects in nine of the children by banning them from using mobile phones for around two months, a result that they claim proves the link.
In another study done by PGIMER, they found that Children using mobile phones for over four hours a day develop squint and double vision. The study report was published in Neuro-Ophthalmology, an international journal, recently.
The study observed three kids who came to the hospital with affected vision. Doctors found two of them had a summer break at school and were excessively using smartphone for four hours a day in the preceding month.
They found that on stopping the use of mobile phones, these children recovered completely.
The smartphone usage was discouraged and the kids were prescribed cyclopentolate drops to be administered twice a day for two weeks. At the first follow-up, both the patients were recovering and hence, were kept on the same medication. When symptoms subsided, the drops were tapered and then finally stopped. In addition, doctors gave them photochromatic glasses for outdoor use and prohibited the use of smartphone.
Based on the experience of the above cases, the third patient, who had symptoms only for one week, was discouraged from using smartphone and given placebo drops. In a week, symptoms started decreasing and hence, no medicine was prescribed.
All three patients recovered in a period ranging from three to eight weeks. Patients were symptom-free at the final follow-up of six months, added the report of the study.
“We blame the use of smartphones for accommodative spasm. This is because of a positive and reliable history of cellphone usage and the third patient getting relieved of symptoms without medication. Smartphone usage is a representative of near work. Our cellphone dependence is increasing day by day. In addition, children are influenced by parents using smartphones. Nearly one-fourth of the young population is addicted to cellphone. In a technology-filled world of ours, “screenagers” should often be cautioned about the development of this symptom,” it added.
