Checking your phone one last time before going to sleep could cause partial blindness. A British ophthalmologist, at the origin of this discovery, has just published his findings in the New England Journal of Medicine.
When your smartphone makes you blind
A British ophthalmologist has just made a discovery, which provides an explanation for a phenomenon that many smartphone addicts have no doubt already experienced. Looking at your phone screen in the dark could lead to partial and temporary blindness. To reach this conclusion, published in the New England Journal of Medicine, Dr. Gordon Plant saw two women aged 22 and 40 for consultation.
These two people had nothing in common except their numerous consultations for symptoms of partial blindness, which the doctors they had encountered so far had failed to explain. Dr Gordon Plant was the first to ask them what they were doing when their blindness started. Question to which they both replied that they had just consulted their phone, lying on their side, in their bed and in the dark, one eye hidden in the pillow, the other fixed on the screen.
Screens are not recommended before sleeping
Here is the explanation, for Dr. Gordon Plant, who notes that in this position ” one eye adapts to the light of the smartphone “When the other” adapts to the dark of the night “, So that” when the phone is dropped, the eye that was looking at it takes several minutes to catch up with its neighbor who got used to the darkness “.
Although these temporary blinds are completely ” harmless “According to Dr Gordon Plant, they are also” easily avoidable », Especially as scientists agree that screens are not recommended before sleeping as they disrupt sleep cycles.
