Temporäre Erblindung durch Mobile Phones


Neues Phänomen: Nächtliches, einäugiges Checken der Feeds im Bett (mit einem Auge aufm Kissen und einem offen auf den Screen schauend) kann zu temporärer Erblindung auf einem Auge führen. Die Erklärung ist einfach: Das Screen-Auge muss sich an die Dunkelheit gewöhnen, das andere nicht.

In Thursday’s New England Journal of Medicine, doctors detailed the cases of the two women, ages 22 and 40, who experienced “transient [flüchtige] smartphone blindness” for months. […]

He explained that both women typically looked at their smartphones with only one eye while resting on their side in bed in the dark — their other eye was covered by the pillow. “So you have one eye adapted to the light because it’s looking at the phone and the other eye is adapted to the dark,” he said.

When they put their phone down, they couldn’t see with the phone eye. That’s because “it’s taking many minutes to catch up to the other eye that’s adapted to the dark,” Plant said.

Neues Phänomen 2: Obsessiv-Compulsive Disorder und Nomophobia (No-Mobile-Phone-Phobia) in Verbindung mit Mouches Voulantes (Floater, das Zeugs in Euren Augen, die Würmerdinger, die durchs Sichtfeld schwimmen) macht riesige schwarze Flecken: The Black Spot.

If nomophobia is more or less normal, how does one distinguish it from a pathological obsession? For clinicians like me, the true test of whether mental illness is present is the degree to which the individual's daily life is impaired. In Eric's case, there was no question. Before the floater had appeared, he said he had been glued to his smartphone night and day and could hardly pry himself away to study, eat and sleep. When the floater appeared, he switched his obsessions and compulsions to that black spot.

Eric had all the symptoms to make a diagnosis of obsessive-compulsive disorder (OCD), according to the DSM-5—the Diagnostic and Statistical Manual of Mental Disorders. The fact that his obsession with his cell phone was almost typical behavior for his generation had essentially masked his disorder.
