Smartphones were recently named one of the most important inventions of the 21st Century and they have changed how we live our lives in countless ways.
However, a new report suggests that there may be unsettling health consequences linked to excessive smartphone use: temporary blindness.
Two women, aged 22 and 44, reported recurring episodes of blindness lasting up to 15 minutes.
After countless MRIs, heart scans and other medical tests proved inconclusive, doctors began digging into the patients’ history. What they found blew the case wide open, so to speak.
The doctors were able to link their temporary blindness to cell phone use before bed.
An article in the New England Journal of Medicine sheds some light on exactly how nighttime cell phone use causes the condition.
Both women checked their phones while lying on their side – as many people do. This position leads to one eye being focused on the screen while the other is fully or partially blocked by the pillow.
Thus, one eye adapts to the light from the phone while the other adjusts to the dark. When the cell phone is switched off, the brain gets confused and wonders why one eye is adjusted for “daytime” while the other is adjusted for night.
It’s a recipe for temporary blindness and eventually, permanent eye damage.
What's worst is that the damage goes beyond our eyes as it confirmed that blue light has a connection to cancer, diabetes, heart disease and obesity.
