WARNING: This Thing You Do With Your Smartphones Every Night Could Cause You Blindness!

Advancement in technology is debatably a good thing since it sometimes comes with a price. If we don't use technology with careful measures, it may cause severe damage to our health, including blindness!



A number of studies have shown how smartphones can trigger varying health conditions from addiction to depression to chronic pain. And the latest health consequence associated with excessive smartphone use is temporary blindness.

A report published in the New England Journal of Medicine stated that two women in England were diagnosed with blindness induced by too much smartphone usage, especially at night. Both of the women described that they were having vision difficulties in one eye though the occurrence is temporary.

More about the Condition

The eye problem is known as transient monocular visual loss and the symptoms are as follows:

1.       Only one of the eyes becomes blind.

2.       The vision loss is only temporary, usually lasting only for 15 minutes.

3.       It happens almost at nighttime.

In the case of the two women, they underwent different tests, including cardiovascular exams and MRI scans but there was nothing wrong with them. Then an eye specialist took a look at them and determined the problem was with how they regularly check their smartphones. The two women actually had the same habit of checking:

Ø  Before they went to sleep, they would check their phones.

Ø  They’d do the same thing again right after waking up.

Ø  They would lie on one side and one eye is covered with a pillow or closed, while the other is open to look at their phone.

After this particular mode of checking, both women would experience temporary vision loss in their right eye, which is the eye they used to view their phone. At first, the vision loss would only occur two to three times weekly. But to their horror, it became a daily event. When the women talked about this to the eye specialist in London, he and his colleagues theorized that the blindness is caused by uneven light adjustment that occurs between the phone eye and the pillow eye.

Our eye has the amazing capability to adapt to different levels of light – and can rival any camera. However, when we look with our phone with one eye and the other still in the dark, this can result to “differential bleaching of photopigment,” which then tricks the eye that we use for viewing our phone that it’s gone blind.



Temporary blindness is very scary indeed, but this doesn’t mean we should put our precious phones down. Just like with all other things, we should know how to use them moderately.
