Smartphone Blindness: Using Phone during night ?

If you are one of those who use their smartphone during night after turning off the lights, then here is something you must read. A new disease of modern world is discovered recently "Smartphone Blindness", where the patient uses smartphone during night after turning off the lights of the room and when he/she wakes up in the morning the eyesight was gone. However mostly it happened as a temporary problem, but nobody would like to experience it. Being blinded without a blindfold is something very scary. If you want to save yourself from this condition then you must read this article.

How eyes adapt between darkness and light

Before we tell you more about this recently discovered Smartphone Blindness, you must have some basic knowledge about how our eye helps us in watching things during day and night time. There are two types of cells in our eye. One is Rod Cells and second are Cone Cells. Cone Cells are responsible for viewing colors and bright things (thats day time vision), while Rod Cells can view better in dark (thats night time). If you are in a completely dark room from sometime and someone turns on the lights suddenly then it takes our eye 5 to 7 minutes to adjust to it, as cone cell in the eye activate themselves for it. But when the opposite thing happens and we go from a well illuminated room to a dark one then it takes 30 to 40 minutes for our eyes to completely adjust and activate Rod cells.


Smartphone Blindness

What we see is a joint output of our eyes and brain. Sometimes our brain works in a strange way, where the researches were not done yet. One such thing is Smartphone Blindness. Using your Smartphone in a dark room for longer duration is perfect condition for this medical condition to happen. Two such cases were reported in "New England Journal of Medicine". Two ladies of age 22 and 40 reported that they suffered from temporary blindness. Doctors tried to find the reason behind that. But to the surprise of doctors the reason was surprising. Both ladies used to work on their phone till late night after turning off the room lights and sometimes their one eye use to remain close due to pillow. Both of them used just one eye to operate their smartphone in a dark room. After finding these facts, scientists tried to find the reason.

The result they found is something new. When we use a smartphone with one eye closed (either by pillow or some other hindrance), then our one eye get adapted to brightness while the other adapt to darkness. Sometimes this thing can mess something in our brain and we can loose our sight for sometime either during night or for few minutes after waking up.

If you want to save yourself from this Smartphone Blindness, then never ever use your phone in a dark room with one eye. Using your phone till late night is itself something unhealthy. It not only disturbs your sleep but also disturbs your biological clock. Now a days mobile phone manufactures are increasing brightness of screens, so that you can use it during a sunny day, but its making extra stress on our eyes. Especially if you don't know how to set the brightness level to low, you are harming your eyes. Even some people who know about the brightness level, don't set it to low as they want to see everything crisp and clear. What such people don't know is that brightness can permanently damage their eyes.

Please use your smartphone with less brightness and use it less during night. Even if you have to use it during night, use both eyes to look at screen, not just one.
