Staring at a phone screen for too long can fatigue the eyes.

Mothers have always warned their kids that sitting too close to the TV can ruin their eyes, but now, the tube is just one piece of the blinding puzzle. According to new research, multiple electronic devices including smartphones, computers, and tablets may be damaging the eyes of tech-loving people everywhere.

You see, numerous electronic devices emit blue violet light. While it can be good for our bodies in regulated amounts, too much exposure can be toxic to our eyeballs and physically lead to blindness. Additionally, staring at bright screens causes us to blink significantly less than normal. Blinking prevents our eyeballs from drying out, and recent studies have found that it gives our brains a chance to organize our thoughts and focus. Finally, overexposure to blue violet light can interfere with our sleep cycles, making it difficult to fall asleep at night and mess with our focus the following morning.

It turns out that many people under the age of 25 check their mobile device around 32 times a day! And, they aren’t just quick glances to check the time or read a text. People spend an average of 7 hours a day with their eyeballs glued to a gadget screen! In that time, they’re much less likely to blink. What’s worse, is that more than 50% of individuals feel anxious when they’re without their phones for too long.

Since smartphone screens are only getting bigger with each new model that’s released, there may be more risk for our vision than meets the eye.
