It's with you everywhere you go but doctors say if you're not careful, your smartphone could lead to health problems in the future.
When thinking about screen time, it used to be reserved for the office.
However, smartphones and tablets can extend texting, typing and Tweeting beyond office hours.
In fact, some of us use our phones right up until the moment we fall asleep.
Dr. Alan Glazier says without the proper habits, focusing on screens big and small can take a toll on your eyes.
Glazier said, "What do we do when we look at a computer? We don't blink. And we just get so entranced and we're focused that the eyes don't, the regular blink rate is decreased. So by doing that, our eyes start to dry out."
To avoid things like dry eyes and headaches, Glazier reminds patients to take a break.
He said, "Every 20 minutes, take a 20 second break and look 20 feet or further away from you. 20 feet is where your eyes start to relax and by doing that you restore a lot of the focus strain that might be contributing to the headaches, the strain and/or the dry eyes."
Glazier also recommends discussing digital habits with your eye doctor, just in case adjustments need to be made.
Experts suggest avoiding the mindless scrolling through Twitter and limit the usage of your device.
They also suggest keeping mobile devices at a safe distance.
The recommended length is at least the distance between your elbow and your wrist.
Also, enlarge fonts if you need to and adjust screen settings, like contrast and brightness to make it easier on your eyes.
