Use phone when lying by side can cause strabismus?

"You have one unread message!" Many people use their phones to process messages before bed. Some people like to use their cell phones while lying in bed, often on their side. Do you have this habit? Don't do it again! This will greatly increase your chances of developing strabismus. And in addition to potentially causing an increase in myopia, lying on your side and playing with your phone can lead to many other injuries.

The dangers of using a cell phone while lying on your side

When we look at a screen, the ciliary muscle is working hard. The ciliary muscle is a circular muscle inside the eye that changes the shape of the lens, much like a photographer adjusting the focus of a camera so we can see things far away or up close. When we look away, the ciliary muscle relaxes and the lens flattens out. When we look close, such as at a cell phone screen, the ciliary muscle must exert force to make the lens convex. If we look at something close up for too long, the ciliary muscle stays tense and it becomes less able to regulate.

When we lie down to play with our cell phones, our eyes exert unbalanced force, which can lead to eyestrain and temporary unilateral vision. Our eyesight can also become distorted to the left and right. In addition, poor habits make our eyes adjust inward, which can cause sudden strabismus. Lying on the side puts more pressure on our spines, which can cause scoliosis. The muscles in our lower back and back can also be prone to pain.

The correct posture of playing cell phone

Pay attention to the distance between the screen and your eyes. Avoid getting too close to the screen, doctors recommend keeping a distance of about 50cm to 70cm.

Be aware of the duration of cell phone use. Studies have shown that about ninety-three out of one hundred people experience eye discomfort after one hour of continuous cell phone use. Therefore, we should avoid using cell phones for long periods of time. It is better to look away or close your eyes for 20 seconds every twenty minutes to take a break. Meanwhile, blinking more often can keep your eyes moist. In addition, try to limit the total duration of mobile phone use to four hours per day.

Keep the room bright. When using your phone, make sure your surroundings are well lit, and adjust the brightness of your phone screen to match your surroundings - too bright or too dark can cause eye strain. This is especially important at night. If you don't want the light to interfere with your rest, you can place a small lamp near your bed.
