Will my eyes be affected if I stare at my laptop for a very long time?
When you work at a computer, your eyes have to focus and refocus all the time. They move back and forth as you read. You may have to look down at papers and then back up to type. Your eyes react to images constantly moving and changing, shifting focus, sending rapidly varying images to the brain. All these jobs require a lot of effort from your eye muscles. And to make things worse, unlike a book or piece of paper, the screen adds contrast, flicker, and glare. What’s more, it is proven that we blink far less frequently when using a computer, which causes the eyes to dry out and blur your vision periodically while working.
You’re more likely to have problems if you already have eye trouble, if you need glasses but don’t have them, or if you wear the wrong prescription for computer use.
Sitting too close to your computer screen or holding your cell phone very near to your face could potentially lead to some vision problems. A lot of people don’t realize this, but when you’re viewing something really close, that’s when your eyes are working the hardest—much harder than when you’re looking at something far away. Heavy computer use could turn out to cause some similar eye issues just as close textbook reading.
