iPads too can contribute to “computer vision syndrome”, a set of eye problems caused by staring at a screen for long periods of time without taking a break. The symptoms of computer vision syndrome include eyestrain, headaches, blurred vision and dry eyes.
People who spend two or more continuous hours in front of a computer or digital media each day are most at risk for computer vision syndrome.
Computer, tablet, IPad and smartphone screens are typically held close, which causes eye strain. These screens always show pixilated images, which cause our eyes to shift in and out of focus without us even realizing it. That weakens the eye’s focusing muscles, causing the eyes to work hard to maintain focus.
People forget to blink when they stare so closely at these screens, which can lead to dry eyes and irritation. A normal blink rate is a few times every few seconds, but when staring at a screen, the rate drops to a few blinks per few minutes.
