Blink, Donít Squint

According to Ohio State University researchers, those who squint their eyes, blink their eyelids less than normal; from around 15 blinks per minute to 7.5. Squinting is common during computer use and reading as it allows things to become visually clearer and reduce any glare. However, squinting results in less blinking that can cause the eyes to dry, resulting in aching, burning, stinging eye symptoms. A good idea is to rest your eyes often and to consider increasing your monitor size, or, reducing your monitor resolution settings which in turn increases the size of fonts and images on your computer screen making you less likely to squint and thus, less likely to suffer from aching, burning, stinging eyes.
