Vision Fluctuations at work? It may be Dry Eye!

December 14, 2019

Have you ever been at work, plugging away at your computer and all of a sudden you find your vision blurs? You rub your eyes, blink forcefully, or look away from the screen and then the vision clears. Why is that? What has happened? Your glasses didn’t just change. Your contacts didn’t change. Heck, you may not even need glasses, but the vision definitely changed!

Well, your eyes are drying out.

Our eyes have a natural tear layer that coats them. Every time we blink, new tears are spread across the front surface of our eyes, renewing the layer of tears. If the tears on the front surface of our eyes decrease in thickness, or if the tears are a poor quality, then our eyes become dry and irritated and out vision fluctuates.

Great. So what. How does this apply to work?

Well, all of us (no matter who you are) when we look at things up close, we all naturally stare a little more, and don’t blink as much. So our tears are not being refreshed as they should and the tears on the front surface of our eyes are a poorer quality. Our eyes are drying out and this causes our vision to fluctuate.

This is usually not something we notice at the beginning of the day. At that time our eyes are fresh and the tear layer is good. But as the day wears on and we are blinking less and less, the eyes get more dry and the vision fluctuates. That’s why you feel like you can’t hardly see the computer at the end of the day.

So the next time that you are looking at spread sheets and the numbers start to blur. Or you can’t pick out the details on the project you are editing. Don’t blame your glasses. It’s your eyes drying out.
