Avoiding Eye Strain

We have many senses. They are how we interact with the world. Our first learning experiences are through touch. As time goes on, other senses develop. We hear, we smell, we taste, we develop Proprioception (our sense of how the different parts of our bodies relate spatially to each other and how our body relates to the world around us). And we see.

Our eyes are marvelous instruments. More than the other sense, vision is learned. If a person is given prism glasses that make him or her see the world upside down, over a day or two the eyes relearn how to see – and the world is right side up. When the glasses are taken away, the world is upside down again until the eye receptor / brain connection re-sets and the world is back the way it started.

Eyes at Work


We look at our computers for hours a day. Even if part of it seems relaxing (playing solitaire, minesweeper or such), as long as we’re on the computer our eye muscles are working out.

The eye has many sets of muscles. They are matched on each eye, top to bottom and right to left. Large muscles move the eye in the socket and control blinking. Small muscles control pupil size. There is even a surface muscle that completely encircles the eye.

We tend to take our vision for granted. Every time your eyes move or you re-focus these muscles are involved. They must coordinate, not only each eye individually, but the two have to work together. Like every other muscle in your body, they can become overtired.

Generally, we don’t feel our eyes tire. Sometimes, we do. We may give them a break for a second or two. But ocular stress, just like any other muscle stress, can build up over time.

It Pays to Give Attention to your Eyes on a Regular Basis.


If you work all or most of the day at a computer, here are some tips to help those overworked muscles recover.
