You may be able to hit a fast-moving ball, read words and sentences, and observe data on a computer screen without difficulty. But when you have to process information at higher degrees of understanding, you tend to make less sense of what you are seeing.
For example, even if you have 20/20 vision, you may find that after reading for a while, your mind wanders, and you get sleepy, daydream, or become bored. Maybe you can enter data into a computer, but you find that following logical patterns of thought, retreiving sequenced data consistently, or tracking fast-moving objects for long periods of time causes eye fatigue.
People who fall into this category-having good clarity but some difficulty interpreting what they see—tend to be a little farsighted. It’s as if their eyes are designed for far looking. On the other hand, those who wear glasses and contacts for nearsightedness tend to be good readers and excellent students because their eyes are well adapted for reading.
All three aspects of vision-fitness decrease over time. It’s as if our eyes run out of gas as we age. Even so, vision-fitness, like body fitness, can be improved. Your eye muscles can be exercised. The nerve connection from the brain to your eyes can be stimulated. Blood flow to your eyes can be increased. The vision-fitness exercises in theses articles will teach you to maximize your vision and to increase your overall feeling of well-being.
