Nearly everyone is born with the potential for good eyes and sight. Vision, however, is learned. And, the way you use and care for your visual system directly affects your enjoyment of play, school or work. Your visual system can undergo tremendous stress these days. Students now read three times the number of textbooks their grandparents did.
Adults constantly use their near vision at work and play.
The shift to computers has engaged a growing number of workers in prolonged, near-vision tasks. The problem is that human beings were not designed to do constant seeing less than arm's length away. We have hunter-soldier eyes for survival, spotting game and enemies at a distance. Only in the last half-century have so many people been forced to deal with sustained, near visual tasks. The result has been a constant stress on the visual system, producing symptoms and eye problems.
