ABSTRACT
Vision is our most precious sense. Our eyes are in constant use every waking minute of every day. The way we use our eyes can determine how well we learn, work and perform throughout our lifetime. Over eighty percent of our learning is mediated through our eyes, indicating the important role our vision plays in our daily activities. The way we use our eyes in our daily routine has changed dramatically over the past number of years. More and more tasks are done at a close viewing distance, and we are working under a variety of workplace conditions. Our visual system must adapt to these changes in order for us to function to our maximum potential.
