Vision includes all the necessary skills that enable us to process the information we receive. Seeing is receiving images while vision is how the brain makes sense of what we see. This tells you that you are reading the bottom line on the chart. The visual deficit may or may not be recognized by eye discomfort or fatigue. Almost everyone is born with the potential for good vision.
Good vision is the ability to identify, interpret, and understand what is seen.
Good vision is developed and learned. Visual performance depends on previously developed visual skills. An infant will learn to smoothly follow a moving target with their eyes before they can accurately change focus from near to far. If one of these important steps is skipped or incomplete in development then visually demanding activities like writing, reading, and reading comprehension, may be difficult and result in frustration and underachievement. Intelligent and motivated people can succeed having a visual deficit, however this results in wasted energy, extra effort, and needless stress.
