What is average daily vision?
A subjective measurement of how your vision faired during the day. It is easy to get a good idea of the state of your vision by using a set of daily landmarks or signs to judge its current state. You will also find vision varies quite a bit during the day, so you need to take this in consideration when making your evaluation. Many people find that vision is directly related to their current state of alertness and health. As you become tired during a typical day or are ill your vision reflects this.
