Vision Conditions

Most people eventually experience some kind of vision problem due to the development, growth, or deterioration of the eyes and vision not due to disease. A small percentage of the population are born with common vision conditions like Nearsightedness or Lazy Eye. Vision conditions cause a loss of vision due to a physical abnormality with the eye and the related vision pathways.

In this section you will find more detail about various forms of vision conditions. Count yourself lucky if you see "20/20". However be aware that there is much more to eye and vision health than good vision. Visual acuity (the clarity or sharpness of vision) is measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet.

While the good old eye chart is useful for determining 20/20 vision, it says little about how well the two eyes work together, or the presence or absence of many serious eye diseases that have no affect on visual acuity until severe, permanent damage occurs. This is why a comprehensive eye health and vision examination is necessary.
