Different Levels of Vision

For much of the sighted world, it is often difficult to make them understand that when it comes to being blind or having a vision disability, there are different and distinct levels of vision.  The word "Blind" is often used as a blanket term to describe someone who does not have perfect or 20/20 vision but I'd like to take a few moments to expand on this.


In our world, there are varying degrees of levels of vision and I myself may or may not get it right so I will apologize in advance.  Here is my take on this topic.


Totally blind - unable to see anything.

Light perception - someone who may be able to discern light and shadows.

Low partial - someone who can distinguish light from dark, sees some shadows, and identify colors.

High partial - someone who can distinguish light from dark, shadows, colors, and may be able to read large print using reading and writing aids.

Low functioning - similar to high partial.

High functioning - someone who has enough vision to travel independently, can read and write comfortably with strong lenses, but does not have enough vision to drive a car.


Of course, my definitions may be disputed by others but I hope that I have given you a feel for what it is all about.  You can learn more by visiting any of the following:
