What does Legally Blind mean?

I can’t see past the end of my nose, does that mean I am legally blind?  Not necessarily.  Legal blindness is defined by best corrected visual acuity.  This means what you are able to see through your glasses or contact lens.  If your central vision is measured to be 20/200 or less in your better seeing eye you would be considered legally blind. (Not sure what 20/200 means? Read about it here).  Legal blindness can also be defined by a restricted peripheral visual field.  The normal eye has a visual field that extends 60 degrees nasally, 100 degrees temporally, 60 superiorly, and 75 degrees inferiorly.  If a persons visual field is found to be 20 degrees or less they also would be considered legally blind.
