In brief: Vision loss
Bindness is a spectrum from loss of all light perception (total blindness), to varying degrees of loss meeting legal standards - vision lower than 20/200 or a visual field less than 10 degrees in extent.
The causes vary - some are reversible, some treatable to prevent worsening, and some permanent. Your ophthalmologist should see you to evaluate your category and treat if possible.

In brief: Legal blindness
In north america legal blindness is defined as visual acuity (vision) of 20/200 or less in the better eye with best correction possible ( big e is 20/400 to give you perspective).
A visual field of less than 20 degrees (the norm being 180 degrees) qualifies for legal blindness as well.
