Under the WHO/NIDRR model of disability, impairments and disabilities are 
two different things.  An impairment is caused by pathophysiology, and
describes the inability to contract the muscles of the lens of the eye, to
contract a muscle, and similar types of difficulties.  A "functional
limitation" is the inability to perform an action because of an impairment.
A person who is unable to discriminate text below 14 pt. has a functional
limitation.  A disability is the inability to perform a task in the
environment under consideration.  The inability to read a web page that is
displayed in a small font is a disability.

Note that these are medical terminology, and have specific meanings.  Hence,
the term "visual impairment" is exactly the right term for us to use when
talking about accommodating to a persons abilities so that they have access.
If we do not accommodate, then the person has a disability.
