Definitions

Visually Impaired/Blind refers to "clinically measured visual acuity of 20/200 in the better eye with best correction, or visual field of 20 degrees or less.  Functional limitation refers to the consequence of different levels of visual ability for the performance of common activities." (American Federation for the Blind)

Hard of Hearing/Deaf refers to a "disruption in the normal hearing process that may occur in the outer, middle, or inner ear, whereby sound waves are not converted to electrical signals and nerve impulses are not transmitted to the brain to be interpreted."  (National Institute on Deafness and Other Communication Disorders) 

There are basically four degrees of hearing loss:

mild - 26 - 45 decibel loss (serious for children still learning to talk)

moderate - 46 -65 decibel loss (more difficulty hearing speech)

severe - 66 - 85 decibel loss (a lot of difficulty hearing speech; it is at this level we begin using the term "deaf")

profound - over 85 decibel loss (hearing aids may or may not help, cochlear implants are often an option). (www.deafness.about.com)
