How does one get a visual impairment and blindness certificate?

States may differ: Sounds like you are asking how to be recognized as either visually impaired or blind. The process would involve a medical examination that verifies your loss of visual acuity and function. This is done by an optometrist, ophthalmologist, or primary doctor. The certificate of the disability is then, issued by the state's rehabilitation/disability board. Process for this varies with the state.
