Individuals who are blind have no measurable acuity , though they may have some sensitivity to light. Visual Acuity is a standardized scale. No matter what the degree of visual disability, there will be a need to modify standard print materials so that they are accessible to the person with the visual disability. There are multiple methods for doing this.
Braille is used by many blind individuals.
Printed materials can be transcribed into Braille. Notes can be written in Braille. There are many adaptive technical products that read, write, and print in Braille. The Sight Enhancement Center, located in ESS, has a Braille printer for student use. Audio-taped text materials are frequently used by persons with visual disabilities.
