Sensory disability is an impairment of any of the seven senses of a person. It is common among individuals 65-years-of-age and older. Yet, sensory disability is not restricted by age. It is found among those of 5 to 15 years as well as among the older population. Causal factors include birth defects, accidents and the aging process. The most common sensory disabilities are those that affect the senses of sight and hearing. Someone with sensory disability is more apt to be deaf or blind. These impairments must be classified as severe and conform to the statutory criteria if the individual wishes to access the benefits of Social Security Disability Insurance (SSDI). You can find further information under Part A, Section 2 (Adult) and Part B, Section 102 (Children). This may prove to be difficult. For example, someone with a visual sensory disability needs to prove to the SSI that he or she has measurable loss in what is termed the "better eye" and that this affects their ability to engage in "substantial gainful employment." Moreover, the remaining eye does not permit them to function at a specific level for a set period. The criteria are precise and not always related to a specific sensory disability. You may wish to consult an expert in the field to ensure you not only qualify but also are also able to access the correct section of SSDI.
