Attitudes are taught. We communicate our judgements of others' abilities in many ways. Attitudes about the limited abilities of blind individuals have been with us for millennia. Remember, if you believe you already have the answers, however bleak they may be, you don't ask questions. The blind diabetic who has been taught by the professionals, word and deed, that he or she is incapable, needs sighted assistance, and faces a shortened lifespan, is not likely to struggle mightily against such pronouncements.
Great accomplishments come from people who believe in their own abilities.
There is every reason to make the achievement of positive attitude an important part of diabetes care. Independence, full participation, and vocational success are achievable.
