Visual impairments mainly occur in the elderly and people with intellectual disabilities. Blindness only occurs with visual acuity <5%. Many visually impaired see out of focus. There may also be a limited field of vision. Visually impaired makes reading, watching television, and using a computer more difficult. Oral communication can also be more difficult, especially when more than two people are present. People who hear poorly and see poorly, spend a lot of energy on the activities of daily life. For the elderly and people with a mental disability, the assistant is extra alert for low vision and adjusts her communication to the visually impaired. She greets the patient with his name and tells who she is. It provides a safe space in which visually impaired people are not at risk or experience unnecessary discomfort. During a treatment, the assistant always tells in advance which action she will perform. In doing so, she clearly states where objects are located.
