Careers for the visually impaired include roles in education, customer service, and journalism. In some fields, blindness is a strength to employers. For example, visually impaired educators know more about the specific skills needed to get by in daily life, while visually impaired food tasters may judge a meal exclusively by how it tastes and smells with no regard to its appearance. Other careers for the blind depend on the actual level of blindness involved. Many people who are legally blind still have some usable vision and can read guides or flowcharts while talking to customers, while others are completely blind and focus on jobs that you can do with no vision.
