Typhlology refers to the study of blindness and its effects. Some synonyms that can be used in its place include visually impaired, sightless, and visually handicapped. Others include blind, partially sighted, and low vision. Blindness can be caused by a variety of factors, such as genetics, illness, disease, or injury, which can impact a person's daily living activities. Understanding and educating oneself on typhlology and related terminology can increase awareness and sensitivity towards the blind and visually impaired. Regular eye exams and proper medical care can also help prevent and manage vision loss.
