RESUMO
Color vision deficiency is a condition in which certain colors can not be distinguished, and is most commonly due to an inherited condition. Being color blind does keep one from performing certain jobs and makes other difficult. Compared to persons with normal color vision, they have some trouble differentiating between certain colors, but the severity of the color deficiency is variable. Color blindness is normally diagnosed through clinical testing- Ishihara color test is one of the most common tests used. It is mainly useful for quick screening. From a practical stand point though, many protanomalous and deteranomalous people breeze through life with very little difficulty doing tasks that require normal color vision but in some professions a normal color vision is a necessary requisite. This article focuses on the forensic perspective of abnormal color vision and future research and guidelines for assessing an individual for colour vision.
