Procedures For Testing Color Vision

There is a need for comprehensive books that provide crucial information in a clear and direct manner, particularly in the medical field. Currently, there are limited resources available to students and clinicians that provide step-by-step procedures with pictures on how to examine the eye in the pediatric population. The Pediatric Eye Exam Quick Reference Guide: Office and Emergency Room Procedures is a clinical procedure book to provide step-by-step pediatric eye care examination techniques and is an important addition to the field of eye care. The chapters are written by leading pediatric optometrists and ophthalmologists in the field. Years of academic and clinical experiences from schools of optometry, hospital-based eye care, and private practice are all presented in a user-friendly format with clinical pearls and insights that will help any clinician perform a pediatric eye exam easily and efficiently. Covering a range of critical topics such as pupil examination, visual field testing, refraction, and ocular emergencies and providing pictures, it is ideal for all students, residents, academicians, trainers, and novel and seasoned clinicians who are interested in learning how to examine a pediatric patient and staying on top of the latest pediatric eye care procedures.

Color vision tests are used for a wide variety of purposes. Some of these include the rapid screening of congenital red-green defects in industry, transportation, and the military. The classification of discrimination ability within the population of congenital red-green defects is used for job assignment purposes. Another use for screening involves the recognition and diagnosis of congenital disorders for psychophysical or genetic study. In the clinic, screening is used for the recognition and differentiation of congenital and acquired disorders, for the classification of acquired disorders in patients with eye disease, and, in some cases, for the assessment of treatment or for tracking recovery from disease or trauma. Finally, in education and industry, screening for both color vision defects and color aptitudes is used for vocational guidance in occupations or professions that require color judgments. The two major problems faced by those who use color vision tests are (1) to know the color vision requirements of a given task; and (2) to select appropriate color vision tests. (Author).

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.
