“…[ 1 2 3 4 5 6 ] They are often diagnosed at the time of the pre-recruitment stage for a job[ 7 ] and they are not aware of their condition until then. [ 5 8 ] In some cases, they are diagnosed in an annual health screening, which makes it even worse than the pre-recruitment stage, as the individual’s livelihood is immediately at stake. Thus, CVD diagnosis can have a negative psychological impact on their mental state[ 9 10 ] and can adversely affect job prospects.…”

Purpose: To highlight the plight of individuals with congenital color vision deficiency (CVD). Methods: This is a retrospective study in which 191 electronic medical records of individuals with the diagnosis of inherited CVD, who visited the eye institute, between January 2010 and January 2021 were included. The inclusion criteria included diagnosis based on the failure in pseudoisochromatic plates (Ishihara / Hardy, Rand and Rittler (HRR) and age range between 18 and 35 years. The patient’s medical history, age, gender, type of defect, and preference for colored contact lenses was noted. Medical records were excluded if the participant had any other ocular pathology apart from congenital CVD. Results: At least 30% (57/191) of the individuals explicitly requested for color vision examination for a job-related purpose. Amongst them, the most common jobs aspired were army (~25%; [14/57]) followed by police (21%; [12/57]). There was only 2.6% (5/191) of individuals in which the type of CVD (protan/deutan) was classified. Only 5.2% of them (10/191) sought an X-Chrome contact lens trial. Conclusion: This study reported the occupational setbacks experienced by individuals with CVD. This study highlights the need to identify CVD at a younger age, thereby avoiding occupational-related setbacks later in life.

“…[ 2 ] The lack of suitability of these tests in occupational provisions has been questioned previously; however, the consequences and alternative recommendations were not discussed. [ 3 ] The results of the lantern test are more variable as compared with other color vision tests and not validated thoroughly. [ 2 ] In addition, the other disadvantages of lantern tests are the lack of availability and services.…”

Purpose: To evaluate the impact of color vision deficiency (CVD) in medical undergraduates by a more clinically applicable test. Methods: Cross-sectional study of 31 students with CVD (Ishihara diagnosed) asked to identify subject-specific signs/tests requiring color identification on a customized medical multispecialty designed color album test (CAT). They were further subjected to Farnsworth D-15 testing. Results: The error score of CVD students (4 ± 3.2) on 39 plates of color album test was highly significant as compared to the error score of color normal (0.3 ± 0.6). The CAT depicted linear correlation with Farnsworth D-15 and emerged as a valid tool of assessment. Ishihara interpretation did not correlate with the clinical impact of CVD. Nature of error suggests that CVD students can anticipate problems in dermatology, pathology, hematology, microbiology, and biochemistry. Conclusion: Color album test is a more clinically relevant test for CVD doctors to identify specialties where they can anticipate difficulties
