The study was to identify the various binocular vision dysfunctions in different occupations requiring near work. It affects their near work as well as their performance. The cross-sectional study was conducted among 105 participants. Eye examination included visual acuity assessment, objective and subjective refraction, and details of orthoptic evaluation were done. Data was taken in an Excel sheet and analysis was made using the statistical software IBM SPSS Statistics 22.: Of the total (105) participants, 20-20% were equally drawn from each occupation. the mean value of the positive fusional vergence: recovery (near) was noticed low 7.2±3.5 among the teachers compared to 8.5±4.0 among the tailors, 9.4±3.9 among the bankers and higher 11.7±5.4 among the health workers (F = 3.38, p <0.05). The mean of the accommodative facility left eye was high 4.9±2.5 among the health workers compared to 3.6±1.8 among the teachers, 2.7±1.3 among the tailors, and 2.6±1.2 among the bankers (F = 5.11, p < 0.01). Near work for 8 hrs can lead to binocular abnormalities’ despite of occupation. The majority of the groups were affected by accommodative insufficiency and convergence insufficiency. They need to be provided with therapy according to their condition for better symptom relief.
