Abstract Background: Accommodation is important for maintaining clear vision at different distances and is affected by the refractive status of the eye. Emmetropes usually show efficient and stable accommodation responses. However, changes in how the eye accommodates have been less frequently reported in myopic individuals, with differences seen across various grades of myopia. The above study aims to evaluate and compare the accommodative function in emmetropes and different grades of myopes at a tertiary care centre. Materials and Methods: The cross-sectional study included 100 students who underwent routine eye examination and were later grouped into emmetropes and myopes (mild, moderate, severe) based on their findings. Accommodative tests such as amplitude of accommodation, negative relative accommodation (NRA), positive relative accommodation, AF, and lag of accommodation were performed. The association between the accommodation of emmetropes and myopes was analyzed by the t -test. Results: When moderate myopes were compared to emmetropes, there were significant differences in near point of accommodation (NPA) (right eye OD, left eye OS, and OU), amplitude of accommodation (AA) (OD, OS, and OU), monocular estimated method (MEM) (OD and OS), and NRA ( P < 0.05). A similar comparison between emmetropes and severe myopes also showed significant differences in NPA (OD, OS, and OU), AA (OD, OS, and OU), MEM (OD and OS), NRA, and accommodative facility (OD, OS, and OU) ( P < 0.05). Conclusion: The finding confirms the considerable relationship between relative relaxation accommodation and accommodation facility. Hence, myopes should be aware of their near-related regular tasks to prevent further progression of refractive anomalies.
