To analyze age for prescription of presbyopic glasses and factors influencing frequency of their change

Abstract

Purpose: The purpose of this study was to analyze age for prescription of presbyopic glasses and factors influencing the frequency of their change. Materials and Methods: This was a hospital-based cross-sectional study conducted on patients presenting to the outpatient department of ophthalmology of a tertiary care center from January 2022 to June 2022. Informed written consent was taken. History regarding near work was obtained and detailed examination was done. Results: Males 293 (58.6%) had more preponderance than females 207 (41.4%). Occupations such as tailors, teachers, drivers, engineers, and welders required early (<40–49 years) need of presbyopic correction and frequent (2–3 times in the span of 10 years) change of glasses. Individuals with short height, lower upper segment: lower segment (US: LS) ratio, and hypermetropia were in need of early presbyopic correction and frequent change of glasses. Conclusion: Factors contributing to early need of presbyopic correction in age ranging from <40 to 49 years were occupations needing near work, short height, lower US: LS ratio, and hypermetropia. Factors contributing to increased frequency of change of glasses were occupations needing near work, normal to taller height, lower US: LS ratio, hypermetropia, and the usage of visual display units.
