            Abstract

            Presbyopia, a common age-related visual condition, presents challenges in near-vision correction. This study aims to investigate the impact of presbyopia diagnosis on near-vision correction, particularly focusing on the use of multifocal contact lenses. Additionally, this study compares the visual acuity of subjects wearing spectacles and multifocal contact lenses. A literature review was conducted to understand current practices and challenges in presbyopia management. A clinical study included 20 subjects, who had never worn multifocal contact lenses. Eight out of 20 subjects wear progressive spectacles. The research involved crucial examinations (Interview with subjects, ocular health examination, refraction, fitting), followed by further tests to conduct a thorough study and necessary comparisons of visual acuity. These findings indicated that presbyopes over 55 years of age may have lower near-visual acuity with multifocal contact lenses than with spectacles. Subjective feedback from subjects revealed that multifocal contact lenses were perceived as more comfortable compared to spectacles, with reduced peripheral aberrations. However, a subset of subjects preferred spectacles due to better near-visual acuity. Further research is necessary to enhance near-vision correction strategies for this demographic.
