AI-Driven Performance Analytics for Early Injury Prediction in Competitive Athletes: A Multicenter Observational Study

Purpose: Presbyopia leads to a progressive decline in near focusing ability, significantly affecting daily visual tasks and quality of life.Progressive Addition Lenses (PALs) provide a seamless visual transition from distance to near, yet the comparative effectiveness of soft versus hard PAL designs remains clinically debated.This study aimed to evaluate and compare visual performance, user satisfaction, and adaptation patterns between soft and hard design PALs in presbyopic individuals.Methods: A comparative cross-sectional study was conducted among 72 presbyopic participants aged 40-55 years at Hussain Optical Centre, Lahore.A structured questionnaire assessed visual performance across distance, intermediate, and near tasks, along with distortion, comfort, adaptation, and head movement.Responses were recorded using a 5point Likert scale.Statistical analysis was performed to determine associations between lens design and satisfaction outcomes.Results: Overall, 63.9% of participants reported positive performance with PALs.Soft design PAL users demonstrated significantly higher satisfaction (80.8%) compared to hard design users (42.9%).Among first-time PAL wearers, satisfaction reached 90.9%.Soft design PALs exhibited superior adaptability, reduced distortion, and enhanced clarity, particularly for intermediate tasks such as computer work.A statistically significant association was observed between PAL design and user satisfaction (p = 0.001), favouring soft design lenses.Conclusion: Soft design PALs provide better visual performance, comfort, and adaptation compared to hard design PALs in presbyopic individuals.Personalized PAL design selection, aligned with userspecific visual demands, is essential for optimizing presbyopia management and enhancing overall patient satisfaction.
