User Satisfaction and Visual Challenges Associated with Progressive Addition Lenses (Pals): A Cross-Sectional Study

Background: Progressive Addition Lenses (PALs) are widely used to correct presbyopia, myopia, and other accommodation disorders, offering a solution for presbyopic patients who require vision correction at multiple distances. However, visual satisfaction and associated complaints among PAL wearers remain a significant focus for improving user experience. Objective: This study aimed to evaluate visual satisfaction and complaints related to PAL use among wearers, with a focus on understanding the impact of different visual tasks and the relationship between usage duration and overall satisfaction. Methods: This cross-sectional study involved 138 participants (response rate: 85.2%) who were surveyed regarding their experience with PALs. Participants were asked to report their satisfaction levels, visual complaints (e.g., eye strain, blurry vision), and the quality of vision across different tasks, including near, intermediate, and distant activities. Data on the duration of PAL use and its correlation with satisfaction were also collected. Statistical analysis, including chi-squared tests, was used to examine associations between visual satisfaction, complaints, and the length of time participants had worn PALs. Results: The results revealed that 50% of participants were satisfied or very satisfied with their PALs. Visual satisfaction was positively correlated with the quality of vision in near and intermediate tasks, such as reading and shopping, while distant tasks, such as driving, showed the lowest satisfaction. Eye strain was the most significant complaint affecting satisfaction, followed by blurry vision. A significant positive association was found between the length of time using PALs and overall satisfaction, with longer usage resulting in better adaptation and comfort. Conclusion: PALs provide effective presbyopia correction, but user satisfaction is influenced by factors such as visual task type, adaptation time, and proper fitting. The study highlights the importance of proper lens fitting, patient education, and adaptation support to improve satisfaction.
