Quality of Life in Presbyopes Using Single-vision Lens and Progressive Lens Correction
Sponsor: The Hong Kong Polytechnic University
Summary
The goal of this clinical trial is to compare the quality of life (QOL) of presbyopes wearing progressive addition lenses (PALs) with that of those wearing single-vision spectacles (SVSs) for near correction. The main questions it aims to answer is: What is the difference in QOL between presbyopes who use SVSs and those who use PALs ? Eligible participants will be randomly assigned in a 1:1 ratio to either the PALs group or the SVSs group.Participants in the progressive lenses intervention group will receive 1-month progressive lens correction in daily life. And participants in single-vision lenses intervention group will use near-vision spectacles during near work and use their original habitual distant glasses for distance tasks for 1 month. The study will compare the QOL scores measured by a 12-item Near Vision-Related Quality of Life questionnaire between the two groups. Additionally, the study will compare the scores measured by the Refractive Status and Vision Profile questionnaire and Visual Analogue Scale questionnaire between the two groups as well as assess the change in the above three questionnaires scores at 1 month following enrollment. And visual acuity of subjects will also be assessed at baseline and at the 1-month follow-up.
