Brief Summary:
examines the influence of lens-induced defocus on contrast sensitivity-a crucial aspect of visual performance.Each participant experiences both positive and negative defocus through different lenses, with measurements taken for contrast sensitivity using the Pelli-Robson chart. Outcomes are evaluated at baseline, 2 weeks, and 4 weeks to understand the effect of defocus over time.
Detailed Description:
Additional data on symptoms like visual fatigue and computer vision syndrome are gathered using the Visual Fatigue Questionnaire (VFQ) and the Computer Vision Syndrome Questionnaire (CVS-Q), respectively. This study's findings could be instrumental in refining optical treatments, offering insights into how defocus impacts visual function across refractive conditions. Results may ultimately benefit optometric practices by guiding lens prescriptions for improved contrast sensitivity and quality of life for myopic and non-myopic individuals alike.
