PURPOSE: Comparison on vision-related quality of life and acceptance to wear a new kind of photosensitive lenses versus colorless lenses in a group of young people. METHODS: Thirty individuals aged 21 to 35 years with no eye abnormalities and best corrected visual acuity 20/20 in each eye, were separated into two groups for a cross-over study. Phase 1: Consisted of Group 1 wearing clear resin lenses for 30 days and Group 2, photochromic lenses also for 30 days. Phase II: The groups changed lenses. A questionnaire based on Transitions Vision-Related Quality of Life Instrument was submitted before and after the experiment. RESULT: In this study photochromic Next Generation Transitions® lenses provide more comfort and were preferred to clear lenses for outdoor use. CONCLUSIONS: No difficulty was reported concerning the indoor use. For activities such as TV and movie watching a slight preference toward the use of clear lenses was reported.
