Brief Summary
This study is a single-arm, prospective, observational study conducted at one site to evaluate the comfort and vision of the TOTAL30 Multifocal (T30MF) contact lenses over the course of long wear days. The study will assess the proportion of positive subjective Visual Analog Scale (VAS) assessments of comfort and vision at 10, 12, 14, and 16 hours of wear on Days 1, 7, 14, and 30. Additionally, the study will explore subjective assessments of lens comfort using the CLDEQ-8 survey and measure logMAR visual acuity at both distance and near at Visit 1, Visit 2, and after 1 month of lens wear. Participants will undergo three site visits, with at-home surveys conducted at specified intervals to gather real-time data on comfort and vision.
