Outcome Measures

Primary Outcomes (1)

  • Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score

    After wearing each lens type (single vision and multifocal) for 2 weeks, subjects will complete the CLDEQ-8, a survey that assesses symptoms of contact lens discomfort, to reports their symptoms of discomfort with each lens type. CLDEQ-8 scores with the multifocal will be compared to CLDEQ-8 scores of the single vision lens and the subjects' habitual contact lenses to determine if the multifocal improved comfort. Min-Max CLDEQ-8 range: 0-37 points Higher point values indicate more/worse symptoms

    Baseline and after 2 weeks of contact lens wear with each study lens (single vision and multifocal)

Study Arms (2)

Single Vision First

EXPERIMENTAL

Subjects in this group will receive the single vision spherical (Bausch + Lomb ULTRA®) lens for the first two weeks and be crossed over to the multifocal (Bausch + Lomb ULTRA® for Presbyopia) lens for the second two weeks.Therefore, this group will receive both study interventions.
