Study Overview
Brief Summary
This study will determine how multifocal contact lens correction affects symptoms of discomfort and asthenopia in a group of myopic contact lens wearers in the non-presbyopic age range (ages 30-40 years).
Detailed Description
The purpose of this study is to determine how multifocal contact lenses affect contact lens comfort in non-presbyopic contact lens wearers. Current soft contact lens wearers who have symptoms of discomfort in their contact lenses will be recruited. Each subject (n = 84) will wear a single vision soft contact lens (Ultra single vision spherical lens) for two weeks and a low add power multifocal (Ultra for Presbyopia) for two weeks. Half of the subjects will wear the single vision lens first, and half of the subjects will wear the multifocal lens first. Initial lens group will be chosen randomly. Subjects will complete surveys that assess their vision and comfort which each lens, and ocular surface and accommodative/binocular vision status will be evaluated at the initial dispense and after wearing each lens for two weeks.

Arms & Interventions
Single Vision First
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.
Intervention: Multifocal Contact Lens (Device)
Single Vision First
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.
Intervention: Single Vision Contact Lens (Device)
Multifocal first
Subjects in this group will receive the multifocal (Bausch + Lomb ULTRA® for Presbyopia) lenses for the first two weeks and be crossed over to the single vision spherical (Bausch + Lomb ULTRA®) lens for the second two weeks. Therefore, this group will receive both study interventions.
Intervention: Multifocal Contact Lens (Device)

Outcomes
Primary Outcomes
Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score
Time Frame: Baseline and after 2 weeks of contact lens wear with each study lens (single vision and multifocal)
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
Secondary Outcomes
No secondary outcomes reported
