A Study Comparing the Use of Multifocal Contact Lenses to No-Line Bifocal Glasses
Official Title: Evaluation of Quality of Life and Functional Vision with Multifocal Contact Lenses Compared to Progressive Addition Spectacles
This study is looking to compare the use of multifocal contact lenses to progressive-addition (no-line bifocal) glasses. Participants will be asked to perform three different visual tests that measure movement and visual perception, once while wearing glasses, and once while wearing contact lenses. Study visits will conclude with the completion of driving scenarios at the OSU Driving Simulation Laboratory to compare peripheral awareness in these two modalities.
1. Must currently have presbyopia (unable to focus on objects at near).
2. Must have up-to-date pair of progressive-addition glasses (addition power of +1.50 D or higher), worn for at least 2 weeks prior to screening visit.
3. Must be willing to be fitted for multifocal contact lenses, even if already a contact lens wearer.
4. Meet other study eligibility criteria.
