LFR-260 vs Traditional Phoropter in Visual Acuity Testing

An Evaluation of the LFR-260 Against a Traditional Phoropter in Visual Acuity Testing

The purpose of this study is to establish if LFR-260 (investigational device) is not inferior in effectiveness to a traditional phoropter (control device) when applied in visual acuity test in subjects undergoing a full routine eye examination. LFR-260 proposes to provide information of the visual capabilities of the patient. The test will be provided and supervised by a qualified eye care provider. The informed consent, screening, randomization (into the order of visual test device used), (visual) device testing (to include precision testing, remote and offsite testing) will all occur at a single visit.
