Filter by:This study will occur in two non-dispensing phases: Phase 1 is a non-randomized, non-masked, non-dispensing study where subjects will wear their own contact lenses for approximately 1 hour. Phase 2 is a controlled, randomized, double-masked, contralateral non-dispensing study where the study lenses will be worn in a daily wear modality for approximately 3 hours.
The proposed protocol is going to study the importance of wide spread of visual functions defined by but not limited to visual perception, visual function, visual exploration, involved in the performance of beach tennis. The investigators intend to examine the basic and important visual function that are required for the better performance in the field. The aim is to assess the efficacy of general training that uses the visual channel as the main one. The investigators suspects the improvement in the visual and motor skills after a predefined 8 weeks of visual training.
This is a bilateral, non-dispensing, randomized, subject masked, four visits, 3-period by 3- treatment crossover study. The objective of this study is to evaluate the effect of JJVC senofilcon A - based contact lens with new UV-blocker on vision and driving performance in both daytime and nighttime lighting under real world driving conditions. This will be achieved through field-based driving studies on a closed-road driving circuit at night and during the day. Quantitative methods will be used to assess vision and driving performance under a range of challenging conditions and appropriate masking, order of testing, randomization and control conditions will be used.
This is a single-masked, randomized, cross-over, dispensing, 6- visit pilot study. The purpose of this clinical study is to evaluate the performance of two marketed multifocal lenses.
The objective of this study is to assess how various silicone hydrogel lenses perform when worn by subjects who are heavy digital device users.
The primary objective of this study is to compare visual degradation in a stressed (forced stare) environment in patients before and after acute administration of Systane Ultra.
