Daily-disposable contact lens wearers (aged 18-40 years) required


University Ethics Committee number: 16217


Contact lens wearers typically differ in how they rate the performance of their contact lenses e.g. comfort and vision. We are conducting a study to investigate whether various performance measures change over the course of 14 hours of lens wear in contact lens wearers who find their lenses comfortable and those who find their lenses uncomfortable.


Up to 150 volunteers are needed for the first phase of the study, which lasts for two weeks. Volunteers must be aged 18-40 years (inclusive) and have worn daily-disposable contact lenses successfully within six months of starting the study.
