Despite improvements in contact lens materials, many contact lens wearers commonly report symptoms such as discomfort by the end of the day. It has been suggested that daily disposable lenses could have benefits over frequent replacement (bi-weekly or monthly) lenses.
The objective of this study is to evaluate and compare the performance of two daily disposable contact lenses in people who habitually use soft contact lenses.
About the study
This study will be conducted over approximately 2 weeks. The study visits are:
- Visit #1 & 2 (normally both visits are combined) – Screening visit to determine eligibility (1.25 hrs) anddispensing of study lenses (0.75 hrs) – 2 hours total
- Visit #3 & 4 – (normally both visits are combined) – 1-week follow-up visit (0.75 hr) and dispensing of study lenses (0.75 hr) – (1.5 hours total)
- Visit #5 – 1-week follow-up visit and study exit. – (1 hour)
Total time commitment – 5.5 hours (time includes 4.5 hours for study visits plus 1 additional hour for at-home tasks)
The visits will include standard clinical procedures that you might encounter when you attend an eye exam.
