ClinConnect Summary

This clinical trial is comparing two types of soft multifocal contact lenses: Proclear® 1 Day Multifocal and Clariti® 1 Day Multifocal 3 Add. The main goal is to see which lens provides better overall satisfaction for people who need help with different types of vision problems, like seeing things up close and far away, often related to aging.

To participate, you need to be at least 18 years old and have been using soft contact lenses for the last three months. You should have specific vision needs, such as a certain level of reading correction and a certain range of eyesight measurements. However, some people may not qualify if they have certain eye or health conditions, like previous eye surgeries or specific eye disorders. If you decide to join, you will be asked to try both types of lenses and share your experiences with comfort and vision quality. This trial is currently recruiting participants, so it could be an excellent opportunity to contribute to research on better vision solutions for everyone!
