New contact lens study (Study ID: BLUEBERRY)

What are we trying to learn?

The objective of this study is to evaluate the performance of new prototype contact lenses, with particular focus on comfort.  These lenses have been modified in an attempt to enhance the tear film around the lens, with the ultimate goal to improve comfort.

About the study

This study involves 5 study visits across a lens wear period of 2 weeks.  The study visits are:

  • Visit # 1 & 2 (normally both visits are combined) – Screening visit to determine eligibility (1.5 hours)  and dispensing of study lenses (1 hour) – 2.5 hours total
  • Visit # 3 & 4 (normally both visits are combined) – Follow up visit (1 hour) and dispensing of study lenses (1 hour) – 2 hours total
  • Visit 5: End of study visit and study exit  – 1 hour

Total in-visit time commitment – 5.5 hours

You will also be asked to complete 2 short questionnaires during the study (10 minutes in total).

The visits will include standard clinical procedures that you might encounter when you attend an eye exam.
