What is the difference between a dispensing and a non-dispensing study?
When a sponsor company requires evidence on the ‘wearability’ of a particular contact lens type or contact lens care product, the product will usually be issued to study subjects for use over a time period ranging from 1 week to 12 months. This is referred to as a dispensing study. Non-dispensing studies involve testing the products only during the study appointment. You do not take any contact lenses or products home with you.
