Abstract

We thank Michael Bach and Steven Dakin and David Crewther and Alexandra Sutherland for their interesting commentaries with regard to the technical issues associated with use of the Freiberg Visual Acuity and Contrast Test (FrACT) (version 1.3) (1) in our study (2). We chose the FrACT for use in our study, because it is both quick and easy to implement and provides us with a quantitative measure of visual acuity (VA) that can be readily interpreted. As outlined in the commentaries, there are a number of settings within the FrACT that can be changed from their default values.
