This function conducts a descriptive analysis of a set of Contrast Sensitivity Functions, either for photopic or mesopic vision with or without glare. The standards of the ISO-11979-7:2018 have been considered for selecting the spatial frequencies for the different conditions [3,6,12,18] cpd in photopic or [1.5,3,6,12] cpd in mesopic vision.1 Normal ranges can be optionally plotted if there is a normal range published in a previous study.2
The Refractive Analysis is an Open Source Toolbox for Matlab developed by Rodríguez-Vallejo M for the Analysis of Vision Science Results. It is freely available for the students of our online course but you need the Matlab software to use it. Matlab software is not provided with the course.
You can enroll in the course by means of the Udemy Platform and follow the course on the same platform or through Udemy App for IOS or Android.
