Objective assessment of visual acuity using the SweepVEP
A simple and reliable method for the objective assessment of visual acuity by optimizing the stimulus used in commercially available systems and by improving the methods of evaluation using a nonlinear function, the modified Ricker model. The model does not require the manual exclusion of data points, making it more reliable and robust against outliers, and, in addition, provides a measure for the noise of the recorded results.
