Figure 1: Contrast sensitivity function for control and multiple sclerosis groups. Mean values with standard deviation bars, differences between means, and best fit curves to mean values. Best fit curve for control means is CSF (ω) = −0.4995 ω3 − 1.036 ω2 + 1.856 w+ 1.706 with R2 = 0.9974. Best fit curve for MS means is CSF (ω) = −0.09305 ω3 − 2.303 ω2 + 2.752 ω + 1.514 with R2 = 0.9985
