 How does the FL-41 filter work? 

Although we are not completely sure why FL-41 improves light sensitivity, it seems to have something to do with the wavelengths/spectrums of light that are filtered out.  FL-41 filters out certain wavelengths of blue and green. These colors are thought to be particularly bothersome to patients with light sensitivity. By blocking these wavelengths of light, this filter also improves contrast and sharpness which increases visual acuity.
