People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light  These people do, however, show normal sensitivity to most components of dim light
Their retinal cells are also not excessively sensitive to red components of moderately bright light
Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.
