Yes, you can't eliminate glare within the optics. One of the interesting things
about the human eye is that it has a large amount of internal glare, and
this is counteracted by the large degree of edge sharpening our visual
processing applies. It is also the reason that we model the overall perceptual
response of the eye with a power curve, even though the retina has a logarithmic
response. A good camera with a simple lens actually has less internal
glare than the human eye.
