Glare occurs entirely internally to the eye, and there are two main types of
glare effects. The first is the corona, which forms the fuzzy glow you see
around a light at night, or the rays which seem to shoot out from the light
of the sun. The second is the lenticular halo, which is only seen when the
pupils are dilated enough and is a color banded halo which is usually
visible surrounding the corona.
Hi Fred,
Yes, this is another reason why using physiological characteristics to
explain otherwise dry, technical issues is so fraught with error.
That error is because not everyone perceives the "problem" (being
"Glare" here) in the same way. Further, within the population of
readers here, cataracts and "Glare" are a very common issue that is
wholly unrelated to the treatment of thin film interference and
"Glare."
I have spent a number of years in designing optical system to reduce
what is called "Glare" in this technical sense. In other words, the
suffering component was an artificial eye, so to speak, a
Photomultiplier Tube (PMT) within a fluorescence detection system that
achieved accuracies in the hundredths of percent. The abysmal math
performed in relation to this topic is amateurish in the extreme,
especially considering that so little more work was needed to offer
vastly better results.
It has been quite obvious that this poor math was necessary to support
a faulty premise: complete cancellation. There is no such thing,
especially within the context of "Glare."
