between cool color tones like purple, blue,
and green, which makes warmer colors like
red, orange, and yellow more attractive.
One of the most common vision-related ailments is cataracts, in which
the lens of the eye “starts to turn cloudy
with a yellowish, brownish tint,” explains
Mark Pennesi, MD, Ph.D., an ophthalmologist at Oregon Health & Science University’s
Casey Eye Institute in Portland. “When the
lens starts to turn yellow, less blue light gets
to the retina.” As a result, the blue-yellow
axis of color vision becomes disturbed.
Pennesi also warns of the effects of
macular degeneration, which can blur
central vision and make objects less bright.
Patients may experience delayed adaptation at changing light levels. Another
common ailment that can affect color
vision is glaucoma. In addition, dementia
can affect vision in a variety of ways, from
perception of patterns to the differentiation of contrasting colors.
