A:
Cycles per degree is used to measure how well you can see details of an
object separately without being blurry. It is how many lines you can
distinguish in a degree of a visual field. Humans see 30 cycles per
degree while dogs only see 12 cycles per degree. If a human and a dog
were looking at black and white stripes, the human would see the black
and white more clearly. For the dog, the black and white lines would
blur together more.
