Research shows that cat vision is best at night compared to humans, and worst during the day. Cats, like dogs, have membranes that reflect light back into the retina. Meanwhile, the cat’s ability to see is increased when in the dark, creating a sharp visual web. But during the day or where there is a lot of light, the cat’s irises narrow, reducing the amount of light in, avoiding glare, and improving visibility. Membrane and other parts give cats a better detection than humans. The variation in color of the cat’s eye in photographs closely resembles the interaction between the light and the membrane.
Typically cats have a field of view of about 200 °, compared to 180 ° in humans, with the duplicate field (duplicate image of image obtained from two eyes) smaller than a human. Like most predators, their eyes are directed forward for a picture with depth at the expense of market breadth. The market is highly dependent on eye position, but can also depend on eye composition. Instead of the round pupil (optic fovea) which helps people get better focused vision, cat eyes have a visual strip. Cats can clearly distinguish colors, especially at close range, but not quite.
