But most animals have better peripheral vision and can spot something immediately if it moves even slightly to the side. Animals eyes excel over humans in ability to see at night. This specialized layer next to the retina intensifies and reflects lower levels of light, and is present in all animals except birds and monkeys. This layer is what makes animal eyes shine in the dark. Pets experience most of the same eye conditions as humans.
Most dogs are farsighted and astigmatic.
However, since they don t read the newspaper, they seldom complain. Many of the eye problems in pets are inherited. Most breeds tend to have at least one inherited eye problem. Cocker spaniels are subject to cataracts, glaucoma, retinal degenerations and eyelid deformities. When you re shopping for a purebred dog, it is important to know if the breeder screened the animal s parents for inherited eye defects.
