Comparing Feline And Canine Vision: Do Cats See Better Than Dogs?

When comparing the visual capabilities of dogs and cats, it’s important to understand that each species excels in different aspects of vision. Contrary to popular belief, dogs generally exhibit higher visual acuity and resolution than cats during daylight hours. Ron Ofri, DVM, PhD, DECVO, a professor of veterinary ophthalmology at the Hebrew University of Jerusalem, provides valuable insights into this comparison. Dogs tend to have superior daytime vision, allowing them to see more details and discern objects more clearly in well-lit conditions. On the other hand, cats outshine dogs in nighttime vision, as they possess specialized adaptations that enhance their ability to see in low-light environments. This dichotomy in their visual capabilities highlights the unique evolutionary adaptations that have developed in these two species, enabling them to thrive in different ecological niches.

How does the visual acuity of dogs compare to that of cats? To answer this question, it’s important to understand that visual acuity refers to the sharpness of vision, typically measured using a fraction. In the case of dogs, their visual acuity is approximately 20/75, while in cats, it’s around 20/150. This means that a dog’s vision is sharper than a cat’s, with cats having about half the acuity of dogs. To put it in perspective, if we compare a cat’s visual acuity to that of a horse, a cat’s vision is only about a fifth as sharp. In practical terms, for a cat to see an object as clearly as we do, it needs to be more than seven times closer to the object. This information sheds light on the significant differences in visual acuity between these animals, with dogs having the advantage in terms of sharper vision.
