Cat's eyes are amazing. Their beauty is legendary, but that's not all that's astonishing about them.
Many people ask questions about what cats can see. Today I thought I'd talk about a few questions that clients ask about feline eyesight (and one they don't but should).
1. Do cats see in color?
Answer: Not really. The ability to detect color comes from nerve cells in the back of the eye called cones. Different nerve cells called rods process the perception of light and dark. Cat eyes contain lots of rods but very few cones, so their ability to determine color is likely very limited. They do, however, have many rods. That sensitivity to light no doubt serves them well as they hunt at night.
2. How do cats see compared to us?
Answer: If you're comparing cat and human vision, cats are definitely the masters when it comes to tracking moving objects. Their ability to discern movement is much better than that of a human. And although humans are much better at distinguishing between objects, cats rule at seeing in low light. They require approximately one-tenth of the light necessary for humans to see (although neither cats nor humans can see in total darkness).
3. Do cats get eye problems?
You bet. Cats can get many eye disease including glaucoma, inflammation in the eye, and corneal ulcers. Eye injuries are common - many of which can be prevented. Most feline injuries occur as cats are playing or fighting, but can also happen accidentally during grooming or scratching. Learn more about corneal ulceration in cats
When cats do suffer from a corneal laceration, their veterinarian will likely use a special green medical dye to determine the depth and severity of the injury. Read more about it, go to: Fluorescein Stain Test
Signs of an eye injury include squinting, rubbing at the eye, or redness in the surrounding tissues. Squinting is usually a sign that something is wrong. Learn about this important symptom here.
