See the World Through Cat & Dog Eyes

Upload a photo and see it the way your furry friend would. Simulated from real feline and canine vision science: dichromatic colour, wider field of view, night vision and lower visual acuity.

🐱 How cats see

  • Dichromatic vision: only blue & green cones — red looks grey-green
  • Superb night vision: tapetum lucidum reflects light, ~6× better than humans in the dark
  • Lower acuity: roughly 20/100 — distant details are blurry
  • Slit pupils: vertical pupils control light intake precisely

🐶 How dogs see

  • Dichromatic vision: blue & yellow cones — red and green look alike (like human red-green colour blindness)
  • 240° field of view: eyes on the sides of the head see far wider than humans
  • Lower acuity: roughly 20/50–20/75 — less fine detail
  • Brightness-sensitive: better than humans at distinguishing shades of grey; good night vision
