CatLens - Cat Vision Filter

Ever wondered how your cat sees the world?

CatLens transforms your phone camera into a scientifically accurate animal vision simulator. Point your camera at anything and instantly see it through the eyes of 6 different animals — powered by real vision science and WebGL rendering.

HOW CATS REALLY SEE
Cats are dichromats with only two types of color-sensing cones. They see muted blues and greens, almost no red, and have a wider 200-degree field of view. CatLens recreates this using a 9-step scientific process: light correction, cone simulation, red reduction, night vision boost, blur modeling, barrel distortion, and pupil adaptation.

6 ANIMAL VISION CAMERA FILTERS
- Cat Vision (Free) — Dichromatic color shift, enhanced night vision, slight blur
- Dog Vision — Blue-yellow world with no red-green distinction
- Eagle Vision — Ultra-sharp sight with vivid, saturated colors
- Owl Vision — Near-monochrome with extraordinary night vision
- Shark Vision — Grayscale underwater view through a single green channel
- Snake Vision — Blurry UV-shifted view with thermal heat sensing
