## What is CatLens?

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

REAL-TIME CAMERA
No pre-recorded effects. CatLens processes your live camera feed in real time using custom WebGL shaders. Switch between animals instantly, toggle between front and back cameras, and watch the filter adapt to changing light conditions.

CAPTURE & SHARE
Take photos through any animal filter and save them to your gallery. Share your cat-vision photos with friends and fellow cat lovers.

730+ CAT FACTS
Discover fascinating facts about feline vision, anatomy, behavior, and history. Learn why cats see better at night, how their pupils change shape, and what the tapetum lucidum does.

WHAT'S NEW IN v1.3.0
- Enhanced Eagle vision with sharper detail rendering
- Improved Snake thermal vision overlay
- Smoother photo capture experience
- Performance optimizations across all filters

### 2/5 — Just black but facts r cool

*2026-05-10*

When I use it I’m able to open it up and everything, but when I switch to what cats see it’s just black, and it also gives me like a pop up that says screen is black. Even though the camera didn’t work the facts were cool and I learned some new things.
