The Chameleon has very distinctive eyes.
The upper and lower eyelids are joined, with only a pinhole large enough for the pupil to see through.
Each eye can pivot and focus independently, allowing the chameleon to observe two different objects simultaneously.
Each eye has a full 360-degree arc of vision around their bodies. Humans have a 120-degree arc of vision – humans cannot see behind them.
Each eye sees with monocular depth (one depth) and not stereopsis (double or stereo depth like humans).
Its eye sight is very effective, because it can see small insects from a 5-10 metre distance.
It can see both visible and ultra-violet light.
