Cheetah's eyes| CCTV English

Cheetahs have good eyesight since their eye is elongated, giving them a wide range of vision. The most well-known characteristic is the distinct black "tear lines" that run from the inside corner of the eye down to the corner of the mouth. Cheetahs use these tear lines to block the sun from their eyes, just like a football player who applies black under the eyes to deflect the glaring sun. Cheetahs use tear lines as they roam new territory hunting and running. So, that's the real reason why cheetahs have tear lines. CCTV English is the official channel for CCTV
