眼

Also known as eyes, eyeball, 👀, 👁👁, eyeballs

感知光線並將其轉換成神經訊號的器官

AI overview

An eye is a sensory organ that detects light and converts it into signals that your brain can understand, allowing you to see the world around you. Eyes matter because they're a crucial part of how most animals gather information about their environment and navigate through life.

眼（英語：eye）又称眼睛、目、目睭，是視覺的器官，可以感知光线，轉換為神經中電化學的脈衝。眼球（eyeball）又称眼珠，是复杂性生物眼眶内部，由眼球壁与眼内容物组成近球状的视觉器官。生物中比較复杂的眼睛是一個光學系統，可以收集周遭環境的光線，藉由虹膜調整進入眼睛的強度，利用可調整的晶状体來聚焦，投射到对光敏感的视网膜產生影像，將影像轉換為電的訊號，透過视神经傳遞到大腦的视觉系统及其他部份。眼睛依其辨色能力可以分為十種不同的種類，有96%的動物其眼睛都是複雜的光學系統。其中软体动物、脊索動物及節肢動物的眼睛有成像的功能。微生物的「眼睛」構造最簡單，只偵測環境的光暗，這對於昼夜节律的有關。若是更複雜的眼睛，視網膜上的感光神经节细胞沿著傳送信號到來影響影响生理调节，也送到控制。
