The lens focuses light rays on the retina - the layer of light-sensing cells lining the back of the eye - to produce a sharp image.
晶状体将光线聚焦于视网膜(排列在眼底的一层光敏细胞)来产生清晰的视觉影像。
The majority of the light rays spend their time refracting off of water droplets and ice inside of the cloud before heading to our eyes.
