A) As shutter is to camera; eyelid is to eyes.

• The shutter of a camera works to open or close the main lens of the camera,in order to allow or block the light rays which are reaching to the main lens of the camera.

• Now,the work of eyelid is also similar,the eyelid opens or closes in order to allow or block the light rays which are trying to reach our eyes.

B) As film is to camera, retina is to eyes.

• The film of the camera captures the image which is projected upon the film by the incoming light rays from the main lens of the camera.

• The retina also has similar functions,the light rays which are entering in our eyes, projects the images on our retina which later processed into our brain to get the visualisation.
