WebField of view (FOV) is the open observable area a person can see through his or her eyes or via an optical device. In the case of optical devices and sensors , FOV describes the angle through which the devices can pick up electromagnetic radiation . WebAll the light rays coming from one point on the image are focused on one point on the focal plane i.e. the retina. Due to the power of accommodation of the human eye, the lens changes its focal length for objects at different distances to ensure that the image is ALWAYS formed at the focus of the changed lens and thus on the retina.
