The human eye is a complex anatomical device that remarkably demonstrates the architectural wonders of the human body like a camera, the eye is able to refract light and produce a focused image that can stimulate neural responses and enable the ability to see. Made of many working parts, the human eye functions much like a digital camera here’s how it works light enters the eye through the cornea , the clear front surface of the eye, which acts like a camera lens.

The human eye's mtf, which is limited at high angular frequencies by the eye's optical system and cone density, does not tell the whole story of the eye's response neuronal interactions such as lateral inhibition limit the eye's response at low angular frequencies, ie, the eye is insensitive to very gradual changes in density.
