why human beings have inverted retina???

The ‘inverted’ arrangement of the vertebrate retina, in which light has to pass through several inner layers of its neural apparatus before reaching the photoreceptors, has long been the butt of derision by evolutionists who claim that it is inefficient, and therefore evidence against design. This article reviews the reasons for our having the inverted retina and why the opposite arrangement (the verted retina), in which the photoreceptors are innermost and the first layer to receive incident light, would be liable to fail in creatures who have inverted retinas. I suggest that the need for protection of the retina against the injurious effects of light, particularly with the shorter wavelengths, and of the heat generated by focused light necessitates the inverted configuration of the retina in creatures possessing it.

This is because as the image that fall on retina is inverted.So to make the object to see in an erect way , the retina is inverted
