Hi.
I'm new to this forum and wondered if anyone can help with this problem I have understanding how vision works.
In some ray diagrams of the eye it show the rays converging to a point on the retina and on some diagrams it shows them converging before the retina and arriving at the retina inverted.
The second one makes more sense to me as I imagine that to be the inverted image being formed on the retina. (much the same as a lens forming an image on a piece of paper).
However the other diagram appears on many website and textbooks too.. Surely the rays of light are not converged into a single point on the retina? How would the retina and optic nerve make sense of this??
Can anyone help with my mis conceptions?!
Thanks
