Ok, moving on a bit lets look at something else which is in direct relationship to the already scenario.

A short sighted person needs a lens attached to be able to perceive distance and ''magnify'' the light, how can a lens change the information of a Photon before it enters your eyes to give a better perspective on distance for a short sighted person?

"A short sighted person needs a lens attached to be able to perceive distance "
Nope.
" and ''magnify'' the light,"
Nope.

" how can a lens change the information of a Photon before it enters your eyes "
Because the relevant information it contains is its direction and a lens will change the direction of a photon.
"to give a better perspective on distance for a short sighted person?
"
Still nope.
I can't help thinking it would be better if you started by reading a high school text book and learning about how lenses and eyes work.

By focusing the light photons to impinge exactly on the retina of he eye instead of in front of it as is the case with some people like me who are myopic.

Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus at a point in front of the retina, rather than directly on its surface.
