Med. prof. only: It's been said red UV light in sunrise and sunsets positively affect the eye...?

Question

(This is not for an essay this is just a question): As in it is just below blue and it expands the retina and acts as a color reset for the eye. But my question is what is the exact role of the retina in terms of light? I know rods and cones are like the color adjustment of screens, and that blue UV or regular UV can kill these cells, but you say they never grow back... but how do they grow with us in early age in the first place? and what about the fact of "ipRGCs" being activated regardless of surroundings? Furthermore if distance is just determined though a bending of light then how do you justify the role of the ligaments behind the eye? If it is purely on a cellular level our vision relies then how does the eye not function without that?

It usually takes a group effort to come up with this much nonsense. I assume that you follow some alternate healing system that knows more about the body than modern science does. If you would break down the nonsense of your question into smaller bits, they can be refuted one at a time. I will tell you that there is no such thing as red UV light. The attached link shows the spectrum of light. You will notice that UV is one place and red is another. UV stands for ultra violet. That means that it is farther down the spectrum than violet. Red light has one wave length and UV another.
