The crystalline lens is the part of the eye that bends/refracts the light rays as it passes through it.

Light rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape.
The rays of light focus beyond the retina.
The Lens is the part of the eye that bends light rays .
They die.
If light rays do not enter a glass block, they will continue to travel in their original direction. The glass block will have no effect on the path of the light rays unless they actually enter the block.
when light rays enter a new medium in a new angle it may speed up or speed down
It is a ray of light which arrives at a point of reference. The latter may be a point on a mirror, a prism, lens, your eyeball or whatever.

Visible light is part of what is called the electromagnetic spectrum. Light is electromagnetic energy, and so are radio waves, microwaves, X-rays and gamma rays.
