The subject of the poem is life. When you look at it in depth, its entirety is a metaphor for the passing of life. Nature's first green is gold (the birth of a child, or new life), her hardest hue to hold (innocence passes fast with life, no matter how hard we try to hold on to it). Her early leaf's a flower; but only so an hour (again with the quick passing of time for life.) The leaf subsides to leaf. So Eden sank to grief (death at the end of someone's life and the mourning that comes with it, if only a second to the hour of life), so dawn goes down to day (mourning is over, and the days continue after that someone passes and everyone has mourned). Nothing gold can stay (life is valuable, like gold, and vanishes much in the same way).

The human eye is a wonderful instrument, relying on refraction and lenses to form images. There are many similarities between the human eye and a camera, including:
a diaphragm to control the amount of light that gets through to the lens. This is the shutter in a camera, and the pupil, at the center of the iris, in the human eye.
a lens to focus the light and create an image. The image is real and inverted.
a method of sensing the image. In a camera, film is used to record the image; in the eye, the image is focused on the retina, and a system of rods and cones is the front end of an image-processing system that converts the image to electrical impulses and sends the information along the optic nerve to the brain.
The way the eye focuses light is interesting, because most of the refraction that takes place is not done by the lens itself, but by the aqueous humor, a liquid on top of the lens. Light is refracted when it comes into the eye by this liquid, refracted a little more by the lens, and then a bit more by the vitreous humor, the jelly-like substance that fills the space between the lens and the retina.
The lens is critical in forming a sharp image, however; this is one of the most amazing features of the human eye, that it can adjust so quickly when focusing objects at different distances.
