THE EYES FROM THE INSIDE OUT

brought to you by SOLA EyeQ Magazine:

From the outside, our eyes are described by how they look to others - big, or round, or blue, or green. But from the inside, the human eye is a marvel of engineering, capable of out-seeing, out-focusing and out-distancing any man-made camera designed to replicate it's function. To appreciate how our eyes work, and understand what happens when we have problems with our vision, it's important to get to know our eyes from the inside out.

Lens
A transparent, elastic elliptical structure that bends light rays, helping the eye focus for seeing up close and far away.

Iris
The coloured part of the eye, which opens and closes to control entering light.

Pupil
The black opening at the center of the iris, through which light passes.

Cornea
This transparent membrane acts as thw indow to the eyes, bending or refracting light to help the eye focus.

Aqueous Humor
The clear, watery fluid that fills the space between the cornea and the lens, providing nutrition to the surrounding parts.

Vitreous Humor
The clear, jellylike fluid that fills the back portion of the eye.

Retina
The lining at the back of the eye that contains layers of light-sensitive nerve cells called rods and cones.

Optic Nerve
This bundle of nerve fibres carries electrical signals from the retina to the brain.
