eye

An eye is an organ specialized in absorbing light and converting it into electro-chemical impulses that are then processed by the brain. To achieve this, the eye contains photoreceptor cells that contribute to forming a representation of the visual world.

In humans and complex organisms, the iris controls the amount of light entering the eye by adjusting the diameter of the pupil. At night (or in low-light environments), the pupil expands, allowing as much light as possible to enter the eye. Conversely, during the day (or in strongly lit environments), the pupil shrinks, reducing the amount of light that can enter the eye.

As the light passes thought the iris, it goes though a series of lenses that help focus it into an image projected onto the retina, which then encodes that image into neural signals for the visual cortex in the brain. Vision therapy teaches us how to improve eye health through a series of exercises that correct potential focusing problems and improve eye coordination.
