Verified step by step guidance

Understand the structure of the eye: The retina is a crucial part of the eye, located at the back of the eyeball. It is responsible for receiving light that the lens has focused, converting it into neural signals, and sending these signals to the brain for visual recognition.

Identify the role of photoreceptor cells: The retina contains photoreceptor cells, specifically rods and cones, which are essential for detecting light and color. This is a key attribute of the retina.

Clarify the function of focusing light: The lens, not the retina, is responsible for focusing light onto the retina. The retina's role is to process the light that has already been focused by the lens.

Determine the layers of the eyeball: The retina is not the outermost layer of the eyeball. The outermost layer is the sclera, which provides protection and form to the eye.

Understand the production of aqueous humor: Aqueous humor is produced by the ciliary body, not the retina. It helps maintain intraocular pressure and provides nutrients to the eye.
