Eyes

Work Like a Camera

The eyeball is just like a camera, letting light through a lens and helping to capture images. In fact, human eyes are part of a classification known as “camera-type eyes”. These tiny cameras can distinguish between color and light, and as light hits the eyes, it is then brought into focus.

Our eyes spend every day processing millions of pieces of information at lightning fast speeds, and turn them into the simple images we see almost instantly. Once the photoreceptors have converted light into an electronic signal, they send a signal to the brain’s visual command center and you have vision as a result.

About half of the knowledge and memory in brain is acquired through our eyes, and losing our vision will result in lost opportunities to receive such messages.

Know more about your eyes

The diameter of the eyeball of a normal eye is about 2.5cm. It is similar in shape and size to a ping pong ball. The visible part of the eye is protected by the upper and lower eyelids, but this is just a small portion of the actual eye. The eyeball sits in the eye socket in the skull, where it is surrounded by bone. The eyes are a very important organ that can be broken down into many different parts that each possesses a unique function, enabling us to see the beautiful and colorful world around us.

Retina

This is where the photoreceptors are located. Photoreceptors are cells that are responsible for translating light into vision

Retinal Pigment Epithelium (RPE)

The RPE is a small layer of epithelial cells adjacent to the retina. It absorbs the light energy focused by the lens onto the retina and helps protect the outer retina from light-generated reactive oxygen species

Macula

The oval-shaped area within the retina where light is focused by the lens is called the macula. Central vision will be impaired or lost if the macula is damaged

Ciliary Body
There are two components to this:

Ciliary Muscle – Responsible for bending or stretching the lens to focus light on the retina for visual focus
Ciliary Epithelium – Responsible for the production and drainage of eye fluid. The fluid helps moisturize the lens and maintain normal ocular pressure

A camera can be fixed if it’s not working properly, but that’s not the case of our eyes. Prevention is better than cure – it is advised to protect your vision and maintain good eyesight today!
