Parts of the Eye

partsof-the-eyeIt might be important for you to find a good deal for discount eyeglasses but knowing how your eye works is equally so! The diameter of each eye is approximately one inch. They nestle in the midst of stored fat and the skull, the function of both is to keep the eyes protected. While there are many different parts of your eyes, the chief components are as follows:

  • Cornea
  • Lens
  • Pupil
  • Iris
  • Sclera
  • Retina

When you look at something, the major components of your eye work together to capture its image. Once the image has been captured, it travels the optic nerve to reach your brain’s occipital lobe. There are no stopovers and the upside down image reaches your brain. It is upside down due to the bending of the light entering through your lens. Thus, your brain has to make sense of what you are seeing first before it can turn it in the correct direction.

While you look for prescription glasses online on Marvel Optics, here are some more facts about your eyes and their photoreceptors:

Within your eyes are special regions that sense light when it strikes them. These are known as photoreceptors for obvious reasons. One type of receptors, the rods are linked with black and white images while the cones, the other type, are concerned with colored vision. On sensing light, the receptors create nerve impulses, which is how we are able to decipher what we are seeing.
