Eye Basics

Isn’t it funny how we take things for granted when they work well? When we can see perfectly, we don’t even notice our eyes. But, when something flies into our eye, that’s the only thing we can think about. But, paying attention to something that isn’t working right isn’t a bad thing. In fact, our attention helps us stay safe and protect ourselves so we can heal. Keep reading to learn more about our eyes and how they work.

How We See Things

You likely understand that eyes are complicated. But, did you know that the eye consists of complex structures and that each eye contains its own circulatory system? The process of being able to see all has to do with light. “Seeing” begins when light enters the cornea of the eye and travels through the natural crystalline lens of the eye. The light is then focused on the retina, which is located at the back of the eye.

The macula of the retina is a small, centrally located area which contains a cuplike depression (which is called the fovea). This fovea is packed with cones, which allow us to have discerning, clear vision. Once the images of light are focused on the macula, the optic nerve can move the images to the brain. The brain is then able to translate this information into what we recognize as seeing. This process occurs so fast, over millions of times each day (as we look around and process more information, more must be sent to the brain).

Issues

It is easy to see now how all parts of the eye must be working properly for the eye to function properly and give us the ability to see well. The most common vision problem, refractive error, can often be improved with surgery like LASIK or PRK. Of course, glasses and contact lenses can assist with many vision issues, as well. If you are currently experiencing diminished vision due to cataracts, or you are worried about glaucoma, we can help you understand and treat your various eye issues.
