Five Quick Lessons on the Human Eye from Park Ophthalmology

blue eyeMost people rely on their vision as the primary sense for understanding the world around them. But human eyes are complicated with many components that must work together for the best possible vision. Dr. Beth R. Friedland of Park Ophthalmology in the Triangle area makes it her practice to educate patients about eye health and vision understanding.

Park Ophthalmology offers an outlined summary, in simple terms, of the five major aspects of the human eye and their importance to our vision:

  • Visible parts of the eye: Most people can probably name the pupil, the black circle at the center of the eye that allows light to enter. The iris is the colored portion surrounding the pupil and the white surrounding part is called the sclera. Not visible but important to vision is the cornea, a clear dome that covers the iris and pupil.
  • Lens: The lens is positioned right behind the iris and pupil. The lens serves to focus light entering through the pupil to the back of the eye.
  • Retina: The retina is a delicate membrane that covers the inside of the back of the eye. It translates light waves into electrical signals for the brain to interpret as vision. In the center of the retina is the macula, a small pit that provides the clearest central vision. Cells within the retina are called rods and cones, with rods transmitting black and white images and cones transmitting color images.
  • Optic nerve: The optic nerve is the messenger that sends the electrical impulses from the retina and macula to the brain for processing.
  • Humors: Human eyes also have two kinds of liquid, or humors, that nourish the eyes and give them shape. The aqueous humor fills in the space between the cornea and lens and the vitreous humor fills out the area between the lens and the back of the eye.

Dr. Friedland welcomes all patient questions about their vision and how human eyes work. Do not hesitate to ask questions during an annual vision examination at Park Ophthalmology.
