Eyes have more than 2 million working parts and can process 36,000 bits of information every hour.
Many ancient cultures, from Egyptian to Celtic, used they eye as a metaphor for the sun. Religion looks at the eye as a mirror or window into the soul. At the very least, eyes are a superhighway to the brain, using 65 percent of the pathways to the brain to help us process visual information. But for the brain, they are the most complex organs humans have. Eyes, like many other parts of the body, don’t always work the way they should, and eye problems compound as we age. Ophthalmologists are physicians who specialize in treating eye disorders, Ophthalmology Technology trains students to work with them. Advances in technology and an aging population mean more opportunities in care of the eyes, which continue to inspire philosophers, songwriters and poets. As Henry David Thoreau said, "The eye is the jewel of the body."
