Human vision is a combination of “seeing” with the eye and “perceiving” with the brain. The eye has the remarkable ability to convert light into a stream of nervous impulses. Various structures in the eye focuses light on the retina and neurons then take information about this image to the brain for processing and interpretation. Each structure in the eye plays a unique role in assuring that the image you see is the image before you.
This semester 10th grade Institute of Health Science (IHS) students will:
- examine the structure of an eye by completing an eye dissection.
- investigate the many aspects of visual perception by completing station exercises and by interpreting results for tests in visual acuity, depth perception, peripheral vision, color vision, accommodation, optical illusions, and afterimages.
- describe the tests and procedures that go into a routine eye exam, as well as compare three different career paths in the field of vision.
