This week in GEMS, we constructed pinhole cameras to model how the human eye is able to see images. We also made optical illusion spinners to illustrate how our brain can sometimes be "tricked" because it can't work fast enough. What about if you have trouble seeing? How do doctors help people with vision impairments? Anyone who has ever worn glasses or contacts can tell you that life is very difficult when you have trouble seeing. now imagine if you clinically blind. Dr. Sylvia Elfar is a researcher who is working on designing and developing retinal (in the eye) and cortical (in the brain) visual prosthetic devices to help people with severe vision loss regain some of their independence. She is conducting her research at the Ligon Research Center of Vision at Wayne State University in Detroit, MI. She went to college for Experimental Psychology at Berkeley where she learned about how the brain works to allow us to complete every day activities, including interpreting all the things we see.
