Common Eye Defects

Today we watched a video on common defects of the eye and filled in some notes based on it.  Know where light converges on your retina if you are far-sighted and near-sighted and how lenses can fix the problem.  A second video showed how our brain adjusts the upside down image on our retina for us.  At the end of class we went over some of the multiple choice questions on the optics review.
