The unveiling of the Google Glass still seems more sci-fi than reality to many. Like any new technological advancement, we should understand the science behind these futuristic specs and their pending impact on our society.
Google Glass is simply a wearable CPU that includes a camera, mic, speakers and a visual lens called a prism. This prism makes use of the electromagnetic spectrum, focusing on visible light. All light travels as waves, and that wavelength defines the various regions of the electromagnetic spectrum. The prism uses a mini projector to transmit light or visuals to your eye’s retina, fovea and optic nerve. This visual layer is projected onto your eye, allowing you to see a digital image layered on top of your actual eye sight.
Some users have complained of eye soreness and a tendency to get headaches coming from their right temple. These symptoms are believed to be related to motion sickness. While there is no evidence of health hazards associated with the use of the Google Glass, some lawmakers are trying to outlaw the use of the glasses while driving, claiming that the additional images being sent to your brain will cause a distraction and can lead to disastrous results.
Naturally, this leads us to more questions than answers. Society will change drastically the more popular and widely used Glass will become. Soon we will need to ask ourselves where do we draw the line between socially acceptable and unacceptable behavior with new technology? What will be the new rules? And more importantly, what will be next?

Begin this lesson by helping your students understand that mirrors reflect light not an image. Many students have a hard time grasping that their eyes actually receive light when looking at an object.
