Dr. Know investigates the myth that sitting too close to the television screen will ruin your eyesight. He creates a special viewing station to test eyestrain and then offers tips to reduce it. Watch to see what our glued-to-the-screen lifestyle is doing to our eyes.

Dr. Know is real-life physician Paul Trotman. Join him as he debunks, deflates, and demystifies many of the myths we've been told about staying healthy. Topics range from the puzzling and exciting to the titillating and scary, but they're always interesting and filled with facts that will make you say, "I didn't know that."
