If you have an android phone, download the Ultimate EMF Detector app. Purchase a pair of reader glasses at your local drug store to use as a control. Go to the woods, far away from any other sources of EMF. Set your real glasses down somewhere safe and walk away 50 feet or so. Put your reader glasses on the ground and use the app to get an EMF reading off of them. Record the value. Get your real glasses and bring them to the same spot you took the reading off the reader glasses. Get a reading of them. Record the value. Repeat at least 20 times. Find the average reading of your readers and the average reading of your actual glasses and see if there is a noticeable difference.
