For example, I want to let my son play outside and told him not to leave my property, say about a 100 yard radius. Does a product exist where I could clip on a transmitter to his belt and it would trigger a base unit to beep if he went outside the 100 yard radius?

Does this happen to anyone else? When I close my left eye and look through my right, the colors seem bright. But when I close my right eye and look through my left, the colors seem dull and dark.
