How many times we just put our Glasses on and go,or start reading,without giving a second thought about what we would do if we had no Glasses.So the question arises,Who invented the first pair of Glasses? And were they unable to see properly? and that prompted the action? anyway, I just paused and offer a Prayer of thanks to GOD for giving some one the wisdom to do it. "Just a thought" have a great day and be thankfull.
