Adapters and Clips Single Vision Trivex Rx Lenses

The prescription I submitted is exactly the same as what is in my everyday glasses and there is a huge difference. With my everyday glasses road signs are easy to read at a distance. With my new Rx Adapter I have to slide my Rydon sunglasses way down my nose and then they are better, but still not really good. It's almost as if the distance that the eye is from the lens wasn't calculated correctly.
