Lay the glasses on a piece of white paper and take them back outside on a sunny day, with the front side up. Check to see if the color changes, if they don't change at all then they may have been made with a clear material. Sometimes our eyes don't perceive the change when we look through the glasses because as the lens darkens our pupils dilate.
It is true that a new photochromic lens may act differently for the first couple of cycles when exposed to sunlight.
