  Perhaps your transition glasses have been out of service. Generally, the service time of transtion lens is 1~2 years. If you have worn your transition glasses for a long time, they may not change color anymore because the silver ions embedded in the lenses may have been destroyed. Perhaps you need to change a new pair. See more about transition glasses at http://en.wikipedia.org/wiki/Photochromic_lens

  May be you get a fake one. Go to the place where you bought them and ask for a replacement.

  I've heard that transition glasses are easy to change the color in a low temperature. You can put your transition glasses in the freezer for some time. Then you take them out to see whether they change the color.
