text: Glasses are comfortable and LED lights are recessed behind the lenses so the light does not cause reflections. LEDs produce a diffused flood light that is better than spot lights for reading.<br /><br />However, construction and materials fall short. One of the two switches was not attached to the frame, but was hanging by its wires. I glued the switch into the frame and got it working. The left LED a lot is dimmer tan the right. Usable but annoying. And yes, I did install fresh batteries, which did not correct the problem.<br /><br />I will use these glasses until they fail, then spend a little more for something that is constructed properly. I will probably look for lighted glasses in a local store where I can make sure they are well made and work well, and where I can return them easily if they do not work well.
