Power of the lens, probably the zoom capability of a camera, in a digital camera it can be regarded as pixel the better lens you have the more vivid your images will be.

As this is in the vision category, it's most likely that the OP is asking about the power of the lens in his/her glasses. ;)

Yveted--Are you referring to glasses or camera? These are two very separate questions and therefore cannot be answered in the same thread.

Thanks
