If this is about glasses, I think I know what is meant here.
The URL below gives this definition, wich is better, then I could have put it myself:
power rings:
The concentric reflections seen in a concave lens near the edges. Usually more visible in stronger lenses.

Power Ring Settings on Variable Scopes
The power ring on a variable power scope is twisted to increase or decrease the magnification of the target as seen through the scope. The settings are approximations of the power magnification to be had.
This power ring is located directly in front of the rear lens assembly, also known as the ocular lens or exit lens. Closely examine any new scope to determine where this ring is at. Do not confuse the exit lens assembly with this power ring. The exit lens assembly can be screwed in and out but it is not intended for it to be adjusted! Having a ham fisted customer grab the back lens assembly and start twisting it in confusion causes our in house scope expert to holler that he is having the big one and to call an ambulance!
A power setting of 2 (or 2x as it is sometimes called) will approximately increase the perceived size of the target by twice more than the perceived size as seen by the unaided eye. In other words, a target 100 yards away appears to be 50 yards away when seen through a scope set a 2 power. A 10 power setting makes an object 100 yards away look to be only 10 yards from the viewer.
