*In the LOA 21 3D Pair, only one eyepiece has the LOA (Lederman Optical Array). The other LOA 21 does not have the array and is therefore called "The Neutral".
When used in a Binoviewer, this creates the 3D. So, when viewing the Moon, the eyepiece with array is removed, and a second matched Neutral replaces it.
Now lunar views are two-eyed, but conventional. The 3D interferes with lunar viewing and is not recommended.
