Lens Reducer Keeps Your Eye Centered for Better Viewing
“Ever had trouble calling your shots? Everything looked and felt great and you swore it was a 10, but it came up as a wide 9? This may be a result of inconsistent eye placement behind the optic. Here’s an affordable solution to help you stay in the 10 Ring.” — Creedmoor Sports
Here is an interesting new product. This scope accessory attaches to the rear (ocular) lens on a scope. It has a center hole in the middle that can help get you on target faster, and get your eye exactly centered in the scope. That will eliminate certain parallax errors.
This scope accessory was invented by White Oak, which calls it a lens reducer assembly. This features a transparent lens with a chamfer around the center hole which acts as a ghost ring, centering your eye in middle of the optic. The transparent lens allows a full field of view so you can still see surrounding targets and target numbers. The lens is held in place by a Butler Creek lens cap.
White Oak’s unique “ghost ring” design allows a full field of view so you can still see surrounding targets and target numbers but acts as a ghost ring centering your eye in the hole, minimizing effects of parallax and helping you call your shots better.
The Lens Reducer Assembly is currently offered by Creedmoor Sports for these three optics PLUS other scopes which use the same Butler Creek Cover listed after each scope:
Konus XTC-30, $34.95, (Butler Creek #18 lens cover)
Weaver K-4, $34.95, (Butler Creek #09A lens cover)
Vortex PST 1-4, $34.95, (Butler Creek #14 lens cover)
To Install: Simply press the lens into the lens cap until it is against the shoulder inside the cap. It will be a snug fit, the snug fit ensures the hole is centered. Then install the lens cap on your scope as usual.
NOTE: Some folks may look at this and be concerned that the grayish chamfered ring will obscure vision. Yes and no. The actual “image” that comes through the scope is a very small-diameter circle of light (“exit pupil”) that will fit fully inside the small, unobscured, fully open circle. So if your head is properly centered there will be NO obstruction. However, if you get out of alignment, then, yes, you’ll see the gray chamfered area, just as you’d see the outside of a ghost ring sight.
