What's in your Sight Picture?

EyePal Chronicle
February 2017

This image may be your sight picture if you're staring at the front sight of a rifle. Instructors tell their students to ignore the blurred back sight and target. The eye will want to wander downrange to the target and back again to the front sight. Ranging back and forth like this causes eyestrain. 
You might be saying "Hey, that's my sight picture" but then you might think again, "so what's this all about"?

There is no perfect sight picture in reality but most shooters and archers will say they have perfect vision when it comes to sighting an iron-sight rifle, handgun or bow. It's a case of coping with what vision is available to you either naturally or by prescription.

But consider the venerable peep-sight. It's generally mounted on the rifle’s receiver or its tang. For the archers, it is mounted in the bow-string. In this case as pictured above, the EyePal Rifle peep, produces Depth of Field and a sight picture with unprecedented visual acuity unobtainable with the natural eye, even with a prescription.  Moving the peep to the eyewear lens, you have what I have come to call an "eye-sight", in as much as the peep is now mounted on the glasses.
The peep is now very small, about 50 thousands of an inch in diameter. But size matters in this instance where the larger the diameter of the peep, close objects start to get fuzzy while distant objects stay in focus. This would be important for handguns and bows as the sights for these are at an arm’s length away from the eye. Distant objects are always clear in both cases where the diameters are suitable for rifles or handguns and bows.

EyePal® sorts out the visual acuity problem straight away. With the application of a small peep (also known as an aperture or pinhole) on any glasses, the resulting image when viewed through the “hole” is remarkably clear. The same is also true with the use of plain safety glasses. If numbers make more sense, the smaller peep produces 20/10 and the larger peep gives 20/15 and both produce Depth of Field, just like the Pinhole Camera. For those familiar with camera apertures and f-stops, the Rifle EyePal is an f40 and the Handgun/Bow is an f30. In the end, the eye sees what it could never see before; an absolutely focused sight picture and truly, a sight for sore eyes. See for more answers.
