What’s in your sight picture?
You might be saying "ouch" at first glance but then you might think again, "what's this all about"? There is no perfect sight picture in reality but most will say :"I 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. But only one, the rifle peep, produces Depth of Field and a sight picture with unprecedented visual acuity unobtainable with the natural eye, even with a prescription. Consider moving the peep to the eyewear lens and now 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. This is also true with the use of plain safety glasses and 20/20 natural vision. 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. See www.EyePalUSA.com for more answers.
