The case for custom EyePal aperture diameters, vision challenges and their applications


Over the past 15 years we’ve received notes, emails and calls about the EyePal aperture diameters and the depth of field they produce. The communications are from those afflicted with illnesses and the resulting effects on their vision.
In one case, despite all the attempts at a lens solution by his eye care specialist, the gentleman still couldn’t see what he needed when aiming his rifle. We met him at the Springfield Gun Show in 2009 and at that time he was 64 years old. He said that he had a distorted cornea since birth.
Using our Benjamin Sheridan air rifle sporting a ghost ring aperture and aiming at a target 10 meters away, he said that both sights and the target were in the blur. With an EyePal Rifle applied on his glasses in his line of sight, he said “WOW – you tricked my eye!  How did you do that?” I said, “I didn’t do it! I just put an aperture in your sightline. The aperture did it.”
He bought the EyePal Rifle kit and that’s the last we saw or heard of him.
There you have it, a shooter with a life-long vision challenge and just a small comment about his reaction to his new sight picture.
But wait – there’s more than meets the eye with another shooter, a veterinarian and a shotgun champion. He call one day last year and started the conversation saying his diabetes changes his vision and is not corrected by his prescription. Would the EyePal help in any way? Having a good number of customers with diabetes, I answered yes. After a few more calls commenting on the larger diameter apertures I made for him, he said the he was now well satisfied with the results of having a larger field of view complete with depth of field and he was now back in championship form for competition.
His experiences with the larger EyePal aperture fostered and produced the EyePal Shotgun kit for the ever-growing number of shotgun hobbyists.
