EyePal® Aperture Function with Red/Green-Dots
The EyePal® Peep Sighting System is a glasses-mounted peep similar in design and function to a tang or receiver-mounted aperture sight on a rifle. The aperture is located in the center of an opaque occluder. It has a fixed or adjustable aperture designed specifically for iron-sights and red/green dots. In the EyePal product there are two different fixed aperture diameters that are used for two types of firearms; handguns and rifles. In one instance, the Handgun’s larger fixed diameter will put the pistol’s sights in focus along with the target. Rifle apertures have a receiver-mounted sight and require a smaller aperture to put it focus. Both apertures are set at infinity. They are manufactured of PVC film using dies designed for both Handgun and Rifle aperture diameters. They adhere to clean Rx or plain safety glasses lens by static-cling. The apertures are very durable and are reusable.
Looking through the glasses-mounted EyePal aperture in the line of sight with a handgun will show both sights and the distant target in focus. The only available light is reflected from the target and the sights. As the light rays are parallel, the image has Depth of Field (DOF). The human eye does not have this ability as it has to change focus for each and every distance, i.e., viewing a watch, a computer or a distant road sign
The aperture has a field of view (FOV) determined by its diameter.
An aperture removes the eye's refractive errors. It also provides depth of field (DOF) that the human eye does not have. Sighting a firearm involves viewing three elements at the same time. None are in focus until stared at one at a time. However, the EyePal aperture's image has all three in focus at the same time.
Most quality red or green dot’s LED source will be perfect, too. Just turn down the intensity so that the black bull can be seen easier. All ranges have different ambient lighting so intensity adjustments have to be made for that. Also, before aiming, I suggest closing your eyes for 10-15 seconds to get your pupils dilated. Repeat as necessary.
Having said that, I can assure you that you'll be able to resolve and mitigate most of the eye’s refractive errors with the EyePal Peep Sighting kit. Please ask your Ophthalmologist or Optometrist about his/hers "pinhole occluder" for confirmation of its function and its fundamental relationship with the EyePal aperture sight.
