Eye Dominance Symposium in Shooting Sports USA

6.5 Creedmoor AnnealingThe digital archives of Shooting Sports USA contain many interesting articles. A couple seasons back, Shooting Sports USA featured a “must-read” expert Symposium on Eye Dominance, as it affects both rifle and pistol shooting. No matter whether you have normal dominance (i.e. your dominant eye is on the same side as your dominant hand), or if you have cross-dominance, you’ll benefit by reading this excellent article. The physiology and science of eye dominance is explained by Dr. Norman Wong, a noted optometrist. In addition, expert advice is provided by champion shooters such as David Tubb, Lones Wigger, Dennis DeMille, Julie Golob, Jessie Harrison, and Phil Hemphill.

Amazing New MicroSight Technology Moves into Production

Microsight Rifle lens Zone PlateIn May, we reported on the new MicroSight invented by engineer (and shooter) David Crandall of the Idaho National Laboratory (INL). The MicroSight keeps both near and far objects in sharp focus, simultaneously imaging two distinct focal planes. This break-through technology allows the shooter to see a sharp image of the target and a sharp image of his iron sights at the same time.

The MicroSight is not a lens per se. Rather it is a phased Zone Plate that focuses light beams through diffraction. Zone Plates, first studied by Frenchman Augustin-Jean Fresnel in the 1800s, focus light via a set of concentric rings that alternate between transparent and opaque. The transparent sections let some light waves pass through unchanged, focusing objects that are far away (basically, at infinity). But light passing the edges of the opaque rings gets diffracted, which brings nearby objects into focus. This produces a seemingly impossible result — sharp images of distant and near objects, simultaneously.

The MicroSight is not just a laboratory experiment. Prototype versions have been crafted and placed on test rifles. INL has licensed the technology to Apollo Optical Systems which is right now working with gunsight manufacturers to adapt the MicroSight design to a variety of products. In the future, some MicroSight-equipped products might add refractive power to the Zone Plate, allowing target magnification as well as focusing.

LaserLyte Offers Laser Integrated into Pistol Rear Sight

An integrated laser sight can be very useful on a defensive handgun. When properly adjusted, the laser displays a small red circle where your shot will impact. When shooting at night, or in a crisis situation where you don’t have time to carefully align font and rear iron sights, a laser sight can be a life-saver. Some people also believe that laser sights can have a deterrent effect — if the bad guy sees the red dot shining on his body, he may withdraw, if you’re lucky.

The problem with most handgun laser installations is that they are bulky or the laser can be obscured by your fingers/hands when holding the gun. Crimson Trace has developed a series of grips with integrated lasers. These work pretty well but we’ve found that you can still obscure the beam with your hands with the smaller pistols. You can mount a laser in front, under the barrel, but then you’ll have trouble finding a holster to fit.

LaserLyte, a small company in Arizona, offers an impressive new system that may be the most practical laser mount yet devised for “carry” pistols used for personal defense. The compact laser and battery are integrated into the rear sight. This mounts the laser up away from the hands. So, you never have to worry about blocking the beam with your fingers, and you can use any “normal” holster.

Introduced in 2009, the LaserLyte Rear Sight Laser (RSL) has proven very popular. It is priced at $199.95, and there are models to fit Glock, Springfield XP, Smith & Wesson M&P, Ruger SR, and other popular handguns. LaserLyte Rear Sight Laser modules come with a one-year limited warranty.
