Shooting Glasses
Shooting glasses are specialized corrective glasses for use in shooting and are used almost exclusively in sport shooting competitions. Like other glasses, they are worn in front of the eyes to compensate for the shooter's ametropia with optical lenses. Functions In contrast to most other eye glasses, shooting glasses usually only have one lens that corrects the ametropia of the dominant eye, which is used for aiming. This lens is selected in such a way that the maximum visual acuity lies on the font sight line element near the muzzle of the (non-magnifying) open type or diopter and globe type match sight line elements to get three points positioned in three different optical planes in acceptably sharp focus at the same time. This is necessary because the shooter can influence the weapon and sight line elements and not the target. It is accepted that the target is not seen with maximal visual acuity when aligning the target with the front and rear sighting elements, especial ...

PPE is needed when there are hazards present. PPE has the serious limitation that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrective Lenses
A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye. Intraocular lenses are surgically implanted most commonly after cataract removal but can be used for purely refractive purposes. Prescription of corrective lenses Corrective lenses are typically prescribed by an ophthalmologist or an optometrist. The prescription consists of all the specifications necessary to make the lens. Prescriptions typically include the power specifications of each lens (for each eye). Strengths are generally prescribed in quarter- diopter steps (0.25 D), because most people cannot generally distinguish between smaller increments (e.g., eighth-diopter steps / 0.125 D). The use of improper corr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Due to the low recoil of air guns and the need for stability, the shooter frequently adopts a deliberately lordotic and scoliotic posture, which allows the non-dominant elbow to be rested against the chest to support the forearm and improves the stability of the shooting stance. The use of specialized rigidly padded vest is allowed to prevent chronic back injury, which can be caused by prolonged asymmetric load on the spinal column. The major competiti ...
