For 25 mm Spectacle Lens. Your individual, improved spectacle lens is put in the ahg-monoframe. With the help of a set adapter and a clamp, the ahg-monoframe is mounted centrically in front of the sight disc or the iris disc. Therefore, your sight defect is corrected directly on the iris disc, conse-quently aiming mistakes are avoided to a large extend.
Only spectacle lenses with an outer diameter of 24 mm can be used.
ahg-monoframe does not correspond to the presently valid rules of DSB and ISSF but can be used in many other disciplines.
