Bisley 579 Cylinderical Lens System 0-2% Sphere by Gehmann
The device is a combination of optical correction for both axis and astigmatic problems. Axis is set against the rim markings 0 - 180° then locked in place with three allen screws. Sphere is set by use of the two levers which are used in matched but opposing movements for day to day eyesight needs. Depending on levels of eye fatigue, sugar levels etc., your eye sight can change, but with a simple click of the levers, perfect focus can be obtained once again.
Until now shooters suffering from astigmatism have been obliged to use shooter's spectacle frames with their inability to adapt to constant changes in eyesight whether it be day to day or even hour by hour. Subsequently large number of shooters stop shooting as a result due to poor scores and frustration - but not any more.
