Age takes it toll, then a bit more for luck and the eyes seem particularly affected. Viagra sorts out the other problem but what about the eyes? The bloke I go to for my annual beasting on the range used to be a US team member, is still well respected in the industry and at the arthritic, spectacle wearing age of 64 can still shoot better than most "competitive shooters" half his age. He told me his successful solution to the problem: When you go to an eye surgeon for laser treatment they will offer to zap one eye for close up work and the other for normal/distance work. The brain takes the input and sorts it out into a seamless and viewable image. Applying this solution to shooting is then quite simple - you need to focus on the foresight so you need one eye that can do this and the other to cover all other input. Shooting with both eyes open. Anyway this laser eye treatment theory was taken and applied to shooting specs - talking with people I've found its actually now pretty well used in certain circles in the US as a solution for us myopic types. I took Bill's solution and cobbled together a couple of pairs of disposable specs to try it out. The right lense is 2.5 for close up and the left 1.25. I played with my Heath Robinson construct as was immediately pleased with my ability to focus fully on the foresight with the right eye whilst having a significant awareness of the target and surrounds with the input from the left eye. I have now been to an optician with an explantion of why I want the prescription and my red gun to allow for trialling the prescription during the consult. I told them I why I wanted the prescription and that I was bringing the red gun beforehand as I did'nt want the shopping centre cleared and SWAT in attendance because of a nutter with a gun. Anyway, I took delivery of my speshul prescription shooting specs with the correct magnification and cylinder a week ago. All I can say is if you shoot and the eyes are playing you up go play with the throwaway glasses to prove the point to yourself. I am more than happy with the increased benefit the specs give me and I am looking forward to using them lots. I could probably have gotten away with the throwaway specs but I wanted to be sure of the eye protection so I had some made here: Prescription Safety Glasses | Prescription Safety Eyewear | Bifocal Safety Glasses | Rx Safety I ordered on the friday night and they were with me on the following tuesday, and for you still in service types they do prescription WileyX and I do believe they do international.
