[ShootingSight]

I just joined. My name is Art Neergaard, I am ShootingSight LLC. I'm torn about declaring myself a commercial interst, because a commercial interest supposes I make money, whilst my ShootingSight venture has been losing money for several years - luckily, I have a day job that pays a salary. I do ShootingSight because I enjoy it.

My background is mechanical engineering with limited work on optics, and an amateur interest in photography. I shoot rifle, mostly Service Rifle, though have had limited forays into Long Range.

What I offer is an understanding of optics that (I believe) will help a shooter attain optimal vision, and I believe I can do it better than most eye doctors. My theories come out of the optics of photography/physics and shooting experience. I am not a doctor, I cannot diagnose or treat eye diseases, but I understand lenses and the needs of a shooter, so those two things let me recommend solutions that work. Eye doctors know the optcal physics and medical issues, but don't understand the needs of shooters. Since most vision issues are not complex medical issues, but are simply presbiopia, little medical understanding is required to help most shooters.

I don't know many European shooters, but count as my friends Mr. Robert Chombart, whom I consider a visionary in rifle design. While he and I might occasionally disagree on a technical matter, the disagreement is really just an excuse to drink Calvados as we further discuss the matter...

Welcome to the forum Art, I am sure you will enjoy it here.

Welcome Art nice to see a colonial freind join the muster. Do you touch the scope side of sights at all?

Welcome to the forum Art, nice to see you here. I know of you products and have always been curious about your rectangular aperture as I suffer from old eyes, my open sight shooting is only with Pre45 action service rifles so additions modifications to the sights are not going to be permitted but it does not stop me wondering how much of an improvement I would see if I used one.

I don't know many European shooters, but count as my friends Mr. Robert Chombart, whom I consider a visionary in rifle design.

A visionary indeed, Robert posts from time to time on this forum and knowing Robert makes for a very good introduction.

Spud,

I have only limited experience with scopes. However I did just have a discussion with someone about making a cylindrical correction lens to put into a scope cover, to compensate for their astigmatism. Project has not moved forward to testing, but I am confident it can work.

Ovenpaa,

Optical math says that for any given focal point, the amount of blur you see is linear with the aperture size. My rectangular apertures are merely a way to get your aperture size about 40% smaller without giving up the light. Hence, the blur you see on the top edge of the sight post, and the bottom edge of the target, will both be about 40% sharper (and the corresponding blur on the vertical edges will be worse). I built a pinhole camera using rectangular apertures to demonstrate the function, and have side by side images taken with rectangular versus round apertures to show the difference. The pictures are posted on my website.

As to your old eyes, you can frequently restore your vision to that of an 18 year old, simply by selecting the right lens.

1. What glasses do you wear to see distance (ie what is the prescription of your everyday glasses)?
2. What glasses do you wear to shoot?
3. What is the distance from your eye to the front sight?

Actually I am off to see the Optician again tomorrow so know better where I am, I wear contacts at -6L and -7R and I know I am closer to -6.75L and -8R so no wonder I cannot see a great deal! The bad news is if I go much higher on my contacts I will not be able to read my wristwatch!

buy a bigger wrist watch then Dave
