An experiment with spectacles

Give Merit a try. A suction cup and an iris that can be positioned in front of the eye. They were a standard bullseye item before red dots.
The iris is adjustable, but small opening reduces the circle of confusion (out of focus image on the retina) and sharpens everything up.
 
I did get a merit a year or two ago - it always goes to range. However - being a lazy*** I hardly use it - mostly for more ''bullseye'' stuff - whereas IDPA etc - too much hassle!! It does work well - agreed on that - just has to be afixed each time in right spot.
 
I wear progressives day to day...fine for the red dot but blind on iron pistol sights. Lenscrafters was the only outfit I found locally that offered prescription safety glasses w side shields (lot of indoor shooting where the 22's bounce back).

I used my computer distance script for the dominant eye and plain glass for the off eye...originally used distance and found that the 50' target was a lot worse than just a little blurry...it just smeared in with the background...with the plain glass on the left and a .25 lower than distance on the right, the front sight is sharp, I can see the target and can still use the spotting scope (Bullseye).

I believe they also offered a one year free replacement for scratches which the odd errant case provided within a few range sessions.

UPDATE - not a blistering success!

What I had ideally wanted was not possible - someone mentioned IIRC in a post something like ''not mathematically possible''. Well - they did their best, finding what the computer software would allow.

This meant - forget progressives and go to ''double ''D'' '' - bifocal deal - or in this case of course trifocal. I also had to make a concession on the dioptric power on the top areas - again to suit the computer! This means it is a tad too strong.

Final analysis? Well - they could be used but - take some getting used to, as the upper ''D'' is so large - too large - when I had wanted less intrusion into normal vision area. Couple that with the focal length being too strong - it does not unfortunately get foresight as crisp as I'd like. Not a total waste of time and cash - just not what I hoped for - I was over optimistic. It was worth a try.

They will tho do duty as computer glasses when I need to get within electron range on my monitor!

Here is a pic - excuse the yukky looking frames, they were cheap (like me!). You'll see just how huge those top ''D'' sections are. The lower ''D'' areas do not show well - but they are there - the reading script.

P95-thanks for the follow up. I was the one who mentioned the mathmatical impossibilities, lens design etc. Its a damn shame. Glad to hear that you are not bitter. I just wish that more "opticals" actually knew what they were doing!
The dioptric power can be changed to adjust for your working distance, top seg, bottom seg and middle power! Also, the seperation is variable.
Suggestion..if you are not going to use for shooting sports, why not have them re-made as a wide bifocal/computer pair. The top/ or "distance" portion gets mathmatically adjusted so the dioptric value is set for your computer distance and the bottom bifocal portion is adjusted for your reading power. Very easy to do. Sorry for the rambling. Give me a shout if you need any guidance.

Mr. Tettnanger - Hey - thx for coming back in! Hey, that's not rambling. :)

Well - I still have my separate single script ones for puter - and they are great. Plus - the way these specials worked out, they will have their uses as they are. The lower is good for close work and the upper for close in on puter. Just a bit awkward that the center distance section is so small.

They won't go to waste anyways.
 
Hi P95,
Sorry your double-D's aren't working out for you. I have a question though. When you have the glasses on and are looking straight forward into a mirror, do your irises fall in the middle (non-magnified) portion of the lens, or does the top bifocal cover some of the iris? If it's the later, then they may not have fitted you proper.

My double D's look the exact opposite of yours, with a full bifocal in the lower lens and partial in the upper. Looking straight forward my irises fall right smack in the middle of the two bifocals which allows for normal vision. I have to tuck my chin slightly to use the upper bifocal when shooting.

Rudy Project makes a model called the Exception that has a flip up sunglass feature to be used with prescription inserts. Basically what you end up with is two thick layers of Polycarbonate protection instead of the usual single layer. http://www.rudyprojectusa.com/intros/

I recently purchased a pair and had two sets of prescription Polycarbonate inserts made up. One set has my reading prescription bifocal in the lower portion and the other set with a bifocal in the upper lens that is powered to allow exact distance focus from my eye to the the front sight.

I've found out that for use when shooting, changing out "only" the lens that covers my master eye with the upper bifocal, while leaving the other, lower bifocaled lens in place, allows for a more natural sight picture. The right eye is able to focus on the front sight like it should and the left does what it is supposed to do without the magnification downrange.

TK - well, despite the size of D's - yes, straight ahead does go quite nicely thru the distance area - just that it is not as generous as I'd have liked. So the ''fitting'' was let's say ''OK'' - just that the upper D's would be nice if smaller - this was why I would dearly have liked the impossible! Progressives along a band at the top. :D

Your system sounds pretty good - thanks for the description and link etc - this sounds worth looking into. I think for now I'll press on with what I have - my Nirvana is ellusive! Probably some of my disadvantage can be compensated for by a load more practice and, having CT's means too I have an ''edge'' in lower light. Add to that with the SIG - in real dark, the night sights are very easy to pick out even with my old eyes.

Could be worse.! :)
 
"This meant - forget progressives"

DDrat.

Thanks for looking into it. I'm going to have to figure out what I want to do (and spend.)

Maybe someday folks will be able to get vat grown eyeballs with 20/10 vision implanted while they wait.

Sounds like something out of a science fiction novel, but so does LASIK...
 
MR tett is right

They also make what they call "WEBSPECS" that would cover what you are looking for but distance suffers. they are modified "progressives" that give you the whole "office desk area" view which may help but distance suffers.
MR Tett:
What about measuring "seg height" further up to get into progressive area "earlier"?
May have to tilt head down for distance but the target should be blurry anyway for proper sight alignment and shooting right?...
Or if CL's are an option, even if Lasic is not, how about a monofit CL? should be able to do this even with astigmatism?
 
One of the probs with my script is the degree of axial correction ( a lot - left in particular) - which could I believe even make sclerotic CL's difficult - apart from which I have hyper sensitive corneas and after 40 plus decades of glasses - doubt I'd ever adapt! :)

Had a great shoot today - even with my annoying accomodation impairment!
 
Somebody on another thread (maybe another forum) mentioned these:

http://www.duluthtrading.com/store/list.asp

and I got a full-lens +1.5 diopter safety glasses from them. I usually wear 2.5 to 2.75 for computer and reading. With the 1.5 I can see both rear and front sight on my rifle as well as my pistol - and the target is only slightly blurred.
 
Bubby - those would be good - IF - they had my needed axial correction. Plus of course my hoped-for attempt at getting ''all-in-one'' glasses. Three scripts in one.

Whats the saying ''adapt - and conquer'' LOL :D
 
BeLikeTrey-You could measure the progressive lens falsley high, but that would put your direct line of vision in a "corridor" that is very narrow, and very hard to use unless you are strictly focused straight ahead.

Good thread.
