Whale oil beef hooked! A breakthrough, I can see again ...

[Baal]

Can anyone point me towards where to find these shooting glasses with an iris? I've spent hours searching the 'net over the past few days with no luck.

The listing is organized oddly, but shooting glasses with special lenses etc. are in there.

RJW, I assume the image is seen through just one of the holes - your eye selecting the one which lines up best? So it is really an array of single pinholes, rather than an image being assembled through all holes - or am I wrong?

RobD, you are quite correct. That is why they are indeed a very effective "quick fix". But an adjustable iris attachd to proper shooting spectacles is much better. And, of course, much more expensive.

Say it out loud, and it'll sound like something else said with a newfie accent.

Whale oil beef...

Most illuminating - in the spirit of FUBAR, I see.

As to where to find shooting glasses with iris attachments - simply climb out of the milsurp trench for a mo, and take a look at a catalog for serious small-bore shooters - from Anschütz, Gehmann, and the like.

If you have reached advanced teenager status, then you probably know how to shoot well enough, but targets aren't as large and clear as they used to be, while open sights have become figments of the optical imagination.

For rifle shooting, driving glasses are WRONG. Reading glasses are WRONG.
Go to an optician who knows how to set up shooting glasses. Ask around for recommendations. Ask a small-bore competition shooter. The glasses +iris will save their cost in wasted ammo and trips to the range.

Shooting with bad eyesight is like firing a rifle with a bad crown on the muzzle - until you get it corrected, fiddling with any other parameters is a waste of time.

...er, now I would like to know what a newfie is?

...lol, newfie = a person from far east Canada regions, they have a thick rolling accent,

Interesting threads, I'm watching them all, I agree that nothing has put a damper on my shooting so thoroughly as softening focus in my eyesight, for accurizing a rifle I've been getting a friend to do the work, its all a huge pain in the a

I was wondering, what kind of picture does one get with proper glasses? Naturally I tried the reading glasses but of course they focus up one item but leave the other two right out, very fuzzy. In what way is it better with glasses designed for shooters?

"10 SHOOTING AS A GRANDPA
And not as a teenage gold-medalist

So you got your rifle, refurbished it as well as you can, and now you want to get the best results with it? Make no mistake, for us advanced teenagers, we are the limiting factor.

The vision thing

Let us start with the eyes. That also means, most likely, your spectacles. The typical optician has a repertoire of a) glasses for reading or looking at a computer screen b) glasses for driving c) varifocal lenses for those who want it all in one package. Let us take them one by one.

a) Spectacles for reading.
These days they are often optimized for looking at a computer screen. The optimization distance is around 50-60 cm, so that if you look through open sights you will see none of the following clearly: backsight, foresight, target. You may be able to see a spot about halfway down the barrel quite clearly, but that won’t help much. Reading glasses are obviously useless for shooting.

b) Spectacles for driving.
These are typically optimized for about 25 yards or meters, as the authorities insist you must be able to read a number plate at that distance. Personally, I do not normally want to read number plates while driving, considering them to be less of a hazard than the vehicles they are attached to, but I would like to be able to read the dashboard instruments without having to look around the lenses in a peculiar sideways squint. Tough luck, that’s the law! If you use these glasses for shooting, you will be unable to see the ammo to load it into your rifle, and can spend an interesting afternoon watching the butterflies out on the range. You can see the target well enough, it’s just a pity you can’t see the sights at all.

The incompatibility of a) and b) has lead to the development of:

c) Varifocal lenses. If you can get used to these so that you no longer trip over your own feet and do not have to feel your way downstairs, then varifocals are the thing for you - but not for shooting. You can move your head so that you can see target, foresight and (maybe) backsight. But you cannot see all of these at the same time. The slightest movement of your head is going to upset the picture. I know of no-one who shoots successfully with varifocal lenses, but I would be pleased to hear differently.


Why do we have such trouble with spectacles?

The trouble is almost universal with increasing age, and is properly termed presbyopia. As you age, your eyes become less elastic. The ability of the ciliary muscle to shape the lens to focus at a specific distance becomes more and more restricted. The accommodation range of the eye becomes narrower and narrower. The range of accommodation also tends to move further away, as your muscles lose the ability to contract for focusing at short distances, which is why one can end up needing spectacles for driving and another set for reading. As a result, you end up with a pair of “semi-fixed focus” eyes – and it may not be even the same focal length for both eyes. With my left eye I can see revolver or pistol sights with the outstretched arm, but not a rifle backsight. With the right eye I can focus on a spot about halfway down the barrel, but not see pistol sights at all. So I shoot pistols and revolvers left-handed, using the left eye, and, and shoot rifles right-handed, using the right eye. None of the standard optician’s solutions mentioned above can help you solve this problem. And my problem is not at all extraordinary; in fact you could say it is typical for the age.


What to do

The solution (unless you have discovered the secret of rejuvenation) is to have special shooting spectacles made to fit by an optician who is familiar with shooters’ requirements. I traveled halfway across Germany to visit one who is known as the prime address for equipping national team members, but it was well worth the journey (which was arranged to fit in as a diversion on a vacation trip).

It was, literally, an eye-opener to experience the difference in sighting with purpose-made lenses. Believe me, if you are still using your everyday driving or reading spectacles for shooting, then such professionally measured and fitted shooting lenses will put a few points on to your score as soon as you wear them. And the cost is soon amortized by the practice shoots and ammunition you will no longer be wasting in trying to overcome a defective vision setup."

End of quote. If you want any more, get the book!

More later, I need a break!

Thanks Patrick, very interesting, can you tell us what you can see with these new glasses?
I'm not exaggerating to say that this has really quashed my shooting, so a solution is going to be much appreciated. This weekend I get to shoot with the flies eyes glasses I started this thread with, I'll come back with a range report.
By the Way, if anyone here wants a pair of those black plastic glasses I started this thread about I'm happy to buy and ship, if I remember rightly they were $5, and long distance postage like the US or UK, wouldn't exceed $10 because they're very light. Add in maybe $5 for the wrapping etc, so tops all up call it not to exceed $20 US, and I'm happy to refund any small change that comes from the postage etc. paypal is ez to pay with.
