Is there an eye doctor in the house?

Post by JMJ »

Hi, first let me say that I read the articles on shooting glasses at Pilkington as well as an article by Don Nygord, and I'm still unsure of what to do or what I need. I switched to iron sights and feel like I could benefit from shooting glasses, but not sure I can use them given my eyesight. Currently, I have an older pair of glasses that I've had the left lens frosted over, and the right one is a new lens that corrects my eye to 20/20. The problem I have is that depending on how I focus on the front sight, the bull appears slightly blurry to almost not seeable. I can drift my focus that much without much effort to do it. It's pretty frustrating, and I'm not sure what to do.
Here is my prescription:
<img src="http://www.fototime.com/{1D4571DB-7D5B- ... icture.JPG">
My current eye Doc doesn't seem to know much about the shooting sports so I don't want to seek his advice. I'm near sighted, the point where I can see things clearly in front of my face without my glasses is about 8 to 9 inches. after that I can still read some words, but things get blurry. I also have an Astigmatism. What I would like is to be able to have the ideal view of a clear front sight, and a slightly blurred bull without me being able to bring the bull in and out of focus so much without me even trying to do so.
I shoot at distances of 10m, 50ft, 25 and 50 yards. Is there an eye doctor here who might be able to tell me what I can do based on my prescription? I would just hate to buy shooting glasses outright before hearing from a doctor that they will suit my needs. Unfortunately, nobody I shoot with has any type of specialized glasses like varga/champion/knobloch that I could try.
Would an iris solve my problem? Looking for any input.
Thanks

You can use and benefit from shooting glasses.
You buy frame with accessories and you put in whatever power lens you need.
Currently, I have an older pair of glasses that I've had the left lens frosted over, and the right one is a new lens that corrects my eye to 20/20.
Power of the lens should be +.25 to +.50 added to your prescription lens to help you focus relaxed at distance of front sight.
The problem I have is that depending on how I focus on the front sight, the bull appears slightly blurry to almost not seeable. I can drift my focus that much without much effort to do it. It's pretty frustrating, and I'm not sure what to do.
Bull should be blurry. Idea is that you attantion should be on sight aligment and not sight picture (sights and bull aligment). You need to learn to trust your hold and concentrate on sight aligment only. Your brain will adjust that aligment (read the rest of articles on these two web pages).

Since your prescription is not an easy one and I am not a doctor I can not help you here, but if you explain that to your doctor, he shoud be able to help you. Remember you want lens that will halp you to focus relaxed at the distance of front sight, which for normal vision is about 1.5 meter.

You can buy glasses without lens. In fact most places will not carry lanses for you, which you will have to order from your doctor or optition store with doctor prescription only.

It my help , but at the same time it will make trustihg your hold more dificult becouse of bull geting sharper and your focus and attantion shifting to the bull and aligment between sights and bull.

Normal vision focus relaxed at about 1.5 meter. Since front sight is closer, you need to bring that focus closer to whatever that ditance is in your case. Your prescription glasses will bring your focus to normal distance of 1.5 meter, so you need to alter that by adding +.25 to +.5 diopters to your prescription.

So if I understand what you said and what was posted below, I could've gotten my lenses fixed right off the bat and I don't need shooting glasses, correct? If I have bad vision, I can send the frame of the shooting glasses to someone to have proper lenses installed? I was of the opinion that shooting glasses were made for people with 20/20 vision and that you just ordered the .25 or .50 lense that you wanted. I was really hoping for a yellow lense, can most places put the yellow into a prescription lense?
Thanks

Not exactly. Shooting glasses are little more powerful on + side (about +.5 diopter) then your normal glasses (not reading glasses). You can order normal glasses to be like that, but you will not use them for regular use. If you use separate reading glasses, than that +.5 diopter will need to be increse. How much? -depends on how powerful reading glasses are.
I have 20/20 vision and so is my son . He uses +.5 lens but becouse I use reading glasses of +1.5 I found that I had to increse my shooting glasses to +1. diopter.

If I have bad vision, I can send the frame of the shooting glasses to someone to have proper lenses installed?

No. Shooting glasses comes with only one lens holder in perfectly round shape of different diameters. For pistol shooting, larger sizes are recomended, for exemple 42 mm. When you determine
what lens you need you can order round lens in 42 mm and instal yourself( very easy), or take it with you to optition to make shure it fits properly. By the way, they can grind lens to your size while you wait.

Yes, but can be costly.Shooting glasses are worth every penny for flexibility that they provide to shooter. Most places will sell most common lenses and becouse people with bad vision require very wide selection of lenses and need eye egzam they live that to the costumar to handle that with his or her doctor.

My two cents,
I'm not sure if you're a rifle shooter or pistol. If rifle, you might want to investigate using an adjustable rear iris coupled with an adjustment to your current glasses. If you live in the southeast, I've got an eye doctor who loves working with shooters. He's even going to set up a dedicated office for dealing with rifle and pistol shooters. He figures he might also deal with archery shooters.
Anyway, I know folks who are considered legally blind who continue to shoot. They need to see an image, and in fact are able to see the image. They also claim that if their vision is corrected "correctly" and they use a properly adjusted rear iris, they can see both the target and the front sight fairly well.
I have no proof of this, just going off of what my "visually-challenged" friends say.
On the other hand, if you're a pistol shooter, I believe the gentleman who said, "the target should be blurry" is correct. Focus should be on the front sight. Conversely, it ain't so for rifle shooters (maybe that's why we shoot better!! ;( he, he, he). I don't have the best vision either, but I am able to see both the front sight and the target in one plane.
A note of caution: I visited the Optometrist at the Olympic Training Center for a check-up. She swore up and down that I had the incorrect lens for my shooting glasses. She insisted that I should use something very close to my standard correction for regular glasses. OK, she's the boss. She knows more than I do. I had the lens cut, as per her specific directions. I put it in my shooting frame, and.... whamo! Looked like I was shooting through a snowstorm! No kidding. I couldn't see a f-ing thing. The front sight was somewhat OK (but not as good as my normal shooting prescription), but the target was...heck, I couldn't even find the target! Yup, she knew what she was talking about. She must have been anti-gun!
Bring your shooting-stick to the doctors office (with permission). Lay it on a table, so you're able to look through the sights. Point the gun out the window and look at a brick building (or some background with horizontal and vertical pattern). Have the old doc place lenses in front of your eye. If you're a pistol shooter, you may benefit from the use of an adjustable iris, especially for this proceedure. You'll know when you've got the right prescription. You'll be able to see both the target and the front sight.
The methodology here is that the iris (just as with a camera), adjusts the field of view. My understanding is that you adjust the iris until the front sight is dark but clear. Once there, have the doctor, through lenses, bring the target into the same field of view. Works for me, and I ain't the hawk-eye I used to be!

One other comment. I have two pair of shooting glasses, one for pistol and one for rilfe.
The last time I had a lens made, the lab installed the lens in the holder incorrectly. I could not read a large sign across the lobby! It took them two tries before they got the lens installed in the holder correctly.
Also remember for rifle shooters that the lens holder needs to be in the same plane as the rear sight when your head is in position. Otherwise you get the same effect as tilting your glasses.
Good Shooting.

Years ago I got a lens from an eye doctor that had a kit that he sends out to you. The kit has different strength lenses as well as many different tints. You clip the lenses in front of your normal glasses, or just into a frame, and do the work yourself. Then send the kit back and he sends the lens and tint that you asked for.
Maybe somebody here knows who the doctor was. I don't remember. It may have been in the shooting sports paper/mag.

:
This applies to pistol shooters only. You need +.5 diopter
to take strain from eye, because front sight is closer than relaxed eye (1.5 meter). Normal glasses will correct vision to that of normal vision, so that +.5 needs to be added to bring focus closer than 1.5 meter.
If someone uses bifocals (bad regular vision plus age related
short distance- reading glasses) than front sight fall somewhere between regular (distant) and short vision distance. In my case I use reading glasses only, so I don't need correction for normal vision That would indicate that I would need +.5 diopter for pistol shooting glasses, but because my short distance is affected than I need to correct that with additional +diopter, but not as much as reading glasses because front sight is not as close as 16 inches which is distance for reading glasses. So instead of +1.5 I use additional +.5 diopter for total of +1.0. This is approximate , in fact I have couple additional lenses +.75 and
+1.25 to use depends on light condition which affects depth of field and sharpness of sights and blur of bull. I prefer to correct that with lens power first and than with iris so my eye will receive most available light. I hope that this is more clear. I don't know if you had chance to experience reading glasses, but in my case +1.5 is for 16 inches. If I need to work on something small and get very close than I need to use more power like +2.5, on other hand if I watch monitor screen or front sight than I need less power. That's were that only +.5 on the top of +.5 is needed for total of +1.0.
