    The host of this week's question is: Jerry Worsham

    Question (Topic):The other issue and a larger issue for me is getting a proper sight picture at long distances. Using my sights, targets at 25 yards are so small I don’t feel I can consistently keep accurately aligned with the 10 ring. At these large distances my front site is about the width of the target so how do you get tight groups at farther targets? Also with focus if I keep my focus on the front site the target at 25 yards is very blurry and I can’t be sure if I am perfectly aligned. Now I do have bad vision at distances (not horrible but a little blurry) but I still have this problem with my glasses.

    Answer:

    A clear sight picture is important to accurate shooting. Unfortunately as we get older one of the first things we lose is the ability to have a deep focal range, i.e. the ability to focus on two objects separated by some distance. I have read that our eyes start losing this ability when we reach 19. I don’t know, 19 was a long time ago. What I do know is there are several things we can do to help improve our ability to shoot targets at distance with iron sights. I’ll mention the ones that I have used for GSSF shooting that have helped me.

    Distance targets are the hard part, particularly the 25 yard D-1. You basically have a choice, focus on the target or focus on the sights. Focus on the sights, if your sights are clear you can make sure you have them cleanly aligned. If you have vision problems the first step is to decide if you’re near sighted, far sighted, and/or Presbyopic. Anyone in their mid to late forties and later will start having trouble focusing up close, that’s Presbyopia. If you’re near sighted and this starts happening iron sight shooting can get real tough. The solution I found to be best for me was to get glasses with my dominate eye lens set to focus on my front sight blade, my off eye lens set for distance. This is typically referred to as mono-vision. I trimmed 30 seconds off my stock gun times the first time I used glasses set up like this. And that was the first time I had shot with the new glasses. To avoid having to close your non-dominate eye you can apply a short piece of Scotch tape right at the line of the target. This allows you to keep both eyes open without having your weak eye distract your focus when shooting. By keeping the tape horizontally right at your focus line you can still see down when walking between stages. Note: If you’re over 40 don’t wear sunglasses when shooting, the sunglasses cause your pupils to dilate and so reduces your depth of focus, this is not what you want! Smaller pupil openings increase your depth of focus.


    The factory Glock sights are great for what they are designed for, combat and self defense shooting. Unfortunately I find them to be extremely limiting when trying to shoot quickly and accurately, especially at 20 and 25 yards. The best solution is to find a good pair of black iron sights. I prefer the drop-in adjustable Bo-mars. Black sights limit the distractions you have to deal with when getting a fast, accurate sight picture. Additionally by choosing a sight with a thinner front sight blade and/or wider rear notch you make it easier for your eyes to pick up the sight picture and to get back on target, this is especially important on your second shot at each target. Thinner front blades hide less of the target and make it easier to find the center of the target. A less expensive but less efficient method is to improve your stock sights by applying sight black to them, eliminating the white outline and dot. Additionally you can carefully widen the stock rear sight notch with a Xacto knife and give yourself a little more light on each side of the front sight.

    Aiming is the last part of this equation. With a clear front sight picture your target will be slightly out of focus. At 5, 10 and 15 yards you’ll find you can still see the rings in good light, at 20 and 25 you will need to rely on aiming center mass on the target. I aim for where I know the center of the target to be. I know that my aiming point needs to be centered side to side and mid point top to bottom. Even with my glasses focused for the front sight blade I can still see the outline of the D-1 and pick out my aiming point. This is where practice starts paying off. Set up with a D-1 and try sighting first at 5 yards, check your overall sight picture. Now move to 10 and again check your sight picture. Do this all the way out to 25. This way you can establish exactly what your sight picture should be on your targets, especially the 20 and 25-yard targets. Shoot a few rounds and then bring it in and check. Repeat this drill until you’re comfortable with your aiming point and can find it automatically. There is no substitute for practice.

    any thoughts on shooting glasses tints - amber lenses, etc?

    i put on a pair yesterday for the first time and was shocked at the almost 3d effect

    also - thoughts on sunglasses before your turn to shoot (then changing to your shooting glasses?)

    anyone have anything else to add to this discussion of the shooters eyes? or perhaps is there a more in depth discussion of vision coming up as a later tip?

    ..I don't think I've ever seen anyone wear "tinted" shooting glasses at a GSSF match...I don't know why.

    I'm no expert, but..for me,..I try to find time to give my eyes a break before each stage...close and relax them for 5 minutes or so.

    Seems that all the quick focusing wears me out pretty quick, and if I don't take a break, sometimes my eyes take "extra" long to transition, and won't focus as quickly as I would like them to...which in the past, has cost me w/releasing a shot before I saw what I needed to see.

    I believe Pharaoh tried tinted (amber) lenses at Richmond for a time. Too overcast was the call for any tint. Wearing sunglasses between stages isn't a problem if you take them off in a timely manner so your pupils can constrict before going to the line. My current lenses have the self darking type of tint, that will be replaced with the next pair with straight clear lenses. I had already purchased these before the benfits of shooting without tint became apparent to me. Remember what I said, these things worked for me, and I know they have worked for others. You may find that your eyes work well enough for you doing some of these items but not all. A guy like Jay in his 30s faces a different set of challenges than say me, DannyR, Bobby, Philip or Don at PC. Age has a great bearing on what you deal with affecting eyesight. None of this was of any importance to me 7 years ago, now it has a tremendous effect on my shooting.

    I'm nearsighted, wear bifocals, am left eye dominant and right handed. I shoot best with plain glass shooting glasses (Browning), which allow me to see the front sight clearly. After my lousy performance at Richmond last weekend, I tried several alternatives at practice this morning, and still shoot best with plain glass. Being 59 is no fun.;Q

    I do have a special Glaucoma prescription that reduces the size of your pupils, but I did not use it in the low light at Richmond--It takes 6 hours to wear off.

    I have a set of lens-switchable shooting glasses which are invaluable to me. This past weekend I wore the ambers one day for overcast, and the light grey ones and dark grey ones when it was sunnier. I get headaches from a lot of light, so these glasses have really paid off. I wear contacts when I shoot, and when shooting iron sights I found that putting the close-up lens in my dominant eye and the far-off lens in my weak eye really focused me on the front sight.

    Debbie,

    What do you do to shoot your dot gun with your contacts in and your dominant eye set for close up? I'm wearing glasses and changing between guns. That works but if I could go back to contacts I'd love it.

    im with you there


    the last 6 months or so i have been wearing wilson wraparound safety glasses with a smoke tint pretty much anytime im outside..... driving, shooting, mowing the lawn, etc


    my contacts are another source of headaches for me....
    im getting better at putting drops in my eyes thruout the day (dry eye), and i have been putting in a new pair of contacts the morning of a match to make sure that theres no deposits on the lenses

    but having said that..... right now i have a pair of 2 week extended wear contacts in that i probably should have thrown away a couple of weeks ago (lol)





    a couple web sites i have run across

    polarizing and tinted lenses

    different tint colors
