    I had cataract surgery about 8 years ago and had multi focal lenses installed. I love that I do not need prescription glasses for reading books or my phone, using iron sights on HG and rifles plus no glasses for driving. So if you are in need of cataract surgery consider paying the extra dollars for those lenses. I am just south of 71 and love shooting irons across the board.

    Prior to surgery I found reading glasses to meet my needs.

    i was commenting on the no line bifocals .no matter were you look through them you are looking through a single magnification even if the transition is gradual . the gradual transition may help to find a area that might help. i have switched to optics for.most of my rifles and lasers and optics on my shotguns. got to do what you got to do. i have found that the cheap lasers from china work pretty well and if they mess up you trash them and spend another 20 dollars.

    In what way? They are not used trying to look through both parts of the lens.

    Again I mean no hurt, harm, anguish or turmoil by my post I have posted on this posted subject. I am not baiting, trolling or calling out anyone. I am making a post based on my experience, knowledge and/or belief or opinion. That is all.
    We Know Mass Cannot Be Weighed But It Has Newtonian Weight And That Is Derived From Kilograms And Kilograms Can Be Converted to Pounds. But, Still Mass Cannot Be Weighed. But How is the kilograms obtained? Can Kilograms Be Weighed? Evidentally Yes It Can. But, Still Mass Cannot Be Weighed So Kilograms Must Not Exist. Funny Isn't It.
    One good thing out of this the next time I'm at the doctors and they want to weigh me I'll tell them mass cannot be weighed.

    I’ve been known to wear a pair of reading glasses over my regular glasses at the range, held on by the pressure of my headphones. Looks goofy as heck but I’m 65 and don’t care about that anymore...

    I normally wear glasses with progressive lenses. I only shot rifles nowadays and when using iron sights, my head is turned and I am not looking through the center of the lens.

    I had an optometrist make me a pair a pair of glasses with the center of the prescription in the upper left corner for my right eye. A simple prescription, no progressive. He had me bring in my favorite rifle with iron sights and he calculated accordingly.

    They have helped a lot and didn’t cost much, because they were simple lenses. I didn’t get any extras like anti scratch, however, I may get a new pair this year that darken automatically.

    I'd rather turn the lens on shooting glasses than turn my body/hold/stance to match reading/driving glassing I'm wearing.

    its pretty simple you have 4 points target sights glasses eyes . when lined up it is a single line from eye to target it will go through the glasses in a single spot thus you are looking at a single magnification. you can move the glasses up or down to change the magnification but no matter what you are still looking a single point of magnification when all is lined up unless you have come up with a way to look through more than one point at the same time.

    Please dont take this as being insuborninate because it isnt meant to be, but I would think most people, especially ones that wear glasses, know that one can only look through one part of the lens at a time.
    It would be hard to split ones vision in two and look out two different places on the lens.
    Now there may be some that have read some far out and I mean farrrrr outttttt literature that says it can be done but it cant.

    That is all very true as long as you only use one eye.
    I shoot with both eyes open and am looking through two different lenses when looking at my target and sights. My aiming eye is only able to focus to the distance of the sights. My other eye can focus to the distance of the target. This gives me the ability to see all the distances clearly at the same time.
    A person's brain will "adjust" the image you see when you use both eyes so that you get the sharpest image available to either eye. When I focus on the target, my aiming eye can only see the sights clearly, while my other eye can see the target clearly, all at the same time. The sight to target alignment is just fine.

    Diopter sights really help, but the aperture has to be 1mm or less. Otherwise, they are just peep sights and that’s not the same. The small opening works like a camera lens when the aperture is closed down. It gives you a greater depth of field that helps a lot.

    It's worth while to experiment with inexpensive drugstore readers which are about -0.50 to -0.75 less than your normal reading prescription. That's what worked for me until I got cataract surgery and a new lens in my shooting eye.

    If you are going to be near sighted in one eye and far sighted in the other be advised that it may take awhile to get used to seeing that way. Had my first catarack surgery about 10 years ago. Right eye got very bad. Dr put in a far sighted lens. After 3-6 months I was comfortable reading with my left eye and shooting with my right eye. Eventually the catarack got bad in the left eye and now I am far sighted in both eyes. Can't read the newspaper but I now have the eyees of an eagle after 50+ years of being nearsighted.

    You’re lucky to be eagle eyed now. You don’t really want to read what Is in the newspapers today anyway. Keep on shooting!

    When you are using iron sights the only thing that really matters is being able to focus on the Front Sight. This is NOT something that comes natural as most all of us were trained to shoot with open sight .22's where we shifted our focus from front to rear to target when our young eyes could actually do that.

    My biggest challenge in shooting has been developing the skill of focusing on the front sight. It will be yours as well.

    I wear progressive lenses and when I got my prescription I had the Eye Doc soften the prescription one notch on the closest focus. IE: I wanted a longer short focal length than what the machine showed as the highest amount of correction.

    With this I can focus all the way down to 8-10" but can easily focus on a Front Sight on a rifle that is 3 feet away, by simply shifting my head up or down slightly. After a while wearing Progressive Lenses you will do it unconsciously..

    However there is some technique differences involved to shoot both open and aperture sights effectively.

    Here's what they are.:

    With Open Sights: You will align the front and rear sights first and hold that relationship in place with your cheek weld. On a pistol you hold it in place with your grip and stance. In other words, when you present the gun to the target the first thing that happens is sight alignment, then you simply put the front sight on the target and break the shot. Once the sights are aligned you no longer need to divert attention to the rear sight. I know this sounds simple, but it will take some time to get all of the basics in to where you aren't thinking about them.

    Aperture Sights are easier. With them all you do is look thru the rear sight and put the Front Sight on the target and let fly. Your eye automatically centers the Front Sight in the Rear Sight and if your aperture is sized correctly it will put the front sight in perfect or nearly perfect focus. That aperture will work with either your bare eye or glasses depending. Merit Adjustable Apertures are a great way to figure out exactly what size the Aperture needs to be to properly focus your particular "Optical Solution" to the Front Sight.

    The "Optical Solution" is the complete package of distances from your eye, front sight and target which your brain processes into your "Firing Solution." You don't need to concentrate on all these factors as your brain is doing it for you and all you need to do is put the front sight on the target and pull the trigger.

    With a Pistol as I present from the holster I am making sight alignment as the gun is moving from position #4(extension) to position #5 (ready to fire.) and the only thing left to do is put the front sight where I want and break the shot. I have already taken all the slack out of the trigger as well as most of the creep, and it is ready to break with only a thought impulse when the sight is on target.

    With a Rifle or Shotgun with sights, as you are presenting the weapon you push the gun away from your shoulder and bring it back into the pocket and make cheek weld as the gun seats in the shoulder pocket, as this is being done your eye should be in line with the rear sight Open or Peep, and then the front sight comes into alignment. Then you put the front sight on the target and break the shot.

    After some practice this all comes together and the only thing you concentrate on is the Front Sight and covering the target with it. The key with rifle or shotgun is "cheek weld" as that holds the sights in alignment so you don't have to put any attention on them,,, all you are looking for is the front sight on the target.

    If you are shooting groups or trying to make a precision shot on a target or game animal you need to focus on the target enough to place the front sight correctly. The target will still be fuzzy but still should be good enough to insure proper shot placement. Also since you are shooting off some kind of rest the position of the front sight on the target shouldn't change as you shift focus which should only be a split second anyway.

    I try to have very prominent front sights on my iron sight guns so they are easy to pick up rapidly. Green Fiber Optics are my favorite, with white line front sights being next.

    Get your optics sorted out first then go learn to focus on the front sight.

    Note: You need to go back and read this a few times so you can get all the fine points, there's a lot here to digest and nobody will get it only reading it once thru.

    Then pick up a gun and try it. When have I steered you wrong?

    Burris Fastfire 3's fixed that problem for me, give it a try sometime.

    Tazman you are a lucky man I shoot with one eye closed. Tried keeping both open a lot just can't do it. At pistol range I have given up using sights all together. At 7 to 15 yards I can keep all center mass with or without glasses. I often practice with just safety glasses because I often forget my glasses.

    I always thought of my poor eyesight as a handicap. In this case it may well turn out to be an advantage.
    I will wait a while before I determine which it is for certain.

ID:	233893I turned my rear sights around on my marlin cowboy rifles to move the rear sight farther away from my eye. Makes it a little clearer. My mini or ar’s have red dots or a scope. I went to a hi-viz front sight on my 625 smith revolver that I compete with. I’ve also had shooting glasses made that make the front sight clearer. The red dots work the best. Have a fastfire on my model 41, makes it into a can’t miss pistol. Here’s what my Krag scout rifle scope view looks like.

    Glasses won't fix cataracts. Get your eyes checked. Fuzzy and dim (hard to notice it) - you can 'see' distance but can't 'resolve' the edges? Also often get a 'halo' for bright lites. Peep sights work as they are like a pinhole camera lens.
    At 7 to 15 yards I can keep all center mass with or without glasses.
    Good for SD and you should practice either hand, not both.
    Whatever!
