    Been having eye trouble so went into doctor found out I have an astigmatism! I always shoot with contacts but have an insert for my glasses. The doctor said they could add the astigmatism to the lenses but I would only be able to see 100% by looking through the center of the lense? I kinda lost him. Im a one 1 eyed shooter, I have my left eye tapped! My left eye is fine with a normal percription. I have thought about trying to correct my somewhat of a cross eye domminance but what would you do? Try the lenses but keep everything else the same?

    I did. Lasik cured that issue really quick.

    bh11, I have astigmatism and wear prescription shooting glasses. I don't wear contacts. One of the reasons is the number of complaints I hear from shooting buddies who do. Contacts with astigmatic correction introduce a "distortion" into the lens to correct the distortion (astigmatism) of your eye. In essence, the lens of your eye produces a distorted image and the correction cancels that out.

    Contacts can shift in the eye and when they do the the astigmatic correction is no longer oriented properly. So what you get is your original distortion plus the distortion introduced by the astigmatic correction that is no longer oriented properly. A double whammy. Most of the complaints I hear come from pistol shooters, but it affects everything. I don't hear it from non-shooters, so it may be the recoil from the shotgun/rifle/pistol is what causes the contact to shift. Anyway, that's why I wear prescription shooting glasses. As long as you haven't bent the frames out of shape, they hold the lenses in the correct orientation.

    I have it and from there it went to posterior vitreous detachment in both eyes. Takes your shooting average and puts it right into the tank. The eye doctor has made me wait 6 months to see how/if we are going to do anything about it. Have and appointment in a month.

    Can't see targets very well but it hasn't stopped me from buying guns. :>)

    I hope you can still go out and have fun shooting.

    I get my shooting glasses with no astigmatism correction, I just use the distance vision correction of +1.00 and leave the astigmatism correction out. HMB

    I had it plus extremed near sightedness...Lasix cured that for about 5yrs...then it started coming back and it was actually the onset of a disease called keratoconus(look it up) 1 in 5000 people having had Lasix can get it and its horrible ...get a specialist to fit you with a RGP FULL hard contact and you'll thank me later...it will eliminate a lot of frustration trying to find somehing that lets you shoot your best...I'm one who will tell you be leary of Lasix because you could be another one of the 5000 and if your sight is precious you'll think hard and ask lots more questions before letting them nuke your eyeballs
    If you do get Lasix ..I sincerely hope you're among the other 4999

    I have it also, but have a friend that is going through what Calvin wrote about I was thinking about getting lasix but now I am gun shy

    What messes with me when I am shooting my rifles or pistols is without my glasses I can see the sights but the target is blurry with the glasses the sights are blurry and the target is crisp

    Guess I need to find a better eye doctor

    I am the proud owner of a pretty extreme example of astigmatism, a couple of eye doctors have referred me elsewhere because of it.

    With an astigmatism correcting lens, you have to keep the spherical orientation of the corrective lens in the proper relationship to your eye. Hence, the "you have to line your eye up with the center of the lens" instruction. The precision of that alignment depends somewhat on the amount of astigmatism you have. In my extreme case, 2 degrees off in either direction makes things blurry - "your mileage may vary" as it were.

    The contacts I would have to get look like coke bottles, so those are out of the question for me. I do know they make contacts now that are better than they used to be, you might try a pair of those just to see how they work for you.

    I ended up having a pair of glasses made after I took my gun in, worked with my doc with the gun mounted to line the centers up exactly where they needed to be. She ground a custom set of lenses for me I put in an old frame. It works for me...as long as the field is clear I have mounted the gun correctly. Who needs beads?

    Since your head is in a fixed position on the stock, I would try the lenses, it may not be as bad as you think...Now, if you were a baseball player - say a catcher with a promising future and that happened - you'd be screwed.

    Don't ask how I know. :)

    Good Luck,

    -Drew

    The correction optic or prism is small compared to your field of vision in a set of glasses. The optic also tapers based your Rx in the middle of your vision when the lab cuts the lens material. Also there is curvature of the lens/frame basis to narrow the field. The reason for a shooting frame is to bring the optic up higher for shooting a shotgun and the lab will center the correction prisms on your PD(pupil distance) for horizontal placement. You can prove your Rx optic by moving the glasses around on your face. There is only one true sweet spot and the rest of the lens is not exactly the prescription. There is also a vertex variable. The distance from your pupil to the lens. Changing vertex also changes the way image is perceived as it reflects through the lenses. These are the variables of going from contacts to Rx lenses.

    Keep in mind that the 6 or 8 base curvature of the frame/lenses also creates an optical variable shooting in contacts and using plano lenses. Vertex and lens curvature should be considered.

    Be aware that corrective surgery is not prescribed for all forms of astigmatism. I happen to have a form which cannot be corrected by Lasik, or any other procedure. I'm also not a candidate for corrective contacts.

    During the days when contacts were of the hard variety, it was possible to weight the lens, so it would orient itself correctly, and correct your vision. However, that's not an option with the newer types of contacts. I wore hard lenses for several years, but they were really irritating at times, and I got tired of the intense maintenance.

    My only hope for correction, is when my cataracts get to the point of removal. I've been advised by my ophthalmologist, that newer cataract corrective lenses can be had, which will eliminate astigmatism correction with glasses. However, that's a couple of years down the road. Until then, it's glasses.

    Best, Dennis

    I have it too. Got an exam from Doc. Rively a couple years ago and sent the Rx with the correction to Morgan Optical. Last year I had my best year yet with their lenses in my Ranger frames.

    I have terrible, uncorrected eyesight, and astigmatism. 20/400 or worse in both eyes. Have used contacts for 40+ years. Started with hard and went to softs. Cataract surgery, 4 other surgerys, and much laser welding on right eye. Now use Acuvue in left and Air Optics in right with excellent results. Have spent a lot of time with Dr and ( competent) OD to get it right but is worth it. No need for glasses!

    Just get the new corrective lenses, the doc scared you with the whole "you gotta look out of the middle of the lense"! That's the whole idea behind the decot lenses ( and others presumably) and why the sit high on your nose, so when you lean into the gun, you'll look thru the middle! I've worn them for 28 yrs and shoot just fine!
    Without glasses i cannot read anything, road signs and certainly not see a bird !!

    be careful, the contacts with the astigmatisim correction will rotate to line up correctly ,mine would do this every now and then while i was trying to track the target.couple times a hundred,unerving to say the least,i am back to regular lenses without the correction . get a good DR i think i need to change mine the mayo clinic doesnt want to spend their time with my problem. anyone had any luck with hard lenses with dry eyes?

    Bowhunter - it is good that you are recognizing the many factors for improvement in trapshooting.

    I have asigmatism(s) and I am very left eye dominant (which is right brain dominant - since we know that this is a brain issue, not an eye issue).

    I have worn gas permeable contacts for over 30 years, correcting nearsightedness & the astigmatism. I tape my left shooting lens, however this is to prevent peeking and cross firing as I close my left eye.

    Certainly, you have to see the target clearly, and preferably, the target edges to achieve your best results.

    Accuity in seeing the target in focus to 'lock on' is very important, but also influceing this is your gun fit and mount.

    My personal experience is that the (my) astigmatism is not a factor as important as the mount, technique and target lock - the keys to success.

    Some very knowledgeable folks have posted here with data and physiology of the eye and (possible) effects of an asgitmatism and that is valuable information.

    I have found that in my case, other factors rather than my astigmatism are more important in achieving consistant scores and centered/smoked hits. These are gun fit, mount and technique. I am a mid 90s' shooter, one eyed, astigmatism and all.

    The more you know, and trial and error, will help you reach your goals & improve...good luck!
