B585 Posted December 22, 2017 Share Posted December 22, 2017 (edited) With glasses, anytime that you are not looking through the optical center of the lens ( which may not be the actual center of the lens), prism is induced. The farther away from the Optical center you get, the more prism that gets induced. Take your glasses off and hold them about six or 8 inches from your eye and move the glasses left and right. Whatever you’re looking at will appear to move further. That’s the prism being induced. Contact lenses do not cause that. The higher the prescription the more prism that is induced. Yes, you will still have to get used to one eye corrected for distance and one for near, But it is much easier to do with contact lenses that is with glasses. Also, glasses cause there to be a slight change in the size the object Which you don’t get with contact lenses. Most people cannot tolerate monovision with glasses, but many can tolerate it with contact lenses. Edited December 22, 2017 by B585 Link to comment Share on other sites More sharing options...

Most people cannot tolerate monovision with glasses, but many can tolerate it with contact lenses. I see, thanks for clarifying. Appears to be a better alternative to glasses. OTOH, it wouldn't be practical for me though, since I only need the correction when it's my turn to shoot on a stage, while I don't use any correction while not shooting (aside from the brief moments when I'd just have to read something really up close).

B585 Posted December 23, 2017 Share Posted December 23, 2017 Based on your prescription, assuming you are not far sighted and normal height, I would guess you are in your mid-40s which means you can probably wear contacts without too much trouble. This vision problem is only going to get worse as you get older no matter what you do so try to get used to it now while your prescription isn’t very big. Put the contact in first thing when you get up on the day of the match and leave it for the entire match. Your brain will adjust better than trying to put it on (or wearing glasses) right before you shoot. In USPSA, we are doing a lot more than just looking straight ahead or at the front sight. You will be best served if you aren’t changing your vision just before you shoot. Link to comment Share on other sites More sharing options...
sigsauerfan Posted January 12, 2018 Share Posted January 12, 2018 i've posted a thread maybe 4 years ago about this specific topic. my vision is very clear past my front sight,but kind of little blurred inside arm's distance,and i felt the need to address this. went to my eye doctor and he made a contact lens for my dominant eye so i can see my FS very sharp ,while no CL in my ND eye. since i'm still shooting with my ND eye half close , so my dominant takes control, i have a blurred target because my contact lens makes the target at distance blurred....but it doesn't matter at all because we all try to shoot in the center of the target which is where the alpha is. i'm now used to see a blurred target, and just pay attention to the FS and it works pretty good for me .of course i'm getting some charlies lol, but it,s shooter's mistake and not related to a bad vision .

boss281 Posted January 12, 2018 Share Posted January 12, 2018 I just had a special prescription made with my right dominant eye focused on the front sight, and my left eye focused on distance aka the target. I try this out next week. Iron sights have been a problem for about a year as my eyesight deteriorated just enough that accuracy became compromised. I am 60 and only expect this to get worse with time. So far, red dots still work well with my normal nearsighted prescription, and magnifying optics with clear shooting glasses...

I had www.decot.com make me glasses as I use 1.75 readers and front sight is a blur without any correction. 20/20 distance vision. So, they made glasses which are plus 0.75 for my dominant eye (brings front sight in focus sharp) and clear for the other. It has been working great for the last two years.

JeremiahD Posted January 29, 2018 Share Posted January 29, 2018 I'm awfully, awfully nearsighted and use contacts. I'm working through this exact issue on my most recent Rx.. As I dont have anything close to 20/20 in my non-dominant eye, doing a single eye correction is out for me. What I've had to do is work closely with my optometrist to find something agreeable between both eyes. After a long discussion, I found not only does he understand the shooting sports... he belongs to the same club! Last visit, I walked out with multiple sets of lenses to test n the range and throughout the day and report back to him. Long story short, talk to your optometrist, tell him or her specifically what you need and why. you may be surprised with the results. Link to comment Share on other sites More sharing options...
