Welcome..............there are many thoughts and opinions on night sights, and/or glasses....and those who do not wear corrective lenses, do not really understand what it is like.........I am near sighted w/astigmatism, and a slight bit younger than you, and am also right eye dominant, and color deficient....I have never changed the sights on any of my firearms............I have experimented with different colors(paint) on my sights, including orange, red, chartreuse, yellow, and white............I always go back to white...it seems to be the best color for me......I usually try to let the rear sights go blurry, and concentrate on the front sight....it seems to be the best for my eyes....as far as night sights, I feel that a good light instead, could be a viable option, but then you get the argument that the light sets you up as a target. As far as night sights, I feel that after the first shot, the muzzle flash will temporarily blind you, making any subsequent shots after that a guessing game...which is the reason I have never put nightsights on my firearms. I try instead, to know my house from one end to the other, blind, and also know my wife's nightly habits.....I also have light from streetlights that I can use as a backround, to help identify an intruder. When your eyes aren't normal, you have to do whatever you can, to give yourself the best chance for defending yourself.

Well I have fun. I am left eye dominant & right handed. I shoot about the same L eye Rt hand, or L eye L hand. shooting R eye I have to close my L eye to get site pic, then I can open my L eye & keep the site pic till I shoot. Then have to repeat. I love night sites & am particular to Trijicon. Feel a gun is only half there without them.

berettabone - I am not certain I am utilizing the forum website tools correctly but here goes.

When I shoot in daylight I ensure the front sight is in focus by wearing my "PC glasses". I installed a red pipe in my GP100 .357 front fiber optic sight because I read on the web that red is better (in most cases) for dim light, as in indoor range shooting. I agree completely. I live in the woods, no street lights, and not many neighbor driveway lights. They are finally learning to "carpe nochtem" (seize the night). I only turn lights on when absolutely necessary. My all black cat has paid for that a few times. When there is no moonlight (clouds), it is pitch black. When experimenting with the night sights in the dark with no glasses, I did consider that light would illuminate me, and I feel more than capable of getting around my house in the dark. I never did think about muzzle flash. Thank you for mentioning that point. If I can shoot as well as I think in the dark with the appropriate weapon and ammo, I would hope one shot might be enough to discourage the intruder. Your comment about muzzle flash has lead me to do some research concerning "blinking". I have done some preliminary surfing and have found quite a bit of info on this point. I intend to pursue the issue. If you can condition yourself to not blink and see the muzzle flash when shooting in daylight, you should be able to condition yourself to blink at the exact same time as pulling the trigger and eliminate at least most of the flash. I have already read posts that agree with my point when it comes to blinking automatically at the sound of a round being fired and eliminating some flash. I think that blinking just as you pull the trigger could eliminate most of the flash problem. If you are a decent shooter as far as technique is concerned, I would think that is very possible. Thanks for giving me something else to look into to make my new hobby even more enjoyable.
