Has anyone run across this and is it something that I need to worry about when changing from regular Rx glasses that I've been using for years to bifocals?
Thanks for the help.
To give you an idea of the state of my eyes, I am 73.
I wear tri-focals and have for a number of years.
The top lens is a normal lens for distance.
The center lens, the important lens for shooters, is focused at about 36 inches. This I call my shooting or computer lens. Actually I started using this center lens years ago because I flew helicopters for a living and needed this center lens to see the instruments. It made the front seat passenger nervous if I asked him, "What does that gage read now".
So the center lens is focused at about pistol front sight distance and computer screen, instrument panel distance.
The bottom lens is a normal close up reading lens.
So when I'm shooting I use the center lens to see a sharp front sight. This makes the rear sight slightly blurred and the target more blurred.
Does that sound familiar? It should, that the same thing that's going on with strong eyes.
When you first start using bi/tri-focals it takes a little getting use to, but after a little bit it becomes normal.
Do properly focused tri-focals work OK for shooting? Judge for yourself. The black target at 52 yards is my 2-3 inch barrel S&W J Frame target, and I seldom miss.
Or how about close up shooting with tri-focals?
