Over the last 10 years I've had a few weird neurological "episodes" for lack of a better term. As a result I've had lots of diagnostics tests including some non "run of the mill" vision tests for visual field, motion tracking, visual focus etc. They were useless in terms of the neuro stuff but one thing that came out of them was that the eye muscles that control focal length are very weak, and accordingly my ability to shift focal length is, quite literally, retarded. I'm sure this has more to do with sitting in front of a computer for 12-15 hours a day for the last 20 years than any fucked wiring in my brain.
 
Anyway I am curious about the following:
 
Doodies that I'm interested in hearing from know the time for their "flash sight picture" draw that they'd use for a 3-5 yard target. I know mine.
 
Compare that to a draw with a hard, crystal clear, visual focus on the front sight. No target. No "see what you need to see" bullshit. For the purposes of this exercise the "acceptable sight picture" is simply a hard, clear visual focus on the front sight.
 
I'm just interested in the difference. I don't care if your flash sight picture is 0.7 or 1.5.
 
The difference for me is at least 0.5. Typical?

I suspect that as you age the speed at which you change focal distances declines.
Are you now, or have you ever been a member of the Doodie Project?

I struggled with eye issues making it impossible to shoot with front sight focus for years. Solution....shoot something with optics on it.

Response 1: Statement of the obvious
Response 2: Switch to a gay division.
Response 3: Dianobol injections straight to the eye ball.
 
None of you turds have any idea what your numbers are?

The thought never occurred to you to exercise those muscles?

I sit in front of a PC all day like you. Noticed the same changes with regards to changing focal distances.

For the last 3 years or so I've been making a habit of taking breaks to look out the window and focus on objects in the distance. I've place a piece of tape on the window so I can practice moving between near and far objects. Changing focal distances has improved for me.

Yes it did. I do.

 

Your turn: What is the difference in your times?

.5 seems like a very large difference. I'm not sure what mine is exactly, but I'd say it's more like .2-ish or less. From when I first started shooting, I have tried to bring my focus in to where the sights are going to be before they get there, and pick them up visually before the gun is fully extended.

 

If I wait until the gun is up, and then start shifting my focus, it takes longer, especially since I am 55 and suffer somewhat from presbyopia, like all humans eventually do.

I am sure I am on the slower side of that, .6 seems reasonable.

I shoot open, so my difference is .0

With or without Dianobol ?

Hell no. I have no way to measure the speed of my vision. The difference in flash sight picture and hard focus draw times is more dependent on visual acceptance than shifting of focus. FWIW, my eyes and brain aren't even totally connected. When I first glanced at the thread title, I immediately saw the words flesh light and hard.

Before and after if you have them. Trying to decide if I want to go straight to the juice or start off with Bob Vogel's magic eye ball pills.

Honestly, I wish I gave a shit.  It sounds like an interesting conversation.  One that I might be able to gather data on now.

 

I can say, back when I gave a shit (and maybe my eyes were better):

 

1.  I drew to a clear front sight focus.

2.  At 8y in DF, I could go from a front sight foucs while aiming at the lower A-zone, to a transition to the head where my visional focus went to the head and then came back to the front sight...  In live fire, I know that time to be ~ 0.15s.   (well, that was my live fire split time while that vision was going on... no real telling when the focal ques changed)

Yeah that is not even in my frame of reference. 

 

Off-season goal is going to be doing the vision stuff from Seeklander's routinely. And hydrating. And steroids.
