Title: Bi-focal relief!
Post by: dominic135 on August 28, 2016, 10:20:04 PM
I've spent months on this Forum and some others trying to find out if there is some help for bi-focal shooters!

What I found will be a huge plus for Bi-Foc shooters but will also help shooters with perfect vision. In fact it's one of the very first requirements of the old box cameras from the 19th century... we need a hole!
The old box camera did not have a lens, it had a hole that was uncovered for however many seconds the shot took. When they added a lens later, they encountered another problem. the new lens had to be manually focused for either portrait or landscape.
The good old "hole" some how managed to see both close and distant focus, AT THE SAME TIME!
You don't have to wear glasses to have a problem aiming. Even with perfect vision, the eye will constantly focus near and far and back again. This can distract you from your aim.
Here's what I found! There is a small optic orifice called "The Merit Optic Sight" and can be found on theshootersbox.com for $59.00 plus $10 shipping. It's a small adjustable orifice with no lens. It suction cups to an old pair of shooting glasses, and does everything they claim it does! My first experiment I got pretty intent on what I could do at 10 yds. That may not seem like much to you but beyond 10 yards, I couldn't make out the bulls eye! I didn't try for distance, I was too thankful of 10 yards!
Today I brought it out to 25 yds., as far as our indoor facility can go. I shot better than at any time in my life! At 15, 20, &25yds., my accuracy stayed pretty much the same. At 10 yds. 70% are in the bullseye! 5 & 7yds were just embarrassing to shoot! I felt like a 12 yr old, caught playing with the 3-7 yr toys in front of the cheerleader of my dreams!
Such a little hole in the right place and life can be so cool!

Yeah, works well, but bear in mind you can't use it in competitions.

 I use one of these. It's amazing how well it works! What used to be blurred is much sharper at 15 and 25 yard targets at an indoor range.

Now, if they just made a similar device that worked to steady my hand...  ;D

One of the guys reminded me that I wouldn't be able to use it in competition. Hell! If you're waiting for me to stop shaking, you better be at my funeral!

That a great idea. I've never thought about using this method on the range. I've used this method when I couldn't find my glasses....to find my glasses ::)

This is exactly why rifles fitted with a peep-sight are so accurate

Just to follow up.
I get excited when I learn something knew. I was very surprised the Optic Sight worked as well as it did!
There were a few to remind us what is allowed in competition and also their own experiences in shooting with vision impediments! Thanks all of you!
Today I was going through classicfirearms.com and found myself staring at the rear sights of the M1, as well as the M4, M14 and M1A. They were what is called "Circle Sights". So. even back then gun makers understood the physics of light transmissions. The rear sight is a disc with an optic hole the shooter looks through to find the front sight and target equally focused!
And yet, most readers probably thought, "just another gimmick"! Like the AMA looks at home remedies!!!
I guess the neatest thing is that this company makes a lot of money from technology is so old... it's been forgotten! Good on them!!!

I just noticed that this week. Looking a M1's etc, I noticed the ring sight! Sometimes you just can't top home remedies and long forgotten wisdom!

Note the Peep Sights on the old Sharps
They were the "long Range (1000 yrds+) Shooters" of their day:

Regarding Bi-focal relief, here is my in-solicited slant.  I wear trifocal clear lens--can read and type without them.  I used mid-range for what I call computer screen range which also covers or handles pistol open sights.  I use single vision (long range) glasses for shotgun targets; however, I get get to my comment about pistol use.  First however, I use the distance RX script also for Red Dot sights.  For open sights, my "vision" doctor (an OD) also gives me a script for that he calls "intermediate" (distance for others to understand).  I have lenses ground with that correction.  I get help from Sam Cherry at company DECOT--maybe Internet found site that may be called sometime like sportsglasses.  Bud Decot passed but I but Sam has helped me for years.  For pistol, I tried the top part of lens ground that reminded me of an upside down bi-focal strength.  WELL, I now get my intermediate script strength for the entire lens but I get it in both side (right and left) to be used with open sights.  I can hold up right or left thumb and look at the thumbnail and I can see the ridges on the nail AND I can see sights.  I personally want the open sights to clearly be seen (good to see front and rear sights lined up I guess) but the target sharpness or focus is secondary to me.  Sam works in Arizona and he actually answered the phone last Friday but he will be in sunny San Antonio, TX for the sporting clay's national event next week.  I get the fairly large lens for shotgun shooting.  A plus even for pistol target shooting is that the eye is somewhat in the middle of the lens (not with eye at the top of the lens (if that makes sense)).  I get my pupil distance (also known as PD) measured for each eye.  I do not purchase wrap around lens design.  Some bounce back lead from very close steel steel target shooting might sneak in.  I am not trying to "sell" our CZ forum users any products.
IF any of you recognize Jerry Miclek (spelling?) from TV, he wears glasses that the design that I referenced looks like that.  Some S&W model 625's have stocks with "JM" on them.  That is named after the dude!  I have seen him and his family in person.  Young "Jimmy" Clark passed away.  His sister is Jerry's wife.  The whole family can shoot pistol and shotguns.

I thought all progressive lens's had 3 viewing distances. Reading, Far and Intermediate. Intermediate is usually 2-3 feet like the gauges on your dashboard.

I'm just getting back into shooting after about a 30+ year layoff.  AND...the addition of bi-focals!  Will be one of my retirement hobbies..!

So far, just the addition of the smaller, large field red dot sights help immensely.  You don't "look" at the red dot, you look at the target, and place the dot under the target.

So far, I've installed them on three of my hand guns, including my new CZ, P-01.

I gave up on bifocals. I gave them a try, twice, and they drove me nuts! I find even the "no line" ones annoying as hell. I bought a pair of "computer glasses" and they were a waste of time too, they were blurry and while they did make the monitor look slightly better, they made the TV, which I watch a lot while using the PC, look like a bad TV from the sixties instead of the high def it is. I ended up getting normal lenses put into the for a spare pair. I don't seem to have any problems seeing when I shoot, my back is my main issue. Unlike most of my friends about my age, I have zero shake. I have the steadiest hands I've ever seen. My doctor's hands shake, and he's only about 45 years old. No surgery for him anymore.

I "rang in" before on this Subject.  I am wearing tri-focal clear lenses as I touch type this message.  I can read newspaper if I want to without correction but I have some astigmatism and I wear eyeglasses for driving a vehicle--need the long range "distance" correction.  My every day glasses have two visible horizontal lines (and are tri-focals).  I use the middle range for my computer screen distance that is about the end of my clenched fist.  I can also see that my thumbnail has ridges that are visible to me.  I have attempted to explain that I wear a particular lens "grind" that I use for pistol open sights.  I use a different lens for pistols with red dots that I also use for scoped rifle use AND also for shotgun clay target use.  I do not want to talk about my RX because your mileage may vary.  I tend to not also post firearm powder load min/max or sweet loads for reasons.  Your health and safety may be important to you and people who like you.  I am standing down (off my box) but progressive lenses once drove me nuts, so to speak.
