Google 'eyepal' then make your own using a piece of black insulating tape and a thick needle.
Poke a hole in the tape, or even better, melt a hole in it. About 2-3mm is enough, but you need to experiment.
Stick the tape on a pair of safety glasses if you shoot without glasses on.
Make sure the hole is perfectly aligned with your eye when in your shooting position.
The tiny aperture of the hole messes with your depth of field, bringing the front sight, the rear sight, and your target all into focus at the same time.
Great for open sights.
