because I didn't want to use my glasses for vanity reasons! With the front and rear apertures I didn't need them at reasonable ranges where I could still see the bullseye,
The problem with corrective lenses is that they sharpen one distance by sacrificing the ability to focus at another. That's the beauty of wearing an aperture on your shooting glasses. By filtering off-axis rays it improves close-up vision without changing your ability to focus at a distance. The caveat (and there always is one), other than having to align the aperture correctly, is that you lose some light, so this doesn't work well in dimly lit situations (which is the reason it's harder to see in the dark, your pupil is open wider and your eye's aperture is increased). However, for daytime outdoor shooting the aperture works great.
