I see it is your first post, so
WELCOME!
I've seen an ad for the hex sights some months ago in a magazine, and if I recall correctly they are similar in principle to a peep sight. Here is a link to the product:

At age 56, I can no longer see the front sight clearly but the
Merit Optical Attachment works great for target shooting. It works using this principle:
The human eye, whether or not prescription glasses are required, cannot focus on both sights and the target at the same time. The eye will constantly shift focus from the sights to the target trying to ensure proper alignment. Unfortunately, as we age, the eye loses the flexibility which allows it to do this; thus, sights and target begin to grow fuzzy.
There is a simple way to combat this by increasing your eyes' depth of field (range of focus). If you look through an aperture or pinhole of the correct size, you will be able to see both sights clearly, and the target will be clearly defined as well. It was utilizing the principle of a pinhole that allowed the original box camera to work without a lens, and its pictures were in clear focus from about 2 feet out to infinity.
I don't know how large the hex sights aperture is, but if it is too large then it will be of little help to aging eyes. The Merit Optical Attachment aperture varies from .022 in. to .156 in. diameter. If it is much bigger than that, then it does not help bring the front sight into focus.
I mentioned "target shooting" above. For the aperture to be small enough to help the focus on the front sight, it is too small to be useful when shooting IDPA or in a self defense situation.
