The problem is, the human eye isn't physically able to do so which is why one of the 3, normally the rear sight, is blurred out. This can and will lead to problems.

With the peep sight, the eye will automatically center the front post in the middle of the ring and if it adjusted correctly in regards to elevation and windage all you have to do is put the tip of the front post where you want the bullet to go. Your eye only has to focus on 2 things, the front post and the target, which it is capable of doing. There is a reason the military uses peep sights on their battle rifles, they work better than open sights. if they didn't, the rifles being issued would have open sights and they don't.

I've hit man sized target at 300 yards with my issued M-4 with a peep sight and I know for a fact I can't do that with open sights.
