Re not having good eyes, that front sight as it is doesn't help.

Firstly, polish the brass bit of it as it helps to see it.

Secondly, when you get your new sight, if you file it at an
angle of 35 - 45 degrees and then polish it, the light will reflect straight back down the barrel at you making it easier to sight.

In addition, at that angle the sight picture stays the same
where as with a round bead, depending on where the sun is can change your sight picture without you knowing.

Hope that helps.
