Buy a new sight with a fiber optic ring around the guard so you can see it in low light.
It's not the pinguard that I can't see, it's the peep itself. geeezus, some people and their refusal to read!
jk, that might help but a little though it's a good point that I be able to see all of the necessary alignment components as clearly as possible.
Or...
Do what I do. Forget the flippin' guard and center the pin in the peep.
Already did that and said I did that too but found the current method much more accurate. I think Jeff hit the nail, it's just a product of the chosen method.
Maybe it's time to try something like a HindSight.
