I agree with that Topgun. I can still see well at distance due to Lasik but don't ask me to read off a menue without reading glasses. Strange as it may be I can still shoot well through iron sights but I have to paint them for a contrast. Here is one that I use once in a while when in the big woods like Maine or northern NH and Vt. it is a 7600 aught 6 with a Williams peep and a firedot front sight. Still can pick that up especially when it is aimed a big dark brown deer running through the snow. I always use a scoped gun out west though.
