I am new to shooting (both pistol and rifle) and find myself facing a big problem: I cannot close my non-dominant eye.

The above is problematic because most often new shooters are advised to close their non-dominant eyes when trying to use iron sights to aim at a target. I am unable to close my non-dominant eye due to an injury I sustained in my youth. Please note that I actaully can close my non-dominant eye but NOT if I try to keep my dominant eye open.

What are my options?

Are there specific sights or optics that I could use with either a pistol (my current pistol being a Glock 19) or rifle (mine being an AK) that work best with both eyes open?

Or are there any methods for learning to shoot with both eyes open that any of you would recommend based on experience? I have seen various methods suggested for learning to do so but it appears that they are not all giving the same advice so I am not sure what would yield the best results.

At any rate, any and all help would be most appreciated.

Best.
