Eyes: As I get older my visual acuity is not improving, although my distance vision is still good (had PRK done 20 years ago). I have started wearing clear shooting glasses, which cause my pupils to close down and let me see a crisper sight image (I am running an Aimpoint 2MOA ML3 on my rifle and fiber optic irons on my pistol/shotgun). Although I have several nice pairs of Oakley sunglasses, I stopped buying expensive clear glasses as they do get scratched up from time to time. Instead I find the Howard Leight brand to be a perfect fit for me, and the price ($10) is definitely right. When they get scratched in my field of vision, I simply replace them and relegate the old ones to secondary use.
Ears: I wear Dillon HP1 muffs over custom-molded in-ear plug (molded without the string loop so as not to touch the inside of the muffs). Not a fancy arrangement but very effective. The HP1 ear cups are slightly relieved to work with shouldered long guns, and the plugs give me added protection if the muffs do shift during a stage.
