Agreed all points on the optometrist helping you. Tell your eye doc what you want the glasses for and he/she can set you up. As most know I am a sponsored competitive shooter. My eyesight has deteriorated to the point of bifocals etc. not a big deal Told the doc how I wanted to use the glasses and he made me a set that work just fine. I call them my Mr magoo glasses! Spent all day today with a couple no neck SWAT deputies and one of them brought their wife. Worked on bounding and room clearing for six hours. Great day!
