Yep, I use em (carbon fibre version) very happy with them.
Lightweight and by far the most comfortable pair of glasses I have.

 

I went with my 540’s because I didn’t want the inserts either for my prescription glasses. They have an unobstructed view, super lightweight, and never slide down.

 

Thank you that’s what I wanted to know. During my shooting career I have just used my prescription photo gray glasses. Now the hard part figuring out what colors to buy.
My optometrist who I have known for years, told me I was his toughest patient because most of his other patients could not see the the minute differences in perceptions.

 

I love Pillas, but the inserts rub against my eyelashes. Since I need a prescription now I went with Ranger Edge as I had to buy at a distance and it was the least expensive option. They are okay, but for my eyes not as nice as Pillas which I used to wear. I’d love to try the 540s, but I need to try a pair on before buying and no anywhere near me carries these frames. That, and the cost of new lenses every few years, has stopped me from buying them. I’m due for a new distance prescription and don’t know what to do.
