Unfortunately the frames do not fit. I am trying to get used to the prescription with the sunglasses I ordered before I try to exchange the clear lense pair for different frames. Thank you, Rodney

slides off my nose a lot when I am working for long periods of time

Having transitioned from a smaller frameless set of glasses, the size of these took a bit of getting used to. That said, now that I'm used to them, I like them a lot and have received lots of compliments on how they look. I went with the mid-grade lenses with blue light protection and am reasonably happy with them. Had I to do it over again, I would have gone with the more expensive, thinner lenses due to the fact my prescription (-4.5) necessitates coke bottle thickness in the cheaper lenses. This makes them a bit on the heavy side. The nose pieces are integrated into the acetate frame and do tend to slide a bit once my mug gets sweaty, so they probably aren't the best to wear to the gym. Otherwise, they have swag for days.
