I too got glasses for the first time. I was convinced to try progressive lenses for my regular glasses, but chose bifocals for sunglasses. I did insist on high quality optics with anti scratch and anti reflective coatings.
I was used to wearing a 'wrap' style lense, but found they were not available in RX except from Oakley. That was okay as I wore Oakleys anyway, but found they do not offer a bifocal in the M Frame. Also, the cost of an M frame with two different color lenses and the frames was about $700.00.
Currently, my vision does not really require the three zones of a full progressive lense, so I would probably opt for a lineless bifocal. The reason the NYX looks interesting is due to the fact you can still have multiple lenses to use with the single RX insert. My concern with this type of system is the fact you are looking through two lenses, the corrective RX insert and the colored lense.
Has anybody using the RX insert noticed any visual clarity or distortion with this arrangement? It seems it would be difficult to to get the curvatures of the two separate lense the same. Also, did the RX lenses come back as good a local optical lab ?
Are there any other options being used by R/C flyers ?
