Not sure how long it lasts; yes they had the Opus 1870.
When I used to work as an Optom Assistant in undergrad, I was under orders from corporate not to give out the PD's.
Still did it. Our mark ups were a fucking joke. Especially on plastic frames. At least the titanium frames had some tangible reason to be more expensive.
But PD's can be done DIY if you've got the frames, a friend with a marker, and a ruler.
