What I do is buy the frame with cheap lenses to check fit, then I buy it with nice lenses if I like it. They are so cheap there is no reason not to do it this way.
Even ordering multiples it ends up being inexpensive.

Besides the environmental cost, maybe.
It is important to focus on effective actions. For example, a lot of people think that somehow recycling affects climate change, which (AFAIK) is not true in any meaningful sense. That isn't to say one shouldn't recycle -- there are plenty of reasons to do so in many cases.
I'm not saying this is the case here because the original pair of glasses can still be used, but isn't avoiding this kind of behaviour a good thing?
I don't have any idea about plastics/papers.
I'm not aware of any plastics that are recycled in to the same form. I know that PET (1) and HDPE (2) are recycled in to fibres.
It's a similar story to glass, certainly where I live a large amount of glass is recycled in to crushed aggregate rather than new bottles. The energy costs of cleaning don't make it worthwhile.
Consumers didn’t like it because scratches accumulate on the outside of the bottles.
Now that I'm in my mid-40's, I take it all back. Having a pair, even if it isn't the exact right one, always with reach is a godsend.
Decades later those NHS 524 frames became all the hipster (and Morrisey) rage. For hundreds a pair. Sometimes using original repolished frames as apparently they were well enough made to last forever.
That would make you all the rage in a hipster circles.
I would expect none of my data - profile, passwords, or banking info - is safe with them.
I bought three complete pairs of eyeglasses for $105 total, delivered. If you can be patient, about once a year, they'll run a buy-two-get-one-free sale. I now have prescription sunglasses, distance-only, and a set of hidden-line ("transition") bifocals. All with low-reflection coating, and high refraction index plastic. All three are holding up well after three years.
There was a very limited selection of glasses that were available for the 2-for-$60 promotion, and they really tried to upsell me to more expensive frames and lenses. Luckily I was able to resist their sales attempts and bought a nice frame and lenses from Zenni Optical. I keep one pair of the cheap glasses at my office and the other in my car.
As an aside, being able to get inexpensive glasses online has been a huge improvement on my life. I remember growing up when I only had a single pair of glasses (and a "backup" which were with my previous prescription). I had to be very protective of my glasses, and getting a scratch on the lens meant that I was stuck with it until my prescription changed. Now I can get my favorite glasses from Zenni for $25, so I have backups if the lenses get scratched or the frame get bent. I also have prescription sunglasses for the first time! No more dorky clip-on shades!
