Yes I believe in the mantra as well however you will hardly convince me this applies to a frame and lens. Yes it may be less time consuming for the purchaser to just grab a entire new pair off the shelf but someone had to dig out the ore to get to the metal to and someone drill out gas to move the ore around and so forth you get the point. As we know global climate change is real, and I have children who I leave this earth, surely on a global scale, me replacing the glass in a frame is less wasteful for everyone's time. But I only reply because you said 'human time' vs something like 'if it saves my time'. Most of what we consider to saves our personal time is at a considerable cost to the environment, and other peoples time. We destroy the environment so my kids can spend their time cleaning it up in the future. What a screwy way to live.
