As a life long glasses wearer I don't really agree there's a problem with the "better or worse" method. It's a pretty interesting implementation of bisection search and it's a very controlled environment. It's also a great example of how constraints (time) helps you arrive at a good answer without over thinking it. If you were out wandering the streets or looking at random things with no constraints you would be overwhelmed with choice and it would be very hard to draw a conclusion. You may decide what's right is based on looking at something, only to find out after all of that something else 4 days later looks way off because you didn't see that during your real world test. You end up being individually burdened with making the decision instead of letting science do its thing. The only issue I have is frames because it's very possible to get frames that are comfortable for the few minutes you try them on in the store but they end up being horrendously uncomfortable after a day or few days of usage (even after many adjustments). I don't know how to solve that problem though because in order to wear the frames for a long test period you would need to be able to see, which means your real lenses need to be placed inside.
