It also has to be impossible for failure of the hinges to lead to damage of the electronic components. I've lost multiple laptops to hinges twisting in ways that they shouldn't have and fracturing the motherboard or keyboard, and that's in a form factor that gets much less abuse than glasses.

citation needed. For me, it's the scratches and the surface issues. Even though I have no problem taking care of my regular glasses for years, most of my sunglasses become unusable and hard to see through from deteriorating surface and scratches after 6-10 months. No matter if I get $30 or $300 ones.

Isn't that just sunglasses manufacturers simply cheap out on lens materials and coatings? I don't see what would be stopping VR/AR manufacturers from making quality lenses.
