The spectacle consists of a lightweight, yet durable plastic and is very pleasant shaped so that one even with long films eg 2.5 hours + not really get a sense has to wear glasses.
This makes the glasses are relative thick eyeglasses for as they are also easier to clean or not as sensitive as the standard of the polarizing filter glasses.
What's more, these are the glasses bent and thus not produce the typical window frame if something looks to the left or right.
To the eyewear design, I find this absolutely does not look like a 3D glasses out;)
