SAV Tri-Focus Unisex E2201 Tri Focus Reading Glasses - Flexible, Durable, Lightweight, High-Performance Readers

Are these frames a soft plastic like the Flex 2 frames?

what is the prescription power on the top portion ? Is it plane clear lens on top ? If yes, then does it mean we can wear it all the time right ?

How do determine the size of the frame?

Do these have the same blur spots as progressive lenses?
