Missfive Ultra Thin Folding Reading Glasses Men Women, Foldable Readers Lightweight Portable Pocket Flat Hard Case

Q: How wide are the frames? And length of the arms?

I have a wide head myself. The metal is so thin they flex easily.

Q: What is the total bridge width?

Hi, Thank you for contacting Missfive. The width of the bridge is 19 mm (3/4 in). Hope this help.

Q: What is the width and height of the lens?

Thanks for your inquiry. The length of lens is 1.9 inches (48mm) height is 0.91 inches (23mm), length of temple is 5.55 inches(141mm), and width of frame is 5.32 inches(135mm). Most importantly, the materials of the frame and temple have great flexibility and are resilient for all head shapes. You could buy them to have a try first, we promise 90-day money back and 1-year manufacturing defect warranty (free replacement/refund). If you have any other questions about the glasses, please feel free to contact us.

Q: Need different strengths for rt eye & left eye. Can I dissemble nose hinges of 2pr of yours, swap left side, & reassemble?

Probably. What's not shown in the picture is on the underside of the glasses on the small bridge piece there is a small screw that looks like it holds the front and back of the bridge together. So I'm assuming (I'm not taking mine apart), that you can unscrew that, free the sides and then re-assemble.
