Q: 9. I'm considering these for my Mom. She wanted some theater glasses stronger than normal. Are these too big to fit into an evening or small purse and/or do you know if they come with a cord or anything to go around the neck? Any other items you recommend I buy along with these?

A: My Mom likes hers. They are approximately 4.5 x 2.75 when opened up, and the barrels are 1.75 at their beltline. The bag they travel in is 4.5 x 6 when laid flat. I don't think there was a chain, but we got a matching brass chain. So they are very nice opera glasses, stronger than the usual glasses. One thing, we had to put a little bit of medium thread lock on the set screw to keep it from working loose--easily done. Can't think of any other accessories that would be needed.

Q: 10. Can one eyepiece be focused to better match eye differences?

A: Agree with the previous answers.
