Can i have prescription lense installed

I got these new, yesterday, I opened em up today, but the lense was really wobbly, I tried screwing it tighter, but it wouldn’t budge, any advice???

Can I put prescription lenses in the flip up sunglass layer?

Does the leather case come with a clip to attach to pants' or skirt's waists?
