Generic case included. Not sure what the prescription on the lenses are. Great preowned condition. Please feel free to buy multiple items with the confidence that I do offer combined shipping. If there is any problem with any item I sell I hope you will be willing to contact me before leaving feedback. Each item is listed after I inspect each for any possible flaws. I do make mistakes so please feel free to contact me and let me know. I usually answer questions very promptly so send me messages about any item. I will consider any REASONABLE offer. Thank you.
