I use my readers as my prescription glasses. I have the lense removed and the local optical store puts my scrip lenses in. I usually keep a backup should they break. This time when my glasses broke, I went for my backups and noticed they were broken too. I was able to epoxy them together so I could have glasses. I quickly ordered new Lydia's, prepared to wait a week or so. Imagine my delight when new Lydia's arrived just 2 days later. Thankyou iheart.
