Blue-lid contact lens case with star sticker

Yesterday around 3pm I realized my small contact-lens case was missing after I left the Starbucks on State Street in downtown Chicago. It's a tiny, clear plastic case with a blue screw-on lid; the lid sports a tiny silver star sticker and the words Bausch & Lomb are faint on the side. The case is a bit scratched from daily use, and inside I keep a small silica pack and my prescription initials handwritten in blue ink. I wear contacts daily, so losing this is a real hassle and I really need it back—I'll be grateful to anyone who finds it.
