Lost blue Ray-Ban glasses near River Market

I lost my blue Ray-Ban rectangular glasses yesterday around 3pm. They’re blue rectangular frames with silver temples, and there’s a tiny scratch on the upper corner of the left lens. They came in a black leather case with a red lining, and the inside pocket has my initials 'P.K.' scribbled on a small tag. I was wandering around the River Market district on Clinton Ave in Little Rock when I last remember having them. They’re really important to me—they help me work, and they were a gift from my late grandfather, so I’d be grateful to get them back.
