Hope everyone is well. Went to Lenscrafters today to send my Mag Four frame out for prescription lenses. They stated the lab won’t be able to properly size the lens since I’m missing the one of the screws that’s inserted at the bottom of the frame. Please see pictures. I’d be most grateful if someone could guide me to the specific type & size/dimensions of the screw I would need. There also looks to be a rubber washer inserted too. From research online, I’m guessing it looks like a torx t4 screw & there’s a bunch of screw kits on Amazon for purchase. Thanks in advance for any guidance.
