Human: I've been searching for a new pair of sunglasses, but I'm not sure where to start. Assistant: 
You can begin by doing some research online or asking friends and family if they have any recommendations. Once you find something that looks good, read reviews to make sure it fits your needs and budget. Consider the size, shape, color, and style of the glasses before making a purchase. Make sure to also check return policies in case you need to send them back.
