We bet you didn't know you can have an eye exam and get outfitted for frames and lenses, all during a day of shopping at KOP.

If you're tired of hunting down a fab pair of frames and filling a new contact prescription, rest easy. King of Prussia Mall is where you want to be. With plenty of optical stores, duck in for an eye test in as little time as it takes to do lunch. Then shop around, swing back for your new glasses, and leave with a brand new look. Check out these one-stop optical stores:

Dr. Gary Kirshner has been practicing here for 25 years. Schedule your yearly vision test, and if you're ready to give up the lenses, look into Lasik; he does pre-screenings, and can set you up with an area ophthalmologist to do the surgery.

If you're looking for all the top designers-including Tom Ford, Gucci, Chloe, Jimmy Choo and Chanel-this is the place to be. Take a vision test, get prescription lenses for your shades and score first dibs on exclusive frames.

In just one hour, your whole family can walk out with new frames at either of these eyewear emporiums. They're known for carrying fashionista favorites like Tiffany & Co., Ralph Lauren, Versace, Dolce and Gabbana, Bulgari, and Prada.

Looking for a good buy? Head here for quality frames, sunglasses and lenses that give you a fashion-forward look without the designer price tag.

An optometrist is on hand to give you a comprehensive exam and promote good eye health. There's also a well-edited selection of up-to-the-minute frame styles at all price points.
