I sit at a desk every day, and I notice such terrible headaches around 3 p.m. I decided to give these a try, and WOW! The glasses are quirky and fun, very 70s vibe, in my opinion. They are comfortable, and my headaches are gone! They've helped my work days so much, plus it's a great accessory to add to an outfit. For the price, this is such an accessible fix!
