After having a concussion in Dec 2016, I had a lot of issues with balance, riding in a car, reading for any length of time, using a computer, etc. Dr Jong and her staff did a lot of tests, and came up with a plan to help me. Two years later, I can drive my car for short distances, I can ride in a car for an hour to an hour and a half. My balance is a lot better. While therapy helped, the prism glasses with tint that Dr Jong prescribed have pretty much been a miracle for me. They have made a significant improvement in my balance. The tint and prisms have improved my ability to read without overtaxing me neurologically and making me sleep after an hour. They cut down on the visual noise and have even helped my short term memory which was affected by my concussion. I can't say enough good things about Advanced Eye Center.
