The Personal Vision Tracker is a fast and affordable way to conduct an eye “exam” at home. Depending on where you go, an eye exam can cost as much as $100. With the PVT, you can test and track your vision for a fraction of the cost and do it at your convenience.
The PVT is a small plastic scope that attaches to your phone and runs each eye through a series of simple app-powered tests. When you’re done, you’ll have the numbers you need to order glasses online, which can cost considerably less than what you pay at retail.
