Review on Optical Optometry Optician，Changeable Cylinder Adjustable by Mark Tarnowski

Works with UCanSee lens. The product will be shipped directly from China. It arrived on the first day of waiting, total delivery time: about two weeks. In addition, the product was inspected by JFK Customs. The product has many adjustments including headband, bridge, Pd and astigmatism axis. Using the UCanSee lens and these test glasses, I was able to identify a number of flaws in my current glasses as well as a new prescription from an ophthalmologist.
