We love these trays an have been using them for years in our Dental practice. They hold up amazingly after years of autoclaving they still look like new!
I needed the prism to help a patient deal with diplopia due to a sudden onset of convergence insufficiency. After three days of getting used to 15 PD of prism, the patient came in smiling, with no complaints of diplopia at near or distance. The delivery of the prism was fast, the application of the prism was easy, the patient was happy! (So am I).
Great price for a great product, this is the best price I have found for Fresnel prism stickers. The patients at our opthamology clinic are satisfied with the performance of the sticker and the opticians are happy about the price and how east it is to apply to the lens!
