Works only to make money at the cost of eyes health. No after-sale response, no return policy told to patients. At any eyeglass complain said to upgrade to digital lenses and no guaranty of fixation of problem. The worst experience of life. Charged money for photo/film without information and did not give the copy. There are many products that are sold to make money and are cheaper at Amazon, eBay. Charged money from diabetic patients. Only concentrates to sell the products which, if do not work will ask to upgrade. My vision is damaged. I see circular things oblong like eggs. Only one part of the progressive eyeglasses work for only distal vision. He must concentrate on the health of the eyes.
