Thank you for dropping by our booth at the MIDO fair. It was huge responses of our products, such as Bi-focal Poalrized photochromic lens and Tri-S polarized lens. With speical technology, we combine polarized photochromic and reading function perfectly. For Tri-S, the special layer after mirror coating can protect mirror perfectly for sea water resistant, better scratch resistant, and acid resistant. We are able to develop new products every year and stabilize production with high quality. As expected, there were lots of people visiting our booth during the fair. You might not have enough time to really take a look at our new and more outstanding products. The website has included herein our new catalogue. Please take time look at our products !
