Description
Internal-stress-free PC lenses:
  • Because the raw material of PC lens is crystalloid of polycarbonate, temperature and density will effect the quality of injection. Our company did a lot of researches on such elements and successfully found the most advanced resolving technology. Based on the date from China Testing Center of Opticla Lenses, Dongbao can prove its superior quality. (Dongbao’s PC lens eliminates the ‘rainbow effect’ in the essential lens area from optical center to 2.5 cm of the edge).
Double deck reinforcement technology in PC lens:
  • The new technology of ‘Double Deck Reinforcement’ in Dongbao’s PC lenses ensure that the surface of the PC lens can undertake over 1000g’s scratch, while most of the other PC lenses can only take 600g’s scratch.
