Personal mistakes in testing, packing lenses and printing powers are realistic problem for all manufacturers, few personal mistakes are always there, even few percentage of mistake is allowed in many quality control standards. With this kind of mistake, distributors, wholesalers, retailers, even consumers are facing lots of trouble, they may need to test lenses piece by piece again and find out discrepancies. Is there any solution in avoiding this kind of personal mistake? YES! Y & S Optical Division established its new power testing and marking systems since late 2005, after few-month-testing and adjusting during their daily production, they have started to test all single vision lenses and print covers with these systems since Apr. 01, 2006. Response from various customers all over the world are very encouraged.

With this kind of system, after putting a lens onto computerized lensmeter (NIDEK LM-970), data will be transferred to computer and processed by the built-in data base automatically, then power and descriptions will be printed on lens cover immediately by the printer. In this way, personal mistakes have been avoided in max. level.
