An eyeglass lens processing apparatus for processing an eyeglass lens includes: a processing chamber inside which a lens grinding tool is disposed; a tank which stores grinding water; a drain hose connecting the processing chamber with the tank; a filter for eliminating bubbles attached to an outlet of the drain hose, which includes a large number of pores having a size such that permits passing of processing debris stemming from rough processing and inhibits passing of bubbles larger than the processing debris.
