Making eye glasses with lens made up of quartz called Diyatharippu is a diminishing craft. It is preserved only by one family and, for obvious reasons, needs urgent safeguarding. Diyatharippu mineral is used as its raw material. This industry is not as popular as other crafts like brass or lace, but, like other craft industries, it also has a history as old as 14th century when Buwanekabahi IV, the first king of Gampola Kingdom, own a pair of Diyatharippu eye glasses.
