Purpose : The purpose of this study was to survey on the wearing glasses and refractive errors in GP contact Jens user. Methods : we evaluated the refractive error and wearing conditions of the GP lens of 80 patients(male 18, female 62) from February 2006 to April 2007 on the Eye Clinic of K Hospital. Results : GP contact lens wearing time were daily over than lOhours 90%, 5 to 10hours 8.7%. 2 to 5hours 1.2%. Wearing time a day of have not glasses were 13.10±1.26 hours, wearing time a day of have glaases were 12.45±1.34hours. GP contact lens wearing time more Iong than wearing time have not glasses. Only contact lens wearers were 25% without eyeglass. difference of refractive error and spherical value of glasses were larger values of contact lens user than novice. Difference of refractive error and spherical value of glasses were larger vaJues of GPiens user in over one year than GPlens user in within one year. Conclusions : ln these results, majority of contact lens user were not recognized need corrected eyeglass. we knew that exchanged not glasses more Iong time GP contact lens users, accordingly, have not eyeglass were needed to educate thal contact lens wearer have to corrected eyeglass.
