The occurrence of glasses sales transactions at Indah Optical Optical, meaning that the company's transaction data will increase. If left unchecked, glasses sales data will become meaningless rubbish. Thanks to advances in technology, the ability to collect and process data continues to increase. Therefore, this research aims to apply the Apriori algorithm technique at Optik Indah Optikal to identify the most common glasses purchasing patterns that occur in stores. The association pattern calculation is carried out by first determining a minimum support of 4% and a minimum confidence of 5%. The test results obtained from testing the accuracy level together with the lift ratio calculation provide product combination rules that can be used in marketing strategies to increase sales by compiling product itemset packages to be purchased by consumers simultaneously. Established patterns or rules help consumers determine which products they want or which main products consumers are interested in. If the minimum support value is 4% and the minimum confidence value is 5% then the rules formed are 76 rules. From the rules, item pairing rules are formed with a support value of 4%, confidence 5% and a lift ratio test value of 99.6, which is the highest test value.
