The importance of Digital Transformation (DX) technology has increased with the Fourth Industrial 
Revolution. At the same time, research on defect detection and classification in the production process 
through artificial intelligence has been actively applied. In this paper, we select a model that effectively 
detects defects that occur in the production process of color contact lenses using various models, 
secure reducing resource waste and consumer safety by improving production and quality. For this 
purpose, data for training and validation were generated through preprocessing and augmentation of 
color contact lens images, using CNN technologies such as ResNet101, GoogLeNet V2, GoogLeNet V4, 
DenseNet121, MobileNet compared and analyzed the defect detection rate for each RGB channel and 
HSV channel. The accuracies of the above models are 89.74%, 84.46%, 95.43%, 82.80%, and 89.74% 
respectively, with GoogLeNet V4 on the RGB channel having the highest defect detection accuracy, and 
in most models, the RGB channel is higher than the HSV channel.
