Purpose - In recent years, new retail innovations have emerged in the Japanese eyeglasses industry and grown as a retail format. The purpose of this study is to establish the process model of retail format creation by examining how a retailer creates a retail format and under what kind of environmental conditions. Research design, data, and methodology - This study pointed out the weakness of the concept of the retail format in existing research on the retail format in existing research on the retail format variation theory and suggested the concept of "Formula" to analyze an individual retailer. This study categorized the subjects categorize the subjects of retail format creation into four categories, and analyzed JINS which is the retail format leader in the Japanese eyeglass industry. This study used secondary data because it is valid. Results - This research found "product handling skill," "changes to consumer purchasing patterns," and "competitive interaction" as environmental factors influencing retail format creation. This study highlighted how JINS adapted those environmental factors to create their original formula and suggested the process model of retail format creation through the JINS case study. Conclusions - This study discussed two theoretical implications and three managerial impressions which were derived from the JINS case study. This study also discussed limitations and further research issues.

Purpose: To investigate the UV-B blocking rate of eyeglasses lens which can prevent enzymes denaturation in cornea. Methods: The denaturation degree of RNase A and catalase, superoxide dismutase (SOD) was determined by using Acrylamide gel electrophoresis after UV-B irradiation of 312 nm for 1, 3, 6, 24 and 96 hours. Also, the inhibitory effect of eyeglasses lens having UV-B blocking rate of 50%, 80%, 95% and 99% on the enzymes denatration was measured. Results: The denaturation of RNase A was induced by 1 hour-irradiation of UV-B. To inhibit RNase A denaturation after UV-B irradiation between 1 hour and 6 hours, UV-B blocking lens of 95% were effective. UV-B blocking lens of 99% suppressed the inhibition of RNase A denaturation after the UV-B exposure between 24 hours and 96 hours. The denaturation of catalase was not induced by 1 hourirradiation of UV-B. To inhibit enzyme denaturation after UV-B irradiation between 1 hour and 6 hours, UV-B blocking lens of 50% were effective. UV-B blocking lens of 95% suppressed the inhibition of enzyme denaturation induced by UV-B irradiation between 24 hours and 96 hours. The SOD denaturation was not induced by UV-B irradiation shorter than 6 hours exposure. The UV-B blocking lens of 50% could inhibit SOD denaturation after the UV-B irradiation for 24 hours. When SOD was exposed to UV-B for 96 hrs, SOD denaturation was inhibited by eyeglasses lens with UV blocking rate higher than 95%. Conclusions: The results demonstrated that the proper UV-B blocking rates of eyeglasses lens to inhibit the enzymes denaturatioin was different according to the types of enzymes and its inhibitory effect was effective only when eyeglasses lens had higher than certain UV-B blocking rate.

This study examines the influence of women's appearance decoration on professional image, preference evaluation, and inferences about age and job. For the purpose of this study, women's appearance decoration was limited to eyeglasses, earrings, hair length, and clothing color. A quasi-experimental method was used for this study. The experimental design was a $3{\times}2{\times}2{\times}4$ (eyeglasses${\times}$earrings${\times}$hair length${\times}$clothing color) factorial design. The model of stimulus photographs was a woman in her late twenties. She wore a tailored collared jacket with a white dress shirt. The subjects were 362 female college students residing in Seoul. The results of the research were as follows. First, the woman wearing glasses and earrings was perceived as more professional than the woman without glasses and earrings. The woman with short hair was evaluated to be more professional than the woman with long hair. Light grey and dark grey jackets enhanced a professional image in the woman than red and dark red jackets. The woman without glasses was preferred more than the woman wearing glasses, and the woman wearing earrings was preferred more than the woman without earrings. Second, the woman wearing wire-rimmed glasses, earrings, and grey jacket with short hair was perceived to have the highest level of professionalism. Third, the subjects perceived the woman wearing wire-rimmed glasses as looking the oldest and the woman without glasses as looking young. The subjects perceived the woman with short hair as looking younger by 3 to 4 years than the woman with long hair.

Purpose: This study was performed to investigate the actual state about ultrasonic cleaning of soft contact lenses in local optical shops and evaluate the removal effect of protein deposit on soft contact lenses with different lens containers by ultrasonic cleaner for eyeglasses. Methods: The actual state about ultrasonic cleaning of soft contact lenses was surveyed in total 75 local optical shops in Seoul, Korea. The cleaning efficacy of different lens containers was compared by measuring the protein remained on ocufilcon D contact lenses after washing by an ultrasonic cleaner for eyeglasses. The changes on surfaces and wetting angles of ocufilcon D contact lenses by repeat ultrasonication were further investigated. Results: The main purpose to use ultrasonic cleaners in local optical shops was rapid cleaning. The ultrasonic cleaning efficacy of ocufilcon D contact lenses with glass containers was little higher than it with plastic containers, but was not significantly different. The changes on surfaces and wetting angles of ocufilcon D contact lenses in a plastic lens container by repeat ultrasonication such as 30 and/or 60 times were shown. Conclusions: There was not significant difference in cleaning efficacy between glass and plastic lens containers. However, repeat cleaning with ultrasonic cleaner for eyeglasses would be carefully considered since some significant changes in the parameters of lens surface and wetting angles were detected by repeat ultrasonification even when lens containers were used for ocufilcon D contact lens during ultrasonictions.
