Our eyewear industry, the recent growing its position has been weakened because of Chinese low labor costs, Japanese quality and technology and Italian excellent design, brand and marketing. Investigate the recent trend for the trade balance of China and Italia, the largest importer of the eyewear market in Korea. Sunglasses are the most vulnerable sectors of the eyeglasses industry in Korea. Continued investment and attention is needed to the eyewear design for the improvement of the trade balance.

This is a study of the measurement of inter papillary constance (P.D) in 702 old aged farmers (aged over 45) and the comparision of frame size and distance space of optical center (O.C) from 240 Ready-made Reading spectacles. The average of P.D in male (62.83mm) is greater than in female (61.18mm), and the O.C of Ready-made Reading spectacles of Plastic lens (71.2mm) longer than glass lens (70.8mm). The correction prism power by wearing Reading spectacles in male was 0.7prism to 3.6prism and in female was 0.9prism to 4.4prism. So the prism power in female is greater than in male.

HMD(Head mounted Display)는 보안경이나 헬멧 형태로 눈앞의 지근거리에 초점이 형성된 가상스크린을 보는 안경형 모니터 장치로서 예전에는 군사용 시뮬레이션이나 가상현실(VR-Virtual Reality)을 실현하기 위해 개발되었으며, 양쪽 눈의 근접한 유치에 설치된 1인치 이하의 LCD, OLED, MEMS panel 등 마이크로 디스플레이에서 발생되는 이미지를 광학시스템을 통해 확대하여 대형 가상화면을 형성한다. IT 산업의 비약적인 발전에 힘입어 휴대용 동영상 및 모바일 정보검색, 3D의 시대가 대두됨에 따라 휴대폰이나 PMP의 작은 화면으로는 만족하지 못하는 소비자의 수요에 적합한 개인 휴대용 모니터 장치로, 3D를 구현하는 안경형 모니터로서 향후 크게 형성될 모바일 산업의 핵심제품이 될 전망이다.

In this paper, the front radiuses of curvature of spherical spectacle lenses in the cosmetic and optical point of view are investigated and are calculated using Zinken-Sommer condition. The optical power of all spherical spectacle lens shows good quality at the test using autometic lensmeter. However the front radiuses of curvature of spherical spectacle lenses are quite different depending on the lens companies. The front radius of curvature of those lenses is larger than that calculated using Zinken-Sommer condition. We know that the front radius of curvature of commercial spectacle lens is emphasized more cosmetic aspect than optical point of view.

In order to analyze the difference of lenses production, we measured the refractive power and the thickness of their optical centers using ophthalmic lenses which were distributed at home country and abroad. The home products were manufactured to be next to foreign goods, but there were several cases to exceed acceptable limits and we need to reduce the deviation from measuring values in the same lenses. To get a beat on advanced countries, rearing technical expert, hard quality test and process control and standardization of lenses are essential to home lens industrials.

Vision is the most important sense of the five senses in our body. This represents that an eye is for the mysterious organ playing the essential role in our body. Alain Mikli known as a famous spectacle designer in France said that glasses exists for seeing and for being seen. This saying is one of the philosophically well-organized definition of the most fundamental function of eye-glasses described in and out of itself. Today, in the world, there are a number of works of glasses design and lots of glasses designers are designing hard in order to convey the goods with the best value and philosophy to customers. They work for the goal that glasses is used as seeing and try to give customers satisfaction and enjoyment of it. And they think that glasses should play the role of the interface. At this point, we need to catch hold of the interface of glasses. That means that glasses has to have the communication between eyes and objects and be the mediation of the connection between the image of oneself and that of one by others. For the character of the interface of glasses, glasses designers should plan and investigate this character at the being of design. This study of optical art has been researched for the necessary and sufficient condition between consumers and products.

Purpose : This survey aimed to investigate the differences in shape and color preference of eyeglasses and sunglasses between Korean and Chinese consumers. Methods : The questionnaire was conducted on 150 Chinese students studying in Korea and 150 Korean college students. Any student who majors in optometry was excluded. Chinese students were provided with questionnaires that were translated into Simplified Chinese characters, and it was translated by a native Chinese student studying in a master course of a Korean university, on the basis of Korean questionnaire. Results : The Chinese consumer group preferred the global famous brand in sunglasses rather than the glasses, and it was found that they preferred the Korean glasses products relatively. Also, they presented higher preference to half- or rimless frame, gold color, two-tone colored lens, comparing to the Korean consumer group. Conclusion : The results of this study are expected to contribute to Chinese marketing strategy of Korean manufacturing optical shop companies, and to sales strategy of Korean optical shops with Chinese tourists.

Purpose: The objective of the study: At present, the spectacles, with its use as a medical aids or a fashion trimming, are recognized as one of the living necessities which can't be separated from human body. One of the features of spectacles is that it must be worn on any part of human body. Such a feature has to be satisfied under the condition an user keeps feeling comfortable with the rim of spectacles worn. In order to ensure meeting this condition, a criterion has to be arranged for the design of the rim of spectacles. In order to manufacture a rim of spectacles which allows an user to secure a comfortable range of vision as well as enhancing the feeling when to be worn, a manufacturing standard has to be established based on optical science. No precise rim of spectacles could be made from the manufacturing method depending on the manufacturer's sensibility. When the rim of spectacles was manufactured according to the incorrect standards, it may cause an user such a fatal result as myopia, hyperopia or astigmatism. Methods: This study focuses on providing a detailed explanation about the design of rim, which is the most important element during designing a rim of spectacles, making use of the optical elements of spectacles, and helping the manufacturers and the people who work in the spectacles-related business understand and recognize what is correct and exact and then leading them to establish a standard in respect to the manufacture and selection of spectacles. Results, Conclusions: Considering the fact there happen many errors in relation with the names of rim stipulated in the provisions of International Standards Organization (ISO), due to wrong interpretation by some of the rim manufacturers, the right interpretation should be given about the bridge which is directly connected to rim, so that the rims of spectacles manufactured in Korea could keep a favorable position in competing with the foreign products of same kinds.

There are many functions of glasses. Not only as a medical instrument but also for decorative purpose and individuality as a mean of expression. The concept of glasses applied according to various purposes and use. Following the designers' point of view, the most important research task is to make products substantial and convenient rather than external beauty after analysis problems and the needs of customers. Because customers ask for the best quality of design all the time. The best design of glass includes essential conditions like; creativity, satisfaction, convenience of use, identity. These conditions are common elements of glasses in both domestic and foreign markets. Also they can be a catalyst to stimulate glasses industry in Korea. First of all to study tho parts of glasses "End Piece", it is essential to consider for a better design. Because it adjusts the center of glasses weight balance for user's comfort. Since many brands are imitated, the significance of "End piece" is of a great importance resulting in a more successful competitiveness.
