Purpose: The aim of this study is to grasp domestic eyewear trends in 2008 with analyzing brands, types, materials, colors and styles of new eyewear products. Methods: Examined all new eyewear products which were on three magazines related with eyewear published in Korea; "안경계", "Eye 11" and "THE AXIS". Results: There are 103 companies, 182 brands in 3 magazines related eyewear published in 2008. There are 77 domestic brands and 105 imported brands, and there are 522 eyeglasses and 126 sunglasses. Material of eyeglasses make up 37.93% of combination frames, 33.14% of metal frames and 28.93% of plastic frames and material of sunglasses make up 50.79% of plastic frames, 30.95% of combination frames and 18.25% of metal frames. From a style point of view, there are lots of retro and casual styles which one can express one's individuality with. In terms of colors, basic colors such as black and gray are mainstream and pastel tones and vivid tones are mainly used as the point color. Conclusions: The results of analyzing new eyewear products show that many light and feeling good products such as thin plate frames, TR frames and thin plate-TR combination frames were released in case of domestic eyewear products. In case of imports, there are lots of simple Ti frames and acetate frames which were variety patterns and colors.

This research was conducted to assist with domestic eyewear industry to gain better understanding of manufacturing through study relationship between purchase behaviors and selecting elements such as design, brand, price, material and nation. Domestic consumers think that the most important factor is a design when they purchase eyeglasses regardless of kinds and brands of eyeglasses, and optometrists choose the eyewear design as a primary factor when they buy eyeglasses for display and sale. As a role of eyeglasses for fashion items increases, the interest of the eyewear design will be higher. Many optometrists have plans to import and make house brand. Some of them also would like to study eyewear design.

The history of the glasses can say that we began with the development of the typography. Glasses were made for the first time from the skin which they tied. We came to make the rim as the horn tree afterwards or bone. And the snail glasses make the lens as the modification or glass and to put to connect the two to large snail was developed. The rim after he brought lots of style change. The development of the Bridge and eyewear form of the Temple of an entry today began to come out. The development of and various design and material. We reached practical style. development of design concentration new fashion trend lead can make it eyewear company and designer's. A rim of various style through historical development course because we have a present time's rim analysis. We try to try to investigate a method element of the glass design with a final cause form of the design in the viewpoint of the facility.

Most of eyeglasses manufacturers in Korea consist of relatively small-sized enterprises with less than 10 employees. In terms of scale, it performs considerably poor compared to other competing nations like Italy and the People's Republic of China. As a result, domestic eyeglasses industry is facing a difficult position between high-priced products of developed countries and low-priced goods of China, South East Asia, and etc. Considering these factors, the urgent solution for revitalization of domestic eyeglasses industry could be seen as major structural changes in eyeglasses producers. In addition, it is also noted that procurement of competitiveness is an essential scheme to reinvigorate the Korean eyeglasses industry. This objective can be achieved via improvement of ability to develop new designs, exploitation of new material and technology, intensification of own innovative brand and public relations, development of new products such as functional glasses, reduction of sample producing period, provision of administrative support, and designation of special economic zone.

Purpose: In this study, we evaluated the physical and thermal properties of the compositions made by blending glass fiber (GF) of different contents into glass fiber polyamide-66, and investigated if the compositions applying to the glasses frame to replace the TR-90, which is polyamide-12 resin used as an injection-type spectacle frame material. Methods: To investigate the characteristics change of polyamide-66 (PA-66) compositions with the change of the content of glass fibers, we produced a composition of the content by using a twin-screw extruder. The mechanical strength of the composition production was measured and coating properties as well as cutting processability were evaluated. We evaluated the applicability of the glasses frame by comparison the results of new compositions with characterizations of traditional TR. Results: For the results of the characterization of Polyamide-66/GF composition, we found that the higher increase of content of the glass fiber, the less mold shrinkage rate, and the mechanical strength was increased. Tensile strength increased from $498kg/cm^2$ for 0 wt% of the content of the glass fibers to $849kg/cm^2$ for 30 wt% of the content of the glass fibers. As a result of a coating evaluation, the strength of coating was 4B in the GF 5wt% and 5B, which was extremely good coating characteristics, in the over than GF 5 wt%. Conclusions: In case that 30 wt% of the glass fiber was blended, the mechanical strength was greatly improved, the hardness was increased, injection temperature increased due to increase of the viscosity, and the flow mark of the product may occur. The paint coating of PA-66 blended with glass fiber was all excellent. With general evaluating physical properties and workability properties it was determined that around 10 wt% of the content of the glass fibers was possible to apply a spectacle frame.

The results that research industrial competitive power of about two hundreds frames manufactures were as follows. First, It's researched that frames industry of Daegu will be worse and worse, and 79 percent of inquiry manufactures in export and 58 percent of them in the domestic demand prospects to be worse. Second, it is analyzed that the commercial profits in 2004 was more decreased to 16.5 percent than 2002. Therefore it is studied that they will be diminished to 5---- comparing with last year by a fall in the exchange rate of the won dollar, in the export unit cost and a raise of raw material price. Third, it is researched that most competitive countries of Daegu glasses manufactures is China and the mext county is japan, ltuly and hik. Fourth, It is studied that average price of glasses of Daegu during last three years(2002~2004) was more disadvantageous than China and Hong Kong, but was more profitable than Italy and Japan by the examination that when Korea is 100, China is 82, Hong Kong 89, Italy 112, Japan 114. Fifth, It is investigated that the average of production cost in Daegu is more disadvantageous than that of China and Hong Kong but is more profitable that of Italy and Japan by the study that when average production cost of Korea is 100, that of China is 78 and that of Hong Kong 89, that of Italy 114. Sixth, It is studied that the Average personal expense of Daegu is much more disadvantageous than that of China and more profitable than Japan and Italy by the analysis that when Korea is 100, China is 74, Hong Kong 98, Japan 112, Italy 113. Seventh, It is analyzed that technique, quality, design of Daegu are more advantageous than those of China, are equal with those of Hong Kong. Eighth, It is studied that Daegu still lags behind more four and five years than developed countries and goes more oheod four years than developing countries.
