By applying the test methods of "Protection Eyewear Standard (KS P 8147)", "Glasses Frame Standard (KS G 3306)" and "Lens Standard for Sunglasses (KS P 4404)", this study analyzed optical functions of sunglasses now being sold in a road shop (A shop), a fashion goods store (B shop), a shop of highway rest area (C shop) and an optical shop (D shop). When compared with sunglasses (UV transmittance rate 8.8%) of a road shop, UV Block effects of sunglasses (UV transmittance rate 0.7%) of an optical shop showed good results. In addition, the average surface resistance against abrasion for sunglasses which was sold at an optical shop was 1.4% that was much higher than that of sunglasses of a road shop(2.2%).

In this study, the results were that the duty of optician was analysed with DACUM(Developing A Curriculum Method). Task/Skill Matrix was formed and selected the elements above 2.15 points with the job description. The job specification made out the job description and the preference survey for the optician with the job model. These elements made a draft of drawing up standard of the Optician National Licensing Examination by Job Analysis.

The rate of transmittance of the sunglasses sold at home is shown in this paper. Most of the lens treated with sunglasses turned out to be 0% in the range of the UV, but those made by some company to be 18%.

Purpose: We have studied the problems associated with increased number of ophthalmic optics students and its effects on the supply and demand of optician. Methods: We collected data from Education Statistics, a white paper of Minister for Health, Welfare and Family Affairs, academyinfo web site and University (College) web site. Results: We forecasted an estimate for supply and demand of optician using the entrance number of ophthalmic optics. Conclusions: The numbers of produced optician are in excessive supply. The excessive supply of optician can contribute towards worsening working conditions and lower job satisfaction of an optician. Therefore this can result infrequent turn over of jobs within the same field and migration into the different field of areas. To solve these problems, we will need to act with the manpower policy of government by gathering the voices of the related optician agencies. Then expansion of job domain, improvement of quality level, the improvement of the working conditions for optician can be accomplished by the unification of university system and reduction of entrance numbers for department of ophthalmic optics.

Compared visual acuity that is measured in a artificial myopia with the numerical calculation. Calculation included image's height as well as blur circle that is formed to retina. The blur circle calculated in geometrical optics model, and height of retinal image calculated by refractive power and visual acuity that is measured in a artificial myopia. Define this result as "blur ratio" about blur circle and height of retinal image, and investigated blur ratio relationship about visual acuity in a artificial myopia.
