This is a study of measurement of inter Reading Pupillary Distance (P.D.) in 729 old aged farmers (aged over 50). The average of Reading Pupillary Distance (P.D.) in man (58.93mm) is bigger than in woman (57.82mm), and the O.C. of Ready-made Reading Spectacles is 68.98mm.

We studied the Malus's law for two and three polarizers experimentally. It was satisfied for two polarizers such as ${\phi}=cos^2{\theta}$, for three polarizers such as ${\Phi}=\frac{1}{4}sin^22{\theta}$.

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%.
