Purpose. We compared with the refracting power and aberration according to the measurement change in illumination and the pupils area by using the auto refraction instruments. Methods. In this study it were examined 64 eyes without eye disease, 21.4 (${\pm}2.54$) age, 32 (male 10, female 22) patients. Experiments in general illumination using the auto refraction instruments (HRK-8000A, Huvitz, Korea) was measured in both eyes 3 times and after scotopic for 30 minutes in a dark room blocked the light was measured in the same way. Aberration were measured coma, spherical aberration, high and low order aberrations in a general illumination (3500 lux) and low illumination (5 lux) of the pupil area 3.96 mm and 5.96 mm. Results. In the general illumination for measuring of the pupil area, the refractive power, coma, spherical aberration and low order aberration was no significant difference. In the low illumination, spherical aberration of the pupil area was $0.005({\pm}0.015){\mu}m$ in a 3.96mm, $0.014({\pm}0.020){\mu}m$ in a 5.96 mm and appeared a significant difference(p = 0.003). In general and low illumination on the results of comparing the measured values of the refractive power and aberration at the pupil area 3.96 mm, high order aberrations was $0.205({\pm}0.145){\mu}m$ in general illumination, $0.132({\pm}0.075){\mu}m$ in low illumination and appeared a significant differences(p = 0.001). High order aberrations at the pupil area 5.96 mm was $0.278({\pm}0.244){\mu}m$ in general illumination, $0.150({\pm}0.092){\mu}m$ in low illumination and appeared a significant differences(p = 0.000). Conclusions. When the eye refractive power measured by the automatic refraction does not depend on the illumination conditions and size of the observation pupil area, it was found that aberrations are affected by the illumination and the observation pupil area. It was found that the eye examination chamber illumination to obtain accurate measurement produces better results to decrease than to increase.

국제표준직업분류나 일본·미국의 법률시스템, 양성시스템를 통해서 본 안과검사인력은 안과전문의, 검안사, 시능훈련사, 검안기사, 안과기사가 포함된다. 국가통계포털 자료에 의하면 2022년 안과에 근무하는 안경사의 수는 의료기관 종별에 따라 파악이 가능하지만, 임상병리사의 수는 파악이 불가능하다. 다만, 본 연구를 통해서 상급종합병원의 경우 임상병리사가 안경사보다 많이 근무하는 것으로 조사되었다. 우리나라 안과검사실 인력의 경우 국제표준직업분류, 국제표준교육분류, 의료법, 의료기사 등에 관한 법률 및 고등교육법에 비추어 봤을 때, 미국의 검안사는 비교 대상이 아니며 안과전문의나 검안사의 지도를 받아 업무수행하는 검안기사가 부합되는 직업일 것이다. 민간자격으로 대한안과학회 및 대한검안학회에서 안과검사실에 종사하는 임상병리사 및 안경사에게 '임상검안사'라는 호칭을 부여하여 새로이 자격관리를 정립한다면 국민 안(眼)보건 향상에 더욱 도움이 되리라 생각된다.

Purpose. The purpose of this study was to investigate the effect of lens color of sunglasses on stereoacuity by experiment. Methods. We conducted a stereotaxic test using a RANDOM DOT with a polarizing lens at an examination distance of 40 cm in 100 men and women aged 20 to 60 years without any specific ocular disease. Then, seven kinds of PVC color film such as yellow, black, brown, red, purple, blue and green were put on the polarizing lens and the stereoscopic examination was carried out again. Results. When the lens color of the sunglasses is yellow, black, and brown, it affects less stereoscopic effect. However, red, purple, blue, and green have much influence on stereoscopic effect. Especially, the red and purple colors affected the stereoscopic vision. In blue and green, the effect of stereoscopic vision was different according to the people. Conclusions. Depending on the lens color of the sunglasses, stereoscopic vision is affected, which can cause problems in binocular vision. Therefore, when choosing sunglass lens color, many buyers need to pay attention.

Purpose. In this study, The change of the accommodation function due to the use of a smartphone was objectively evaluated using an Auto Refractokeratometer and was to investigate the effect of accommodation response and microfluctuations of accommodation on stable fatigue. Methods. Twenty subjects (20 males, 20 females) who had no abnormalities in ophthalmic disease and strabismus, diplopia, suppression, convergence and ocular movement, and corrected visual acuity and unaided visual acuity of 0.8 or more were performed. The average age of the participants is (21.78 ± 1.78) years old. The refractive power of the eye was measured using an Auto Refractokeratometer (Speedy-i K-model, Righton Mfg Co. Tokyo Japan), and the equivalent spherical power was automatically calculated from the measured refractive power. The accommodation response amount was calculated for the accommodation stimulation amount in 8 steps in 0.5D increments from + 0.50D to -3.00D in the calculated equivalent spherical power. The microfluctuations of accommodation in the high frequency region was calculated according to the change in the amount of the accommodation stimulus. At this time, the spectral power of the microfluctuations of accommodation was analyzed by Fast Fourier Transformation (FFT). Results. After using the smartphone, it was found that the accommodation response to accommodation stimulation decreased and the microfluctuations of accommodation increased. Conclusions. It can be said that the use of a smartphone affects the accommodation response and the microfluctuations of accommodation, thereby causing a accommodative stable fatigue. Therefore, it is thought that the use of a smartphone for a long time may bring about a change in the accommodation function.

Purpose. The actual status of wearing toric soft contact lenses was investigated to learn why it is not used although it is required. Materials and Methods. This study has studied 64 contact lens wearing the local college students, Gyeongsangnam-do who are 20.17(${\pm}0.70$)years old, by measuring their refractive power and over-refractive power with auto refractometer(HRK-8000A, Huvitz, Korea). In addition to that, a survey was done to figure out why they do not wear toric soft contact lenses, the purpose of using toric soft contact lenses, whether they have astigmatism or any knowledge about it, the kinds of contact lens, whether they are willing to buy corrective lenses, and how they are satisfied after purchasing them. Results. 17 students (21.9%) said they experienced light-spread; 9 students (14.1%)said that they have dizziness when they wear contact lens all day long. In the survey to see whether they had astigmatism or not, 37 students (57.8%) said they had it. For the reason they do not wear toric soft contact lenses, 33 students (51.6%) said that "they were prescribed regardless of astigmatism in the optometrist." To the question asking if they are willing to buy toric soft contact lenses according to the existence of astigmatism, 51 students (79.6%) answered they are. 31 students (48.4%) said they heard a description about astigmatism at the time of purchase for contact lens. Conclusion. As the ways for any people who need to correct astigmatism to wear corrective lens, enough education about astigmatism and consistent follow-up management are needed, where the role of optometrist is considered important.

Contamination by pesticides is an everincreasing problem associated with fields of environmental management and healthcare. Accordingly, appropriate treatments are in demand. Pesticide detection methods have been researched extensively, aimed at making the detection convenient, fast, cost-effective, and easy to use. Among the various detecting strategies, paper-based assay is potent for real-time pesticide sensing due to its unique advantages including disposability, light weight, and low cost. In this study, a paper-based sensor for chlorpyrifos, an organophosphate pesticide, has been developed by layering three sheets of patterned plates. In colorimetric quantification of pesticides, the blue color produced by the interaction between acetylcholinesterase and indoxyl acetate is inhibited by the pesticide molecules present in the sample solutions. With the optimized paper-based sensor, the pesticide is sensitively detected (limit of detection =8.60 ppm) within 5min. Furthermore, the shelf life of the device is enhanced to 14 days after from the fabrication, by treating trehalose solution onto the deposited reagents. We expect the paper-based device to be utilized as a first-screening analytic device for water quality monitoring and food analysis.
