After we compared the corrected len3 and the dominant eye who were wearing eyeglasses, elementary school in Iksan, we could get conclusions like these. 51 persons of the whole number, 65.4%, have the dominant eye of right. The refractive correlation to the spherical lens and astigmatic lens are the high non-dominant eye.

사람이 현실에서 공간감과 거리감이 있는 3차원 세계를 인지하고 주변 대상들과 상호 작용을 하면서 생활하는 것은 너무나도 자연스러운 것으로 받아들여지고 있습니다. 그러나 지금까지 현실 세계의 정보를 전달하는 영상 매체는 모두 평면적인 2D 영상에 머물러 있었으며, 3DTV는 기존과 달리 현실과 동일한 3차원 입체영상을 TV방송을 통해 전달하고자 하는 기술입니다. 3DTV 입체방송은 흑백TV에서 컬러TV로의 변화와 같이 영상 매체의 큰 변혁을 몰고 올 차세대 서비스로 주목 받고 있습니다. 또한 그 기반이 되는 3D 입체영상 기술은 TV방송뿐만 아니라, 게임, 교육, 의료, 산업 설계, 탐사 및 국방 분야에 이르기까지 매우 다양한 분야에 적용되어 기존과는 차별되는 성능과 경험을 제공하게 될 것이며, 잠재적인 산업 파급효과가 대단히 클 것으로 기대되고 있습니다. 이러한 3DTV 방송의 활성화를 위해서는 디스플레이, 콘텐츠 및 서비스 인프라를 포함하는 eco-system이 잘 조정되어야 하며, 특히 시각 피로 및 시각안전성과 같은 인간공학적인 측면에서 연구 및 관련 표준화가 뒷받침되어야 합니다. 3DTV 기술은 초기의 안경 착용이 필요한 스테레오 3DTV로부터 지속적으로 발전하여 장기적으로 안경 착용이 필요 없는 다시점 또는 홀로그래픽 3DTV가 실현될 것이며, 이에 대비한 기초기반 연구도 꾸준히 병행되어야 할 것입니다.

사람 간 의사소통에서 표정, 몸짓과 같은 비언어적 시각 요소들은 감정 표현의 중요한 요소이나, 시각장애인들은 이러한 감정 정보들을 받아들이는데 제한적이다. 본 논문은 시각장애인에게 이러한 비언어적 시각 요소 기반의 감정 정보를 인식하여 온각으로 전달하기 위한 방법론을 제안한다. 상대방의 표정은 안경 착용형 카메라로 인식되어 감정으로 분류된다. 인식된 표정이 웃는 얼굴과 같이 호감인 경우, 이 상태는 온각으로 변환되어 안경에 착용된 온도전달 장치에서 시각장애인에게 호감을 전달한다. 이러한 온각기반 감정전달 장치는 시각장애인의 의사소통 향상을 위한 장치의 개발에 응용될 수 있다.

Purpose: The purpose of this study is to investigate the differences of dynamic visual acuity to color of optical lens. Methods: we measured dynamic visual acuity using 5 colored lenses (transparent, yellow, blue, green, brown) for 30 university students. Results: Dynamic visual acuity were highest on yellow colored lens and lowest on brown colored lens, for both of naked eyes and contact lens wearers. Conclusions: It can be concluded that optical lens color can influence on dynamic visual acuity. Selection of colour lense can enhance or decrease of dynamic visual acuity. Therefore, a selection of colour lense should be carefully decided especially for athletes who needs a good dynamic visual acuity.

This study was researched the state and problem of the soft contact Lens wear by the history and inverted microscopy. The results was as follows; 1. The first use of contact lens wear was the 15 years and the last use was the 26 years. The first age of most contact lens wear was the 19 years. 2. In the almost contact lens wearers, the first visual test was the optical shop. 3. At present, almost soft contact lens purchase the optical shop 4. At present, most contact lens wearer like a soft type. 5. At present, most soft contact lens were a domestic production, and some subjects were foreign country production, but some subjects were unknown. 6. After contact lens wear, most subjects don't known the corrected visual acuity, especially, almost people don't known the binocular visual acuity. 7. At present, on soft contact lens color, the teens like the non-color contact lens, twenties like the color contact lens, but thirties was not known. 8. On the advantage of soft contact lens knowledge, most teens and twenties were only one, thirties was unknown. 9. On the disadvantage of soft contact lens knowledge, most teens and thirties were only one, twenties were two. 10. On the side effect of soft contact lens wearer, teens was one, and twenties and thirties don't known. 11. On the main symptoms of soft contact lens wearer, total kinds were seven, On these kinds, most subjects were not symptoms, the next order was unknown on the symptom. But, On the symptoms, the main symptoms was the pain and dry eye. 12. At present, the research on the surface morphology of soft contact lens by inverted microscope, the lens repture, lens folding, foreign body immersion and etc were present. Above the study, most contact lens was soft lens, and the purchase was the optical shop, on the other hand, the knowledge of soft contact lens and visual acuity was few. As a results, On the practical problems of soft contact lens wear, the optician have to the soft contact lens treatment and aftercare by law and educational supporting.

This study were to investigate the scratches and replacement cycles of eyeglasses according to personal characteristics in daily life. The subjects were 58 people who voluntarily participated in this study. The replacement cycle of eyeglasses according to the contact of eyelashes with eyeglasses, type and the number of eyeglasses wiped on a day were analyzed. The statistical analysis were performed by X² test and Fisher's exact test. The average replacement cycle of the eyeglasses were longer females than males. The eyeglasses replacement cycle were significantly shorter when the eyelashes contacted the eyeglasses and when the eyeglasses were wiped using a tissue or clothes other than the eyeglasses towel. The coating film of the eyeglasses may be damaged by the convergence effect such as eyelashes or minor carelessness in daily life, and this study will continue to follow up on this result.

The Hydroxyethyl methacrylate(HEMA) was developped in 1960's and later the use of contact lenses increased. At present more and more people use RGP contact lenses. Due to the wide range of optical corrections available and due to their high oxygen transmission Japanese and Korean people like them. Nevertheless one of nine CL users(beginners) stopped wearing the CL within the first year. We conducted a survey to evaluate the level of patient compliance in lens care and maintenance and to assess practitioner knowledge of contact lens information. Generally 6% of contact lens wearers drop out per year. The aim of this research was to find out what opticians can do to reduce the drop-out rate by getting information on handling, on general data of the patient and on optical prescription. Lens wearer were asked to complete a 10 question survey that focused on lens care-wear modality, lens replacement, storage, symptoms and case disinfection. There were total 180 participants in the study. Most of contact lens wearers have an inadequate understanding of contact lens care system. Therefore, it is important that contact lens specialists place more emphasis on practitioner education about general contact lens fields and reinforce patient education during the dispensing visit.

This study researched how the refraction error and illumination influence to contrast sensitivity when we wear the circle contact lenses. The study population comprised 16 students and adults(5 of Male, 11 of Female). The study population comprised 16 students and adults(5 of Male, 11 of Female), We measured the contrast sensitivity on uncorrected vision, according to color of circle contact and change the illumination of laboratory. The contrast sensitivity by illumination decreased than unaided vision when they wore the color contact lenses and more increased mesopic than photopic. Compared between black and brown lenses, brown was higher the contrast sensitivity than black. Also emmetropia had significantly differences when we compared the contrast sensitivity of subjects who had emmetropia, myopia and myopia astigmatism whether refractive error has or not. Therefore, it is important to provide sufficient understanding and recognition of color contact lenses.
