In this study, we presented a research about the development of the phoropter simulation program for education using the 3-D virtual reality in order to study the ophthalmic optics rather efficiently. Especially, by putting the facility such as the refractive error analysis of the eyeball in the cyber tutor inside, we have made the learner to learn and confirm the present situation of refractive correction through refractive power of principal meridians. By organizing the system which induces the active involvement of the learner and showing the result of the execution to the learner intuitively, the implementation of the more efficient education-environment can be possible. Consequently, it is expected that this program will be greatly helpful for the optician training as well as the ophthalmic optics education. As a next phase of study, we will develope the development technique of this simulator more and extend the cyber tutor contents more and make the web service version of this program to be provided through the internet network in order to inspire the learning desire of the learner more and more.

Purpose: Concerns had been voiced about an oversupply of optometrists in Korea. So, this study aimed to forecast the supply and demand for opticians for policy implications. Methods: Baseline Projection model combined with demographic method was adopted as the supply forecasting method and so was a ratio method using the number of physician and population using weight of healthcare utilization. Results: Under the 'physician to optician ratio', there would be a surplus of 83~700 opticians in 2010 and an undersupply of 15 to surplus of 6,118 opticians in 2025. Under the 'population to optician ratio', there would be a surplus of 1,055 opticians in 2010 and surplus of 9,376 opticians in 2025. Conclusions: We concluded that there would be oversupply for opticians until 2025, although the shortage and surplus of opticians might depend on the ratio's criteria. Hence, policies would need to be developed that could solve the imbalance in requirements and supply for opticians.

To investigate the wear status of contact lenses by analyzing care of contact lenses container and actual condition of people wearing contact lenses and in Gyeonggido. The results were based on a questionnaire survey of 200 people who are the students of the middle school, the high school and the college among the clients of opticians to purchase contact lenses for six months from January 2013 to July 2013. According to the poll, the highest number of those polled, 139 (55.16%) people, said they were wearing cosmetic color contact lenses. Female respondents and male respondents were in the proportion of 177 (88.5%) to 23 (11.5%), respectively. 37 people (18.5%) who responded said "yes" to the question of them sharing contact lenses and glasses. 103 people (51.5%) answered "no" to the question of regularly replacing their lens containers. 148 people (74%) answered "yes" to the question of having glasses in order to investigate contact lens wearers user rate of glasses. The highest number of respondents, 127 people (63.5%), said "middle school" was the first time that they wore contacts. Meanwhile, 65 people (43.92%) said they initiated wearing glasses at 4th-6th grades. It is considered that it is necessary using proper contact lenses suitable for the clients' eye health in order of vision correction, rather than for cosmetic purposes. The role of the optician is considered to be very important for the proper management of the appropriate contact lens hygiene and regular optical check-ups of the contact lens wearers.

Purpose. The purpose of this study was to investigate career awareness of the students majoring in optometry in Gyeongnam area so that it could be used as a database to educate them on their career. Methods. The graduates of the Department of Optometry in 6 universities of Gyeongnam area were surveyed through a questionnaire. Results. Most of their motive for entering Department of Optometry was for 'finding a job(38%), while at the time of entrance, most of them (55%) thought 'optician' as their job after graduation. Now most of them are the expectant graduate and they still think 'optician' as their job(54%). The biggest reason why they think of this career was 'aptitude(34%),' and most of them wanted their first monthly wage as less than '1.5 million won (46%).' For the desired work time, most of them said 'less than 10 hours a day (73%),' and they have been figured out to want '2 days off a week and monthly paid holiday (35%).' For the questions asking any improvements that are needed for department of Optometry, they (32%) answered 'equipments that are old or in short.' For the question asking if they are willing to choose optical task even if they entered a company that is irrelevant with it, most of them (37%) said they will if the conditions work, and the other 37% said they didn't know. Conclusions. The cooperation among universities and the field and their interest are required so that the students of the Department of Optometry would be able to work with pride as a professional to improve social welfare.

We obtained the UV cut-off effect of tinted CR-39 Ophthalmic lens with the respect of concentration of green, brown, blue color. First, we analyzed the UV spectrum of tinted CR-39 lens measured by Spectrophotometer and then compared the UV data by Spectrophotometer with UV data by UV tester used in an optician shop. The result obtained show that the UV cut-off effect is increased with color concentration of tinted CR-39 lens, and the transmittance of 0%~5% at 400nm by Spectrophotometer is correspondence with transmittance of 0% by UV tester.

The physiology and morphology of cornea has effected on the ocular refractive status. Therefore the measurement of the anterior corneal surface by keratometer is used the treatment of the spectacles and contact lens by optician, optometrist, and ophthalmologist. Furthermore, currently the most corneal topographic mapping system have used the clinical optical shop, eye research center, and eye hospital. Because this method have a very fine data comparative to the previous instrument. The authors have measurement the cornea of the man college students by the corneal topographic mapping method. Especially this data will applied the clinical practice for the contact lens fitting. Especially in Korea, many man college students use the contact lens for the visual acuity and a beauty. Therefore the contact lens wear have increase per every year.

The human eye and skin is exposed daily to solar energy. Expecially, the ultraviolet radiation (UVR) exposure has been damaged as an important causative factor in corneal disease. These damage of cornea was effected the retina. Therefore the eye function was effected very significant damage. As a results the protect of UVR in the eye is very important in ocular health. Therefore in living the intensive ultraviolet radiation environment by solar energy, human eye have protected the cornea and eyeball by the UV-blocking sunglass, eyeglass, goggles, and contact lens. Finally the specific UV-blocker lens devices available to the primary care for the subjects by optician. Of course, in the future these specific lenses have to development and study by fellowship.

When we wear contact lenses for correcting astigmatism, we often experience the axis-rotation of contact lenses that is happened in case we could not fit the axis of lens exactly or by the eyelid used to blink. In this case, because the exact correcting state becomes in the wrongly correcting state, the asthenopia is led, and the decline of eyesight can be led. For this reason, we need to know axis-rotating degrees of contact lenses. If a contact lens rotated, a residual astigmatism may be detected in the refraction examination after wearing. Using this, we developed a program that calculates the axis-rotating amount of contact lenses.

This study investigated the development of eyeglasses and design transition in materials and types through literature survey. The scope of this study on the basis of the 15th century, for this study survey reaches from the 15th century to modern. The result of this study were as follows. Real magnifying glasses was first mentioned by the Arab physicist al-Hazen who was famous of his treatise on optics. The oldest documents which explicitly refer to the art of making lenses for eyeglasses and magnifying glasses were the Venetian artisans of 1300. In the 15th century someone thought to remedy the unstability of glasses by securing the bridge on the forehead. But it was only in the 17th century that someone contrived to stabilize the frame by strapping it on the face by means of fine cords that reached behind the ears. Eventually in the early years of the 18th century the English optician Edward Scarlett invented the rigid earpieces which solved once and for all the problem of holding the eyeglasses firmly in place. In the 19th century, eyeglasses' fashion were monocle and pince-nez. In the 20th century, various lenses and frames were appeared. Therefore eyeglasses to correct defective sight, sun-glasses, as well as a most succesful item among modern fashion accessories.
