육도진,Youk, Do-Jin 한국안광학회 2003 한국안광학회지 Vol.8 No.2

본 연구는 50세 이상 근용안경을 착용하는 사람 중 동공간 거리에 영향을 주는 요인인 안면, 안검 안와 및 안구 등에 질환이나 기형이 없는 총 검사 대상자 1071명(남자 432명, 여자 639명)을 성별, 연령별로 근용 동공간 거리 524명(남자 202명, 여자 322명), 근용도수 측정자 1071명 조사하였다. 성별 평균 근용도수를 비교 분석한 결과 남자는 평균 S+2.34Dptr, 여자는 S+2.23Dptr로 그 차는 남자가 0.11Dptr 정도 더 높게 측정되었지만 아주 미소한 차로 나타나 나이가 많아짐에 따라 조절력의 감소 변화는 남녀 모두 같은 것으로 조사되었다. 현재 판매되고 있는 상품화된 근용안경을 F.P.D별 5개 그룹으로 분류하여 각 그룹별 O.C의 평균값(1그룹 64.04mm, 2그룹 66.96mm, 3그룹 68.28mm, 4그룹 62.03mm, 5그룹 72.00mm, 5개 그룹 평균 66.66mm)과 검사 대상자 남녀별 근용 P.D의 평균값(남자 60.04mm, 여자 58.23mm)을 비교했을 때 상품화된 근용안경의 O.C가 모두 크게 조사되었으며, 근용 P.D는 남자가 여자보다 평균 l.81mm가 더 큰 것으로 조사되었다. 또한 상품화된 근용안경의 O.C의 평균값 66.66mm와 근용안경 착용자의 근용 P.D의 차로 인한 프리즘 발생량을 남녀별로 비교한 결과 남자는 최저 $0.23{\Delta}$에서 최고 $5.06{\Delta}$로 평균 $1.66{\Delta}$, 여자는 최저 평균 $0.46{\Delta}$에서 최고 $5.79{\Delta}$의 영향을 받게되는 것으로 조사되었다. 그리고 상품화된 근용안경을 공용으로 착용할 경우 남녀가 각각 받는 프리즘영향은 근용 P.D가 큰 남자보다 P.D가 작은 여자가 평균 0.45 프리즘 디옵터의 영향을 더 많이 받는 것으로 조사되었다. This study investigated that total 1071 reading glasses wearers (male 432, female 639) without any eye disease or deformation in eyelid, orbit, eyeball (over 50 years old), were tested. Reading pupillary distance of 524 (male 202, female 322) of 1071 were examined and reading glasses power was examined for all 1071 patients. As a result of average reading diopters analysis by sex. male had S+2.34Dptr, female had S+2.23Dptr in average and male had a little more average power than female by 0.11Dptr. However, the difference was not much enough and by aging accommodation reduction changes were applied to both male and female. After dividing ready-made reading glasses on sale in optical shops into 5 groups by F.P.D. the average D.B.O.C(distance between optical centers) of each 5 group was examined (1st group 64.04 mm, 2nd group 66.96 mm, 3rd group 68.28 mm, 1th group 62.03 mm, 5th group 72.00 mm : the average of all groups was 66.96 mm : each group included 3 random samples : 195 ready-made reading glasses were measured), and compared with the average reading P.D of males and females (male 60.04 mm, female 58.23 mm). The result showed D.B.O.C of ready-made reading glasses on sale was bigger than the average reading P.D of them. The result reviewed the average range for male was $0.23{\Delta}(minimum){\sim}5.06{\Delta}(maximum)$, and for female was $0.46{\Delta}{\sim}5.79{\Delta}$. In conclusion when wearing ready-made reading glasses, female got more effected by average $0.45{\Delta}$ because reading P.D of female was smaller than that of male.

We have compared with the transmittance of multi-coated CR-39(-0.25D) lenses in using the ocular shop from results of the spectrophotometer. The lenses prepared in A, C, and E company show low transmittance characteristics than ones a no-coated CR-39(-0.25D). This means a bad-quality coating effects. The lenses of B and D company show a good transparancy in visible spectral range.

Fresnel diffraction pattern was obtained using the He-Ne laser. The laser is regarded as the first truly coherent source was used for generating the diverse light. The iron of each thickness was equipped, the pattern was obtained and theoretical results using the Cornu line. The results was analysed.

The a-C:H films have been grown on the glass substrate by PECVD mathod, where plasma was generated with a 60Hz line power source. The carbonization is checked from peak intensities of D (sp³) and G(sp² peaks in Raman spectra. The hydronization and C-H bonding status in films can also be determined from FTIR results. Both the bonding strength of C-H and the ratio of sp³ to sp² in bonding are found to be slightly dependent of partial pressure of C₂H₂. Judging from above results, we can conclude that the best value for partial pressure of C₂H₂ in growing process of thick films is about 15%.

The spherical aberration was investigated with the different surface curvatures of meniscus lens. An incident ray with variable height from the optical axis shows different values of spherical aberration. Therefore, our results reveal the dependence of aberrations on surface curvatures and concluded that the aberration can be reduced by adjusting lens shapes.

Purpose: The purpose of this study is to evaluate the long-term stability of the improved symptoms and accommodative functions after completion of accommodative therapy. Methods: Seven children (mean age±SD: 12±1.41 years) who were successfully treated with a vision therapy program for either accommodative insufficiency or infacility were followed for 1 year. The visual symptoms of the subjects were measured by the College of Optometrists in Vision Development Quality of Life (COVD-QOL) checklist, and this was followed by measurement of the monocular and binocular accommodative facility with ±2.00 D flipper lens. Results: The mean visual symptoms at the 1 year follow-up examination (15.14±8.59) showed a small increase, but there was no significant difference (p=0.446) from post-therapy (11.86±7.22). There was small regression in the monocular (left eye, 13.86±3.93 cpm) and binocular (11.14±3.13 cpm) accommodative facility at the 1 year follow-up examination, but there were no significant different from the monocular (15.86±4.14 cpm, p=0.147) and binocular (13.21±3.76 cpm, p=0.066) accommodative facility measurements at post-therapy. Also, every subject met the normative values of 7 cpm for monocular accommodative facility and 5 cpm for binocular accommodative facility in the long-term. Conclusions: There was long-term maintenance of the improved visual symptoms and accommodative functions, and so it is clear that the positive therapeutic effects persist with accommodative therapy. 목적: 조절이상에 대한 치료가 완료된 어린이에 대해 장기간의 추적 관찰을 함으로써 치료직후에 향상된 눈증상 과 조절기능이 지속되는지의 여부를 확인하고자 하였다. 방법: 조절부족이나 조절난이가 있는 조절이상자에 대해 12 주 동안 비전세라피 프로그램을 실시한 결과 치료가 성공적으로 이루어진 남여 7명(평균 나이±SD, 12±1.41세)을 대상으로 1년이 경과한 후에 설문지를 사용하여 눈증상을 평가한 후 ±2.00 D 플리퍼 렌즈로 단안 및 양안의 조절 용이를 측정하였다. 결과: 치료 프로그램이 완료되고 1년이 경과한 다음 College of Optometrists in Vision Development Quality of Life(COVD-QOL)로 평가한 평균 눈증상은 15.14±8.53점으로 치료 직후의 11.86±7.60점 보다 작은 증가를 보였으나 유의하지 않았다(p=0.176). 그리고 단안(왼쪽 눈) 및 양안의 평균 조절용이 측정값도 각 각 13.86±3.93 cpm과 11.14±3.13 cpm으로 치료 직후의 15.86±4.14 cpm(p=0.147)과 13.21±3.76 cpm(p=0.066)보 다 작게 감소하였으나 유의하지는 않았으며, 대상자 모두에서 단안 및 양안 조절용이의 정상값인 7 cpm 이상과 5 cpm 이상을 각각 만족하였다. 결론: 장기간의 추적검사를 통해 치료 프로그램 직후에 향상된 눈증상과 조절기능이 여전히 지속되는 것을 볼 수 있었고, 따라서 조절이상에 대한 비전세라피의 치료효과가 장기적임을 확인하였다.

We study various effect on worning the spectacle frame before the eye. A small cylinderical bundle of rays, when falling obliquely upon a spherical surface, the greater the obliquity of the incident ray, the great will be the astigmatism that is increasied. Also when vertex length is not constant, field angle and diopter is changed.
