목적: 근거리 작업매체의 종류에 따른 사위 및 융합버전스 변화를 알아보고자 하였다. 방법: 교정시력이 1.0 이상인 20대 성인(남자 26명, 여자 4명, 평균나이 $24.8{\pm}1.8$세)을 대상으로 책과 스마트폰을 이용하여 동일한 조건에서 30분간 독서를 실시하도록 하였다. 근거리 작업 전과 책, 스마트폰을 이용한 VDT 작업 후의 수평, 수직사위도, 양성융합버전스 및 음성융합버전스를 측정하였다. 결과: 책을 이용한 독서 후에는 외사위안에서 통계적으로 유의하게 사위가 감소하여 내사위화 되는 것으로 나타났다. 스마트폰을 이용한 독서 후에는 외사위안, 정위안, 내사위안 모두에서 수평사위도가 통계적으로 유의하게 감소하는 것으로 나타났다. 수직사위도는 작업 매체와 관계없이 유의한 변화가 나타나지 않았다. 책을 이용한 근거리 작업 후에는 양성 및 음성융합버전스의 변화가 없었으나, 스마트폰을 이용한 VDT 작업 후에는 양성융합버전스가 통계적으로 유의하게 감소하였다. 결론: 스마트폰을 이용한 근거리 VDT 작업 후에 사위와 융합 기능의 변화가 관찰되어 스마트폰이 시기능의 변화를 유발하는 것으로 나타났다. 시기능을 유지시킬 수 있는 적절한 스마트폰 사용 기준이 제시되어야 할 필요성이 있음을 제안한다.

Purpose: The present study aimed to investigate the changes in heterophoria and fusional vergence by media type of near work. Methods: Adults in their twenties (26 males and 4 females, mean age $24.8{\pm}1.8years$) with a corrected visual acuity of 1.0 or better were asked to read a paper...
Purpose: The present study aimed to investigate the changes in heterophoria and fusional vergence by media type of near work. Methods: Adults in their twenties (26 males and 4 females, mean age $24.8{\pm}1.8years$) with a corrected visual acuity of 1.0 or better were asked to read a paper book and smartphone under the same condition for 30 minutes. The horizontal heterophria, vertical heterophoria, PFV(positive fusional vergence) and NFV(negative fusional vergence) were measured before and after near work with paper book and VDT work with smartphone. Results: The exophoric shift was shown by significant decrease of heterophoria in exophoric eyes after reading a paper book. Horizontal heterophoria was significantly decreased in all three type of exophoria, orthophoria and esophoria after reading with smartphone. Vertical heterophoria was not significantly changed regardless of the media type of near work. There was no significant change in the PFV and NFV after reading a paper book however, there was a significant decrease in the PFV after VDT work with smartphone. Conclusions: It was found that smartphone use induced the change of visual function since changes in heterophoria and vergence function was observed after VDT work using smartphone. Therefore, it is suggested that the appropriate guideline for smartphone use is necessary for maintaining the visual function.
