Abstract

Purpose : To investigate a disposal method of disposing contact lenses and the recognition of environmental pollution by micro plastics which may be caused by the wrong disposal method of domestic contact lens wearers. Methods : Two hundred sixty one adults(124 males, 137 females, mean age $21.48{\pm}3.14years$) were participated in this study. They were given the questionnaire survey on contact lenses purchasing place, type of contact lenses, duration of wearing contact lenses, the disposal method of disposing contact lenses and the recognition of the occurrence of environmental pollution. Results : It appeared that eyeglass shop(50.0%) and contact lens shop(48.3%) were the main purchasing places, and the most common type of contact lenses were disposable lenses(38.5%) and daily wearing lenses(52.5%). On the duration of wearing contact lenses they answered more than 5 years(29.3%), less than 1 year (26.0%), less than 1 year to less than 3 years (26.0%), and on wearing a contact lens during a week they did 1-2 days (32.0%), 1 week (28.0%), 5-6 days (22.4%) and 3-4 days (17.6%). It was shown "no(78.3%)" and "yes(21.7%)" to the questionnaire of whether they received information or education about a disposal method at the place where the contact lens was purchased, and "no(87.5%)" and "yes(12.5%)" to the questionnaire of whether they received information or education from schools, public institutions or public media such as the internet. As for the disposal methods, landfill waste(45.6%), recycled garbage(29.6%), and drainage(16.8%) from the sink or toilet responded in order. Although men were more educated and informed about disposal than women (t=3.63189, p<0.00001), women were more aware of environmental pollution(t=2.44269, p=0.01605). Conclusion : In order to reduce the environmental pollution issue caused by the contact lens which does not decompose at the sewage treatment facility and become micro plastics, it is urgent to provide information about correct disposal methods after using contact lenses and to educate contact lens wearers.

목적 : 국내 콘택트렌즈 착용자들의 렌즈 사용 후 폐기처분 방법, 잘못된 폐기방법으로 발생될 수 있는 미세플라스틱에 의한 환경오염에 대한 인식을 알아보고자 하였다. 방법 : 성인 261명(남자 124명, 여자 137명, 평균 나이 $21.48{\pm}3.14$세)을 대상으로 콘택트렌즈 주 구매처, 착용 콘택트렌즈 종류, 콘택트렌즈 착용 기간, 콘택트렌즈 폐기방법에 대한 정보나 교육을 받은 적이 있는지 여부, 콘택트렌즈 사용 후 폐기처분 방법, 환경오염 발생에 대한 인식에 대한 온라인 설문조사를 실시하였다. 결과 : 콘택트렌즈 주 구매처는 안경원(50.0%), 렌즈샵(48.3%) 순으로 나타났으며, 콘택트렌즈 종류로는 매일착용 렌즈 (52.5%), 일회용 렌즈(38.5%)를 가장 많이 착용하고 있었다. 콘택트렌즈를 착용해 온 기간은 5년 이상(29.3%), 1년 미만(26.0%), 1년 이상~3년 미만(26.0%) 순으로 나타났으며, 1주일 중 콘택트렌즈를 착용하는 기간은 1~2일 착용(32.0%)이 제일 많았고, 1주일 내내(28.0%), 5-6일 착용(22.4%), 3-4일(17.6%) 순으로 응답하였다. 콘택트렌즈 구매처에서 폐기처분에 대한 교육이나 정보를 접했는지 여부는 "아니다(78.3%)", "그렇다(21.7%)"로 나타났으며, 평소 학교나 공공기관, 인터넷 등 대중매체에서 콘택트렌즈 폐기처분에 대한 교육이나 정보를 접했는지 여부를 묻는 설문에는 교육받은 적 "없다(87.5%)", "있다(12.5%)"로 나타났다. 폐기처분 방법으로는 매립용 쓰레기(45.6%), 재활용 쓰레기(29.6%), 싱크대나 화장실을 통한 배수구(16.8%) 순으로 응답하였다. 남성이 여성보다 폐기처분에 대한 교육이나 정보를 더 많이 접했지만(t=3.63189, p<0.00001), 여성이 환경오염에 대한 인식이 더 높은 것으로 나타났다(t=2.44269, p=0.01605). 결론 : 하수처리 시설에서 분해되지 않고 미세플라스틱으로 변하는 콘택트렌즈로 인한 환경오염 문제를 줄이기 위해 콘택트렌즈 사용 후 올바른 폐기방법에 대한 정보를 제공하고 이에 대한 교육이 시급한 것으로 생각된다.
