Abstract:
본발명은 카라기난을 이용한 고 습윤성 및 항균성 콘택트렌즈 제조방법에 관한 것으로, 용기에 기본시료를 혼합하여 균질화한 다음 캐스트 몰드(cast mold)에 주입하여 열중합하는 1단계; 중합체를 캐스트 몰드에서 꺼내어 초순수로 미반응된 물질을 제거하며 수화시키는 2단계; 상기 중합체를 카라기난이 포함된 IPN 용액에 침지시키는 3단계; 렌즈 표면에 붙은 미반응 물질을 증류수로 세척하여 콘택트렌즈를 제조하는 5단계;를 포함하는 것으로, 본 발명에 의해 제조된 콘택트렌즈은 하이드로겔 콘택트렌즈에 카라기난을 이용한 IPN으로 카라기난콘택트렌즈를 제조하여 고습윤성, 고산소투과성, 단백질부착저하, 그리고 고항균성을 가지는 현저한 효과가 있다.
Abstract:
The hanger for spectacles according to the present invention is a hanger for spectacles capable of hanging spectacles, in which a spectacles hanger part of high elastic flexible synthetic resin is integrally formed on the external side of an adsorption plate of high elastic flexible synthetic resin, hanging grooves formed from the upper part of the spectacles hanger part along both sides are formed on the surrounding surface of the spectacles hanger part, an adhesion strengthening groove connected to the inner side of the adsorption plate is formed within the spectacles hanger part, and a wall adhesion member having an insertion part inserted into the adhesion strengthening groove is attached to the wall with a double-sided tape or an adhesive. According to the present invention, spectacles are easily hung in a preset position in washing the face and sleep, and hygienically and conveniently hung as the bridge part of spectacles is able to be hung over the hanging groove of the spectacles hanging part by fixing the adsorption plate on a mirror in front of a basin or fixing the wall adhesion member to the wall with a double-sided tape. When the hanger for spectacles is attached to the mirror, the vacuum within the adsorption plate is increased due to the adhesion strengthening groove formed within the spectacles hanger part by pressing the hanger for spectacles, adhering the adsorption plate to the mirror and releasing the hanger for spectacles, and the hanger for spectacles is strongly fixed to a smooth surface such as a mirror.
Abstract:
A student training system and a training method by industry-university cooperation according to the present invention comprises an optician which collects customers through an internet network by building a website; an educational institution which cooperates with the optician and educates students who practices for an ocular function test to the customer collected by the optician; and a server which is connected to the optician and the educational institution by the internet network, stores the results of the ocular function test by the students and the results of the ocular function test by the optician, stores the client information, the ocular function training level information of the customer, and the information of the customer's glasses in the database. [Reference numerals] (AA) Perform ocular function test for the customers (subjects) collected by opticians in nearby optician training institutions or schools;(BB) Students of the institutions or schools practice an ocular function test for the customers (subjects) and store the results of the ocular function test;(CC) Opticians perform an ocular function test for the customers (subjects) and store the results of the ocular function test;(DD) Opticians perform ocular function and glasses training fitting for the customers (subjects) and store the information
