A testing method of assessing the protein-removing effect of the contact lenses' protein -removing care solution / 中国医疗器械杂志

<p><b>OBJECTIVE</b>Testing the protein-removing effect of the protein-removing care solution on the protein precipitation of the soft contact lenses.</p><p><b>METHOD</b>Soak the lenses into the artificial-tears to simulate the protein absorption, test the absorbency of cleaned protein at the wavelength of 280 nm by UV spectrophotometer, and compute the percentage of protein.</p><p><b>RESULT</b>Testing results of the percentage of the cleaned protein are repeatable.</p><p><b>CONCLUSION</b>This experimental method can be used to evaluate the cleaning effect of the protein- removing care solution, but still needs much improvements.</p>
