[A testing method of assessing the protein-removing effect of the contact lenses' protein -removing care solution].
OBJECTIVE
Testing the protein-removing effect of the protein-removing care solution on the protein precipitation of the soft contact lenses.


METHODS
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.


RESULTS
Testing results of the percentage of the cleaned protein are repeatable.


CONCLUSIONS
This experimental method can be used to evaluate the cleaning effect of the protein- removing care solution, but still needs much improvements.
