Abstract
Purpose
The purpose of this study was to investigate the difference in the staining degree according to the type of ingredients contained in liquid eyeliners and cleaning effect of contact lenses.
Methods
Three kinds of eyeliners containing red yellow, and black oxides of iron, and another three kinds of liquid eyeliner mixed with two or three iron oxides were diluted in saline. Then, their staining degree was observed by naked eyes and their transparency was measured, respectively, after 1 hr-immersion of somofilcon A, nesofilcon A, galyfilcon A, etafilcon A lenses in the diluted saline followed by cleaning.
Results
The etafilcon A and somofilcon A lenses showed the highest staining when immersed in the eyeliner solution containing black oxide of iron. The staining degree of nesofilcon A lenses was highest when deposited with the eyeliner containing yellow oxide of iron. Galyfilcon A lenses showed the highest degree of staining in the eyeliner solution containing red oxide of iron, and a mixture of red and yellow oxides of iron. In the case of the nesofilcon A lenses immersed in the eyeliner solution containing yellow oxide of iron, the most staining remained after cleaned with a multipurpose solution.
Conclusions
From this study, it is revealed that soft contact lenses are stained by liquid eyeliners, and the staining can not be returned to the baseline even when washed with multipurpose solution since irreversible staining may be induced depending on the ingredients contained in eyeliners. Therefore, it may be necessary to educate soft contact lens wearers about the cosmetics that cause staining in advance.
