3N Contact Lenses Cleaner is a device utilized in effectively removing the protein deposition on contact lenses. It is independently developed by 3N Biological Technology Co., Ltd (3N Tech). Using the principle that proteins move in the electric field, 3N Contact Lenses Cleaner is able to adsorb proteins from the surface as well as the tiny holes of contact lenses, therefore, removes the protein deposition from the contact lenses effectively. In this study, we immersed contact lenses in artificial tears, and then proved 3N Contact Lenses Cleaner’s deproteinization effect with a qualitative detection using Coomassie Brilliant Blue G-250’s feature of indicating proteins. Meanwhile, we determined the device’s protein elution effect with Bradford method. The result indicates that 3N Contact Lenses Cleaner can distinctively remove the protein deposition from contact lenses.
