One way to get rid of the lenses is to use a protein cleaner. Most of those cleaners should be used once a week and are available as drops or as tabs working in a solution to clean the protein deposits on your contact lenses. With hard RGP lenses, you could switch to an abrasive cleaner.
What causes protein build up on contact lenses?
In addition to deactivation, the unfolding exposes previously hidden portions of the protein, causing the denatured protein to bind or attach to other substances. Within the tear film, as lysozyme denatures, it can build up on the surface of contact lenses, forming what we all refer to as protein deposits.1 may 2005

How do you remove protein deposits from soft contacts?
It is concluded that hydrogen peroxide/catalytic disc-based soft contact lens disinfection can remove up to 40% of the protein deposited on soft contact lenses.
What causes calcium buildup on contacts?
Lens calculi are composed of calcium, lipid and mucoprotein inherent in the tear film (Figure 2). Their formation is attributed to depletion of the aqueous tear layer that results in a hydrophobic zone that, in turn, promotes deposition. If significant in number and size, they can degrade comfort and vision.15 may 2020
What is protein on contact lenses?
Lysozyme is the major protein deposited on contact lenses and makes up 40 per cent of total tear proteins. It has a small molecular size, and is positively charged, so readily deposits on negatively charged substrates with a high water content.
What is an enzyme cleaner for contacts?
Enzymatic cleane is for removing protein from your contact lenses, usually on a weekly basis. You use the tablets with saline solution or disinfecting solution (multipurpose or hydrogen peroxide), as directed. Before using enzymatic cleaner, clean and rinse your contacts using other products.
