1
Soak your contact lenses in an enzyme tablet solution, as listed by AllAboutVision.com. Since many manufacturers have eliminated this treatment in favor of the more convenient disinfectant solutions, you may have never used enzyme tablets. Follow directions included in the package, which usually involve dissolving the tablets in a specific lens solution in a lens case, and then soaking the lenses for a minimum of eight hours.

Use an electronic cleaning system, another device recommended by AllAboutVision. This type of system removes deposits through ultrasound waves or subsonic agitation, and then uses ultraviolet rays to destroy any microorganisms. If calcium deposits still remain, manually rub the lens with the solution that comes with the cleaning system.

Use thermal disinfection to remove deposits from your contact lenses, a method explained by ContactLensAnswers.com. Because this method can damage some types of soft contacts, be sure to ask your doctor first if you can clean your contacts this way. Like enzyme tablets, thermal disinfection is another method that has mostly been replaced with chemical disinfecting solutions, but some people still prefer it. If your eye doctor gives you the go-ahead, look for a new heat unit at online stores or ask your friends and family members if they have one you can use. Follow the directions that come with the unit.
