Protein build-up is the leading cause of shortened lens life and reduced comfort in monthly and bi-weekly contact wearers. The right cleaning system breaks down deposits rather than just rinsing the surface. Here are five products that address protein effectively.

Alcon Clear Care Plus — Best for Heavy Protein Depositors
Hydrogen peroxide cleaning systems consistently outperform multipurpose solutions on protein removal because peroxide is a stronger oxidizing agent that breaks down protein bonds at the molecular level. Clear Care Plus uses a 3% hydrogen peroxide solution that must be fully neutralized in the provided case over six hours. The platinum disc in the case catalyzes neutralization, and the resulting solution is gentle saline. The Plus version adds HydraGlyde for moisture. For monthly lens wearers who notice haze or discomfort within a few days of cleaning, this system is the most effective option available over the counter.

Opti-Free Puremoist — Best Daily MPS with Enzyme Action
Opti-Free Puremoist contains a low-level enzyme component that addresses mild daily protein deposits during the standard overnight soak. For wearers who do not have extreme protein deposition, this all-in-one approach means no separate enzyme step. The HydraGlyde Moisture Matrix coating it deposits on the lens is a bonus that also helps comfort. This is a good fit for wearers who want simplified care with reasonable protein management, and who are not heavy depositors requiring the full hydrogen peroxide treatment.

Lobob Optimum Extra Strength Cleaner — Best Manual Scrub Cleaner
Lobob Optimum is a daily cleaner designed to be rubbed onto the lens surface before rinsing and soaking in a separate disinfecting solution. The mechanical action of rubbing combined with the surfactant formula physically removes protein and lipid films that soaking alone leaves behind. This two-step approach (daily cleaner plus MPS or peroxide soak) is the most thorough routine available for heavy depositors. The Lobob formula is gentle enough for both soft and rigid gas-permeable lenses. It requires an extra minute in the nightly routine but delivers visibly cleaner lenses.

Bausch + Lomb renu Advanced — Best Budget Daily Cleaner
renu Advanced is a capable budget-tier multipurpose solution that includes a conditioning surfactant which provides mild protein removal during the soak cycle. It does not match the enzyme action of Opti-Free Puremoist or the oxidative cleaning of Clear Care, but for light depositors wearing monthly lenses it provides adequate daily maintenance. The solution is widely stocked and often available in large value sizes that reduce the per-use cost. A good option for wearers establishing a routine who want a reliable everyday solution without premium pricing.

Alcon Sauflon All-in-One Light — Best Single-Step for Light Depositors
All-in-One Light is designed for wearers with minimal deposit build-up who want the simplest possible care routine. The formulation focuses on disinfection and basic surface cleaning with a gentle preservative system. It is not the right choice for monthly lens wearers who experience significant protein haze, but for wearers of two-week lenses or those with naturally lower deposit levels it handles daily cleaning with minimum steps. The large bottle size delivers good value, and the formula is gentle enough for sensitive eyes.

How to Choose a Contact Lens Solution for Protein Build-Up
Identify how severe your protein build-up is. Light haziness at the end of a monthly cycle suggests a standard MPS with enzyme activity is sufficient. If your lenses become uncomfortable or visibly hazy within a week of cleaning, a hydrogen peroxide system like Clear Care is more appropriate.
The rub step matters significantly. Studies consistently show that rubbing lenses with solution before soaking removes more protein and microbes than no-rub soaking alone. Even solutions labeled “no rub” benefit from 10 to 15 seconds of manual friction.
If you switch to daily disposables, protein build-up becomes a non-issue since each lens starts fresh. For those committed to monthlies or bi-weeklies, pairing a daily MPS with a weekly hydrogen peroxide soak is the most effective long-term strategy.

Frequently asked questions
Why do proteins build up on contact lenses?+
Natural proteins found in tear film, particularly lysozyme, deposit on contact lens surfaces during wear. Monthly and bi-weekly lenses accumulate more protein than daily disposables because they are worn longer. Silicone hydrogel materials can attract more lipid deposits than older hydrogel lenses. Without adequate cleaning, these deposits cloud vision and reduce oxygen flow to the cornea over time.
How often should I use an enzyme cleaner for contact lenses?+
Traditional enzyme tablets are typically used once a week for monthly or bi-weekly lens wearers. Modern multipurpose solutions with built-in enzyme activity can handle mild deposits with daily use. If you are a heavy protein depositor (your lenses feel uncomfortable or appear hazy within a few days of cleaning), adding a dedicated weekly enzyme soak on top of daily MPS cleaning is the most effective approach.
