Protein deposits are a common form of soft contact lens deposits. They result from the interaction of your contact lens with proteins found in your natural tears. Two different types of proteins form on your soft contact lens:
A transparent, natural protein that is always present in your tears. It has no significant impact on your vision, your health or your lens comfort, and is easily removed.
This opaque deposit binds strongly to the lens surface and leads to decreased lens comfort and cloudy vision.
Removing protein from soft contact lenses
Until the introduction of multi-purpose solutions, protein deposits needed to be removed, at least weekly, using separate enzymatic cleaners.
This was time-consuming and inconvenient. It required tablets, and vials, and sometimes even a separate solution to dissolve the enzyme tablets.
The more convenient multi-purpose solutions available in the market usually contain a daily protein remover, which effectively removes both native and denatured protein during the daily cleaning step.
You only need one bottle to clean, rinse, disinfect and remove protein every day, without the need for a separate enzyme cleaner.
