Protein deposits are a natural accumulation of tear film components, primarily proteins and lipids, that build up on the surface of contact lenses over time. When exposed to air and heat, these organic compounds dry, harden, and stick to the lens material, reducing comfort and clarity.
read more about protein deposits ...Protein deposits affect vision and comfort in several ways:
Yes, severe or persistent protein deposit buildup is a serious risk. Chronic protein deposits can trigger a condition called Giant Papillary Conjunctivitis (GPC), which is a severe allergic reaction where the inner eyelid develops large, inflamed bumps, forcing the patient to stop wearing contact lenses entirely until the inflammation is resolved.
No, you do not need a prescription to buy the products needed to clean and prevent deposits. However, your eye doctor will prescribe the correct type of contact lens solution (multipurpose, hydrogen peroxide, etc.) and replacement schedule that is best suited for your eyes and deposit tendency.
Management relies entirely on strict adherence to a cleaning routine and replacement schedule:
Are daily disposable lenses better for deposits?
Yes. Since you discard daily disposables before deposits have time to accumulate and solidify, they are the best solution for patients prone to heavy deposits or GPC.
Can I use water to clean the deposits off my lenses?
No. Tap water contains microorganisms that can cause severe eye infections, and water does not effectively remove protein deposits.
Are hard contact lenses affected by protein deposits?
Yes, rigid gas permeable (RGP) lenses can also accumulate deposits, but they generally require a different type of cleaning solution.
