How to Get Rid of Spots on Contact Lenses
Understanding Contact Lens Deposits
Spots, film, and cloudy patches on contact lenses are among the most common complaints from lens wearers. According to the CDC, approximately 40-90% of contact lens wearers do not properly follow lens care instructions, which can lead to protein and lipid deposits forming spots on lenses (CDC, 2024). These deposits can blur your vision, reduce comfort, and raise the risk of eye irritation or infection if left unaddressed. At Greenwich Ophthalmology Associates, our specialty contact lens fitters serving the greater NY/CT region help patients identify the cause of lens deposits and find the right cleaning routine or lens type to restore clear, comfortable vision.
Your tear film naturally contains proteins such as lysozyme and albumin that help protect and lubricate the eye. When these proteins adhere to the contact lens surface, they can denature, or change shape, and form a whitish haze or small raised bumps. Soft contact lenses made of older hydrogel materials tend to attract more protein deposits than silicone hydrogel or rigid gas permeable lenses.
Oils secreted by the meibomian glands along your eyelid margins are a normal part of your tear film. However, these lipids can coat the contact lens and create a filmy, smudged appearance that is difficult to blink away. Silicone hydrogel lenses, while excellent at transmitting oxygen, are more prone to lipid buildup than traditional hydrogel materials.
Small white or crystalline spots on a contact lens are often caused by calcium or other mineral deposits from the tear film. These tend to form gradually over weeks and are more common in patients with certain tear compositions or those who wear lenses well beyond their recommended replacement schedule.
Who Is Most Susceptible to Contact Lens Deposits
Patients whose tears contain higher concentrations of protein or lipid are more likely to develop deposits quickly. Those with dry eye disease may also experience faster buildup because reduced tear flow means less natural rinsing of the lens surface throughout the day.
The type of contact lens you wear plays a significant role. Monthly and bi-weekly lenses accumulate more deposits over their wearing cycle compared to daily disposable lenses, which are discarded after each use. Patients who wear multifocal or reading contact lenses are subject to the same deposit risks and benefit equally from following their prescribed replacement schedule.
Overwearing lenses beyond their recommended schedule, sleeping in lenses not approved for overnight use, and inconsistent cleaning routines all accelerate deposit formation. Proper contact lens care and hygiene is especially important for preventing deposits and maintaining healthy eyes.
Dusty work environments, exposure to smoke, high pollen counts during allergy season, and prolonged screen time with reduced blinking can all contribute to faster deposit accumulation on your lenses.
How Spots Affect Your Vision and Eye Health
A thin layer of protein or lipid across the lens surface scatters light as it enters the eye, producing a hazy or foggy quality to your vision. Many patients describe this as feeling like they are looking through a dirty window. Blinking or using rewetting drops may temporarily improve clarity, but the underlying deposits remain until the lens is properly cleaned or replaced.
Raised protein bumps or rough calcium deposits can create friction between the lens and the delicate tissue of your inner eyelid. This friction may cause redness, a gritty sensation, and shorter comfortable wearing times. In some cases, persistent deposits can contribute to giant papillary conjunctivitis (GPC), an inflammatory reaction on the inner eyelid surface.
Deposits provide a surface for bacteria and other microorganisms to attach and multiply, forming what is known as a biofilm. A contaminated lens held against the cornea for hours each day raises the risk of microbial keratitis, a serious corneal infection that can threaten your sight.
How to Remove Spots and Deposits from Contact Lenses
Even if your multipurpose solution is labeled 'no rub,' gently rubbing the lens in the palm of your hand with a few drops of solution for about 20 seconds per side is the single most effective step for removing deposits. Follow the rubbing with a thorough rinse of fresh solution before placing the lens in a clean case filled with new solution.
Hydrogen peroxide-based systems use a 3% peroxide solution with a special neutralizing case to provide a deeper clean than most multipurpose solutions. The peroxide breaks down protein and lipid deposits during the soaking period and is then converted into gentle saline before the lens is worn again. Because the end result is preservative-free, these systems are a good option for patients with sensitive eyes.
For lenses with heavy protein deposits, enzymatic cleaning tablets can supplement your daily cleaning routine. These products contain enzymes that break down protein bonds on the lens surface. They are typically used once a week and work well for monthly or bi-weekly replacement lenses.
If deposits persist despite proper cleaning, the lens may need to be replaced ahead of schedule. Heavily coated lenses cannot always be restored to a safe, comfortable state. Patients with chronic deposit issues or complex prescriptions may benefit from specialty contact lenses designed for hard-to-fit eyes, which can offer materials better matched to their tear chemistry.
Frequently Asked Questions
You cannot eliminate deposits completely because they originate from your natural tear film, but you can significantly reduce them. Washing your hands thoroughly before handling lenses, applying eye makeup after lens insertion, and using a rub-and-rinse technique each day all help keep deposits to a minimum.
Yes. Because daily disposable lenses are discarded after a single use, deposits never have time to build up meaningfully. This makes dailies an excellent choice for patients who are prone to protein or lipid deposits, have allergies, or prefer the convenience of a fresh lens each morning.
Always empty old solution from your lens case before refilling with fresh solution. Never top off or reuse solution from the previous night. Replace your lens case at least every three months, or each time you open a new bottle of solution. Allow the empty case to air dry face down on a clean tissue between uses.
Deposits themselves do not directly cause infection, but they create a surface where bacteria and fungi can thrive. A heavily deposited lens combined with poor hygiene significantly raises your risk of a corneal infection. If you notice persistent redness, pain, or sensitivity to light while wearing contacts, remove them immediately.
If you notice hazy vision, discomfort, or visible spots that do not improve after a thorough cleaning session, replace the lens rather than continuing to wear it. Monthly lens wearers should never exceed 30 days of use, and bi-weekly lenses should be discarded after 14 days regardless of appearance.
Schedule a contact lens appointment if deposits return quickly despite consistent cleaning habits, if you experience frequent discomfort or redness, or if your vision stays blurry even with fresh lenses. Patients with recurring deposit issues often benefit from exploring materials and designs better matched to their individual tear composition.
