Best Hygiene Practices with Scleral Lens Wear: Step-by-Step Protocols That Actually Work
Proper hygiene is the single most important factor in safe scleral lens wear. Following a consistent, evidence-based routine dramatically reduces your risk of serious eye infections, including corneal ulcers and sight-threatening conditions.
Key Takeaways
Always wash hands with mild, fragrance-free soap before handling scleral lenses.
Use a hydrogen peroxide-based solution for at least 6 hours to fully disinfect lenses.
Never rinse lenses or fill the bowl with tap water, as it can harbor Acanthamoeba.
Replace your lens case every 1-3 months and clean it daily to reduce contamination risk.
Protein and lipid deposits build up faster on scleral lenses due to the moisture chamber design — a daily surfactant cleaner is essential.
Schedule regular professional check-ins to catch fit or hygiene issues early.
Why Hand Hygiene Is the Starting Point for Every Scleral Lens Session
Before you touch your lenses, your hands must be completely clean. Wash with a mild, fragrance-free, lotion-free soap for at least 20 seconds, then rinse thoroughly and dry with a lint-free towel. Residue from moisturizers, hairspray, sunscreen, or scented soaps can transfer onto the lens surface and directly into the fluid reservoir that sits against your cornea.
This matters more with scleral lenses than with soft lenses because the bowl of saline solution that fills the lens creates direct, prolonged contact with the eye's surface. Any contamination you introduce during handling does not simply evaporate; it sits on your cornea for hours. According to research reviewed by the American Academy of Ophthalmology, approximately 99% of contact lens wearers report at least one hygiene risk behavior, making this the most common entry point for infection that you can learn more about when you visit the home page.
Daily Cleaning and Disinfection: The Hydrogen Peroxide Method
The most clinically supported approach to scleral lens disinfection uses a hydrogen peroxide-based solution, and it requires a minimum soak time of 6 hours. This is not a shortcut-friendly process. The peroxide must fully neutralize before the lens touches your eye. Skipping or shortening the neutralization cycle causes chemical burns to the cornea.
A complete daily care regimen for scleral lens wearers typically includes three steps:
Daily surfactant cleaner: Rub each lens for 1-2 minutes with a dedicated cleaning solution to physically remove protein, lipid, and mucin deposits. Clinical data shows that 62% of scleral lens patients use a separate daily surfactant cleaner, and those who skip it tend to accumulate more deposits.
Hydrogen peroxide disinfection: Submerge the lens in a peroxide system (such as Clear Care) for at least 6 hours, allowing full antimicrobial activity against bacteria, fungi, and protozoa.
Preservative-free saline rinse: Before insertion, rinse lenses thoroughly with a sterile, preservative-free saline or dedicated filling solution. Never use multipurpose soft lens solution, tap water, or distilled water as a substitute.
For patients managing conditions like keratoconus or severe dry eye, theNIH National Eye Institute provides helpful background on why specialty lens hygiene carries elevated importance when discussed with specialists like those featured on themeet the doctor page.
Solution Management: What You Use and When You Use It
Every day means fresh solution, no exceptions. Topping off existing solution in your case dilutes the disinfectant concentration and significantly reduces its effectiveness. Empty your case completely, rinse it with fresh solution (not water), and let it air dry face-down on a clean tissue.
The danger of tap water cannot be overstated. Acanthamoeba, a microscopic organism found in municipal water supplies, swimming pools, and even well water, can adhere to contact lenses and cause Acanthamoeba keratitis, a painful and difficult-to-treat infection. The CDC's contact lens health resources outline this risk in detail and confirm that tap water exposure is one of the leading preventable causes of lens-related eye infections that you can discuss further via the contact page.
Single-use vials of non preserved saline are the gold standard for filling the scleral lens bowl before insertion. Preserved saline can cause ocular surface irritation with repeated daily exposure.
Lens Case Care and Replacement Timeline
Most lens wearers overlook the case itself. Research indicates that up to 81% of lens cases show contamination, with cases older than 9 months carrying the highest contamination rates. Your recommended routine:
Rinse the case with fresh disinfecting solution after each use (never tap water)
Rub the inside of the case with a clean finger to remove biofilm
Air dry face-down on a lint-free surface with the caps off
Replace the case every 1-3 months, or immediately if you notice discoloration, deposits, or visible damage
Protein and Deposit Management for Scleral Lens Wearers
This is where scleral lenses differ from standard soft or rigid gas permeable (RGP) lenses in an important way. The moisture chamber design means that tears, mucin, and proteins are constantly in contact with the inner bowl of the lens. Lipid and protein deposits accumulate faster as a result, affecting optical clarity and comfort.
Weekly enzyme treatments or more frequent surfactant cleaning cycles are often recommended for heavy depositors. If you notice fogging or reduced vision quality midday, deposits may be the cause. This is a conversation worth having with your specialist, and you can explore theservices page at Texas Contact Lens Institute to review the specialty fitting options and lens care guidance available.
Insertion, Removal, and the Tools That Help
Scleral lenses require a plunger-style insertion tool and a DMV scleral vial or similar filling device. Keeping these tools clean is part of your hygiene protocol. Rinse your plunger with fresh saline before and after each use, and replace it every 3-6 months.
Avoid inserting or removing lenses over a hard surface. A folded clean towel placed in your sink creates a safer landing zone if the lens is accidentally dropped. Do not insert lenses in the shower or near running water.
You should also remove lenses before swimming in any body of water, including pools, hot tubs, lakes, and oceans. Waterborne pathogens and chlorine residue both pose risks to lens integrity and eye safety.
Recognizing Contamination and Knowing When to Seek Help
Infection warning signs include increased redness, light sensitivity, unusual discharge, blurred vision, or significant pain. If any of these appear, remove your lenses immediately and contact your eye care provider without delay. Do not attempt to self-diagnose.
The Mayo Clinic's guide on contact lens-related eye infections outlines the full symptom picture and reinforces when professional evaluation is urgent and should be discussed in detail through the blog.

Things to Know
Smoking is a documented risk factor for contact lens-related infections — quitting reduces this risk meaningfully.
Travel hygiene requires extra planning: bring single-use saline vials, a clean spare case, and avoid filling lenses with hotel tap water.
Preservative-free drops, not regular artificial tears, should be used while wearing scleral lenses to avoid compatibility issues.
If you wear scleral lenses due to a referral from another provider, Texas Contact Lens Institute accepts referrals and has a streamlined intake process.
Lens cases 9 months or older carry the highest contamination rates, making timely replacement non-negotiable.
Frequently Asked Questions
Q: Can I rinse my scleral lenses with tap water in an emergency?
No — tap water should never contact scleral lenses under any circumstances.
Tap water contains Acanthamoeba and other pathogens that can adhere to the lens and cause severe, vision-threatening infections. Carry a spare vial of preservative-free saline when traveling as your backup option.
Q: How often should I replace my scleral lens case?
Replace your lens case every 1 to 3 months, or sooner if it shows any visible contamination.
Lens cases are among the most overlooked hygiene factors. Biofilm builds up inside the case walls even with daily rinsing, and older cases have measurably higher contamination rates.
Q: Why do my scleral lenses fog up during the day?
Midday fogging is most commonly caused by lipid or mucin deposits entering the moisture chamber.
This can result from incomplete daily cleaning, a poorly fitting lens, or underlying dry eye. Discuss the issue with your specialist, as a fitting adjustment or cleaning protocol change often resolves it.
Q: Is hydrogen peroxide disinfection really necessary, or can I use multipurpose solution?
Hydrogen peroxide systems provide deeper disinfection and are strongly preferred for scleral lenses.
Multipurpose solutions are formulated for soft lenses and may not offer adequate antimicrobial activity for rigid scleral materials. They can also leave preservative residue that irritates the eye through the prolonged scleral lens moisture chamber.
Q: How do I know if my scleral lens hygiene routine is working?
Comfortable, clear vision with no redness, discharge, or sensitivity suggests your routine is effective.
Regular check-in appointments are the most reliable confirmation. Your provider can inspect lens surfaces for deposit buildup and assess the ocular surface for early signs of irritation before symptoms escalate.
