Proper contact lens cleaning requires rubbing the lens with fresh solution for 20 seconds per side, then rinsing and storing in a clean case.
Many contact lens wearers skip the rubbing step because their solution says “no‑rub,” but that shortcut raises the risk of infection. The correct method—rub, rinse, and store—takes about 90 seconds and is the only way to keep lenses comfortable and your eyes healthy.
The Official Rub‑and‑Rinse Method
The American Academy of Ophthalmology (AAO) and the American Optometric Association (AOA) both require the rub‑and‑rinse method for all lens types, even when the solution is labeled “no‑rub.” Follow these steps every time you remove your lenses.
| Step | Action | Duration / Specification |
|---|---|---|
| 1. Hand Prep | Wash hands with mild, fragrance‑free soap and warm water. | 20–60 seconds; dry with a lint‑free towel. |
| 2. Removal | Remove one lens and place it in your palm (bowl side up). | Same eye first each time to avoid mixing. |
| 3. Application | Apply fresh multipurpose solution to the lens. | Use enough drops to fully cover the lens. |
| 4. Rubbing | Gently rub the lens for 20 seconds on each side. | Use a circular motion with your finger pad. |
| 5. Rinsing | Rinse each side with a steady stream of fresh solution. | 5–10 seconds per side; do not just use a few drops. |
| 6. Storage | Place the lens in a clean case and fill the well with fresh solution. | Never top off old solution; always discard it first. |
| 7. Soaking | Let the lens soak to disinfect. | Minimum 4–8 hours (typically overnight). |
If you use a hydrogen peroxide system, soak the lenses for at least six hours and ensure the solution is neutralized before insertion—inserting unneutralized peroxide causes stinging. The AAO’s detailed lens care guidelines cover both multipurpose and peroxide systems.
Common Mistakes That Lead to Infections
Three errors cause most contact‑lens‑related eye infections: water exposure, topping off solution, and neglecting case hygiene. Avoid them to keep your eyes safe.
- Never use water. Tap, bottled, distilled, or lake water all contain microorganisms that can cause serious infections like Acanthamoeba keratitis. Rinse and store lenses only in sterile solution.
- No saliva or “top‑offs.” Wetting lenses with your mouth introduces bacteria. Topping off old solution dilutes the disinfectant and allows germs to grow. Always use fresh solution.
- Keep the case clean. Rinse your case with fresh solution daily, air‑dry it upside down, and replace the case every three months.
Choosing the Right Cleaning Solution
Your solution type determines your cleaning routine. Multipurpose solutions (MPS) are the most popular and clean, rinse, disinfect, and store all in one step. Even “no‑rub” MPS still require 10–20 seconds of manual rubbing for proper disinfection. For a rundown of top multipurpose products, see our roundup of best contact lens cleaners.
Hydrogen peroxide systems offer a deeper clean but require a special neutralizing case and at least six hours of soaking. Never use saline solution for cleaning—it only rinses and does not disinfect. Rewetting drops are for lubrication only and are not sterile enough for cleaning.
FAQs
Can I use tap water to rinse my contact lenses?
No. Tap water, even distilled, contains microorganisms that can cause severe eye infections. Always use fresh multipurpose solution or a hydrogen peroxide system for rinsing and storage.
How often should I replace my contact lens case?
Replace your case every three months. Also rinse it with fresh solution daily and let it air‑dry upside down to prevent bacterial growth. A dirty case can contaminate clean lenses.
Is saline solution enough to clean contacts?
No. Saline is only for rinsing, not for cleaning or disinfecting. It does not kill microorganisms. Always use a multipurpose or hydrogen peroxide solution that includes disinfecting properties.
