A step-by-step beginner's routine for cleaning your contact lens case, choosing solution, and storing colored contacts safely without damaging the lenses.
Quick answer
Empty and rinse both case wells with fresh multipurpose solution every time you remove your lenses, then air-dry the case upside down with caps off. Replace the case every three months, and never top off old solution or use tap water. This routine takes under a minute and protects both your eyes and your lenses.
What you actually need before you start
Keep three things next to your case: a bottle of multipurpose solution that states it is suitable for soft contact lenses, a clean lint-free cloth or paper towel, and a small calendar reminder for your replacement date. You do not need a separate cleaning device unless your lens manufacturer specifically requires one. If your solution bottle does not list soft lens compatibility, do not use it. A common beginner mistake is buying saline or rewetting drops as a main storage solution; those do not disinfect, so they belong in your bag, not your case.
Solution habits that keep lenses comfortable
Use fresh solution every single time you store your lenses. Topping off a partly filled well dilutes the disinfectant and leaves older solution behind, which is one of the most common causes of irritation. Fill each well to the marked line, close the cap tightly, and store the case upright. If you wear daily disposable lenses such as One Pick Meari Sun Glow 1Day or ORIANA MUNE Gray 1Day, you will not store them overnight at all, so your solution routine is mainly about rinsing the case before it dries. Monthly lenses like REBORN RED Rosy Cream 1Month need the full soak-and-disinfect cycle every night.
How to clean the case without scratching it
Rinse each well with solution and rub the inside with a clean finger, then tip the solution out. Do not scrub with a tissue, cotton bud, or rough sponge; those leave fibers and micro-scratches where bacteria can settle. Once a week, give the case a longer rinse and let it air-dry completely before you close it. Never use tap water, soap, or a dishwasher on a lens case, even if the label says the plastic is sturdy. Water and detergent residue can cling to the plastic and transfer to your lens.
When to replace your case and solution
Replace the case every three months, or sooner if you notice cracks, cloudy plastic, or a persistent film that rinsing will not remove. Write the replacement date on the case base with a marker so you do not have to remember it. Check your solution bottle for its discard-after-opening date; most multipurpose solutions should be used within the period printed on the label, and an expired bottle will not disinfect reliably. If you travel, pack a spare case and a small sealed bottle rather than decanting solution into an unlabeled container.
Your step-by-step case care routine
- Wash and dry your hands: Wash with soap and water, then dry with a lint-free towel before you touch the case or lenses. Checkpoint: damp hands can transfer water and bacteria to the case.
- Empty both wells: Pour out the old solution immediately after removing your lenses. Do not leave lenses sitting in used solution. Common mistake: leaving old solution in the well overnight and reusing it.
- Rinse with fresh multipurpose solution: Fill each well about halfway, swirl, and tip the solution out. Repeat once if the case looks cloudy. Checkpoint: the solution should look clear, not stringy or cloudy.
- Air-dry upside down with caps off: Place the open case upside down on a clean paper towel so water can drain out and air can circulate. Common mistake: closing a wet case, which traps moisture and encourages microbial growth.
- Refill with fresh solution before storing lenses: When you are ready to store monthly lenses, fill each well to the line with new solution and tighten the caps. Checkpoint: never top off a partly filled well.
- Mark your replacement date: Write the date three months from today on the case base, or set a phone reminder. Next step: replace the case on that date even if it still looks clean.
How your lens type changes the routine
- One Pick Meari Sun Glow 1Day: One Pick Meari Sun Glow 1Day is a daily disposable lens designed by I-SHA Korea for comfortable daily wear with a subtle, sunlit warm tone. Because it is a 1Day lens, you discard it after each wear instead of soaking it overnight, so your case is only used for rinsing and drying. That makes case hygiene simpler, but you still need to clean and air-dry the case so it is ready when you open a fresh pair.
- REBORN RED Rosy Cream 1Month: REBORN RED Rosy Cream 1Month is a monthly-wear lens with a creamy rosy tone, made in Korea and designed by I-SHA Korea. Monthly lenses are stored in solution every night, so the quality of your solution and the cleanliness of your case directly affect comfort across the month. Fresh solution and a dry case matter more here than with daily lenses.
- ORIANA MUNE Gray 1Day: ORIANA MUNE Gray 1Day is a daily disposable lens with a soft gray tone, designed by I-SHA Korea for a clean, refined look. Like other 1Day lenses, it does not need overnight storage, so beginners can focus on rinsing and drying the case rather than managing a long soak. It is a practical starting point if you are still building your care routine.
