Rub the lens even when the bottle says “no rub.” Ten seconds of mechanical rubbing removes far more deposits and organisms than soaking alone, and it is the step most people skip because the packaging told them they could.
The nightly routine
- Wash and dry your hands on a lint-free towel.
- Remove one lens and lay it in your palm.
- Apply fresh solution and rub for about ten seconds per side with a fingertip, in a back-and-forth motion rather than circles.
- Rinse thoroughly with solution — never water.
- Put it in a clean case with fresh solution, filled enough to submerge it.
- Repeat with the second lens and close both lids firmly.
- Soak for the full minimum time on the bottle — usually four to six hours.
The three habits that undo all of it
Topping off. Adding fresh solution on top of yesterday’s dilutes the disinfectant until it no longer works. Empty the case completely, every single time. This is the most common error in lens care.
Keeping the case. Biofilm forms on the plastic and solution stops penetrating it. Replace every three months at most, and ideally with every new bottle. See the case guide.
Water. Tap water carries Acanthamoeba. Not for rinsing lenses, not for rinsing the case, not for topping up. See contacts and water.
The case matters as much as the lens
Every morning, after your lenses go in:
- Empty it completely
- Rub each well with fresh solution and a clean fingertip
- Rinse with solution
- Leave it open, face down on a clean towel to air-dry
That last step is the one almost everyone misses, and it is what prevents biofilm. A closed, damp case is an incubator.
Which solution
Multipurpose cleans, rinses, disinfects and stores. It is the everyday default and needs the full soak time to work.
Hydrogen peroxide disinfects more powerfully and leaves no preservatives, which makes it the answer for sensitive eyes. Two absolute rules: never put it directly in your eye, and only use the case it came with — the platinum disc is the neutraliser. Give it the full six hours.
Saline does not disinfect. It rinses. Storing lenses in saline is storing them in salty water. Full comparison in solutions explained.
Rigid lenses use their own cleaner and conditioning solution — soft lens multipurpose will not condition them correctly.
If deposits keep building
Hazy vision or discomfort by week three of a monthly is a pattern, not bad luck. Options in order:
- Add a weekly enzymatic cleaner for protein
- Switch to a peroxide system, which cleans more aggressively
- Move to a deposit-resistant material — see Air Optix
- Move to dailies and stop cleaning altogether
That last option is not defeat. If your routine is the weak point — and for most people it is — removing the routine is the safest fix available.
Replacement dates are not negotiable
No cleaning routine makes a lens last past its schedule. A monthly is monthly from the day the blister is opened, whether you wore it twice or thirty times. See do contacts expire.
