Rub and Rinse Contact Lens Cleaning Method Shown to be More Effective Than No Rub Technique

A study out of Australia has confirmed what eye doctors have long suspected. Rubbing your contact lenses and briefly rinsing them prior to overnight storage and disinfection is more effective at removing bacteria from the lens surface than merely placing the contacts in the case (no rub technique). Numerous multipurpose no rub contact lens solutions have been approved by the FDA  and shown to be an effective method of disinfecting contact lenses however this study shows that applying a few drops of the multipurpose solution, rubbing and then rinsing the lenses is much more effect at removing bacteria from the lens surface.

This study was done “in-vitro” meaning that it was a lab study where patients did not actually wear these lenses but the lenses were seeded with bacteria and then after the lenses were cleaned and disinfected the lenses were then testing to see how much bacteria was removed.

So the moral of the story is after removing your soft contact lenses add a few drops of the multipurpose contact lens solution, rub both sides of the lens then rinse the lens and place it in the case to disinfect overnight.
