Specsavers are urging Falkirk area customers to stop using CooperVision contact lens solution.
The company has issued a recall alert over fears bacteria might still form on lenses.
A quality control check has found that easyvision may not offer appropriate levels of disinfection in some circumstances against high levels of a particular yeast organism.
From today, anyone with unopened bottles of CooperVision will be able to claim a refund for the product.
Specsavers say they'll temporarily use different manufacture until the issue is sorted.
A spokesperson for the company said: "CooperVision’s quality testing determined that the product may not offer appropriate levels of disinfection in some circumstances against high levels of a particular yeast organism.
"Although no complaints have been received and there have been no confirmed incidence attributed to inadequate disinfection, this action is out of an abundance of caution.
It is important you continue to clean and disinfect your soft contact lenses.
"Please cease using your easyvision easypurpose solution once you’ve secured an alternative solution.
"Please retain any open and unused bottles to obtain your reimbursement through the recall website."
