Contact lens manufacturer Johnson & Johnson (J&J) has revealed that it has recalled almost 500,000 boxes of contact lenses as a precaution since August.
In the summer, the company announced that it was recalling batches of its 1 Day Acuvue Trueye, mainly in Japan, after reports of stinging from wearers.
Initially the recall was only thought to include around 100,000 boxes but J&J has since revealed that nearly five times this amount was recalled, with 75 per cent of the boxes located in Japan.
Gary Esterow, a spokesman for the company, said it had notified authorities from all countries that had received affected lots, with the relevant government agencies now responsible for notifying consumers.
Voluntary recalls have also taken place in many European countries, including Germany, Spain, the UK, Switzerland, Ireland, Italy and Sweden.
Last month, contact lenses manufacturer Novartis won a case against J&J to protect its right to sell extended wear contact lenses in France after the pharmaceutical giant had sought to remove this right through the French courts.
