TOKYO, April 4 (Reuters) - Japanese eyeglass lens maker Hoya Corp on Thursday said the production of several of its products have stopped after a system failure, which was "most likely caused by unauthorised access" to its servers.

Hoya said the company discovered a system discrepancy in one of its overseas offices on March 30 and confirmed the disruption despite its efforts to isolate affected servers.

The company is investigating whether any of its confidential or personal data had been compromised and is cooperating with authorities to resume production as soon as possible, it said in a statement. (Reporting by Kantaro Komiya; Editing by Jacqueline Wong)
