Children in Gloucestershire are being advised not to wear swimming goggles because they are a "safety hazard".
The county council says it is not banning goggles
The county council says it is following national safety advice, but some parents have complained.
Parent Julie Douglass said: "I think it is very silly. [It] is taking away children's ability to become confident in the water."
But UK education officials say swimming goggles "...should only be worn in exceptional circumstances."
The Association of Advisers and Lecturers in Physical Education said such circumstances include when there are "...chemicals in the water that could adversely affect pupils' eyes."
But Mrs Douglass said: "I want them to prove to me what these great goggle-wearing accidents are."
Susan Robbins, from Gloucestershire County Council, said the authority was not banning wearing goggles.
"What we're doing is giving schools advice which is based on national safety advice and we're saying children shouldn't be wearing goggles for school swimming lessons. It is a safety hazard," she said.
