How did you learn to swim if you wear glasses?

[belgo]

I cannot tolerate contact lenses and whilst I can swim , my technique is virtually non existent because of wearing glasses.

I have just started swimming lessons and need to work out what to do when I have to put my head under water.

Get some prescription goggles.

Thank you. I have prescription diving googles, but they have the nose thing and I've never worn them for normal swimming.
