Can I use contact lenses that have frozen (and then thawed, perhaps multiple times)?

I accidentally left a box of new contact lenses in a house that is not going to be used much this winter, and so won’t be heated. Everything in the house will freeze. If there’s a warm day between two cold ones everything will thaw out, then freeze again.

I initially brought them up in the summer when I was spending a lot of time there. I meant to bring them home in the autumn before it got cold, but forgot.

Will the contact lenses still be ok to use by the time I get up there next, which will be about a month from now? They are Acuvue brand soft contact lenses, packaged in buffered saline (58% water).

Contact lenses are expensive.
