If they had denatured, you wouldn't be able to see out of them would you?
The seals on the contacts were intact and the box (of six individual contacts) was unopened.
I was referring to Melbourne, Australia. The seal on my mother's solution packet was damaged which we queried. The individual bottles were sealed appropriately though.
Thanks for your time in answering my question.
Yes. The contact lens material may have denatured somehow (changed its chemical structure). Also, if the seals look damaged, potentially the contact lenses have become contaminated. Might I suggest that you not take undue risks with your eyes by attempting to save money through buying your contacts in "a hot country" and having them shipped to you in a cooler one?
