My dog would squint when I got near her eye when it was injured. It was watery and swollen. But that was an injury since it was scratched, not some sort of allergic reaction.
I don't know too much about Lhasa Apsos, except that they are similar to Shih Tzus. Do you trim the eyelashes? I know that the Shih Tzus often get eye infections from their long eyelashes if they're not trimmed.
I know someone's dog whose eye did get swollen for a day due to allergies and it gradually calmed down without ever visiting the vet.
Call a 24 hour vet for advice on what to do in the meantime before your vet opens office. I usually do this and if the condition doesn't improve, I take my dog first thing in the morning to my vet when they open.
