I slept in my contacts and woke up with both eyes red and swollen. they don't itch but they feel heavy to open and have alil mucus coming out of them.

CTL Over wear: Sleeping in contact lenses that are not designed for this will potentially result in significant ocular surface irritation, possible infection, scaring, pain, and loss of vision. First thing you shoul do is remove the contacts, use gentle artificial tears like refresh tears. If you have significant discomfort, photosensitivity, or decreased vision after discontinuing the contacts, u should see doc.
