What Is The 3:1:1 Rule For Contacts?
The 3-1-1 rule is a TSA guideline that limits how much liquid travelers can bring in a carry-on, including contact lens solution. Each liquid container must be 3.4 ounces or smaller, all containers must fit in one quart-sized clear bag, and each traveler is allowed one bag. The rule is designed to standardize liquid restrictions for air travel. For contact lens users, it determines what size solution bottles can be packed in a carry-on.
