Can I take contact lens solution on a plane?
Yes — but it's a liquid. Cabin bottles must be 100ml / 3.4oz or smaller. Larger bottles can be allowed under medical exemption if you declare them.
Does contact lens solution count as a liquid for airport security?
TSA classes contact lens solution as a liquid under 3-1-1, but allows 'reasonable quantities' larger than 3.4oz under a medical exemption if you declare it. UK and EU rules are similar — declare any bottle over 100ml at the start of screening.

Frequently asked questions
Do daily contact lenses count as a liquid for TSA?
The lenses themselves are not liquids and have no size limit. The saline inside individual daily-disposable blister packs is so small it doesn't trigger the rule. But standalone contact lens solution bottles are liquids and fall under 100ml.
Can I take more than 100ml of contact lens solution?
Yes, under a medical exemption — declare it before screening starts. TSA, UK and EU all allow 'reasonable quantities' for the trip when declared.
