With over 45 million contact lens wearers in the USA and over 140 million worldwide, there are a lot of people wondering if they can bring contact lens solution on their next flight.

According to TSA regulations, you can bring contact lens solution on a plane in both your carry on and checked bags, though if packed in your carry on, the bottle should be no larger than 3.4oz/100ml.

However, if the contact lens solution is deemed “medically necessary”, you can bring larger bottles.

If you wear contacts, there is much more you need to know, though, to make sure that your next flight goes as smoothly as possible, including whether the type of contact lens solution and contact lens you wear make a difference, and more.

Can You Bring Contact Lens Solution on a Plane?

Carry on Bags

The TSA have something called the 3-1-1 Rule that only permits passengers to bring liquids, including contact lens solution (as well as gels and aerosols), in containers that are no larger than 3.4oz/100ml in a 1-quart sized bag.

This means that if you pack contact lens solution in a container that exceeds this, it will be confiscated before you can pass airport security.

However, the TSA also state that they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip.”

This includes contact lens solution.

The caveat is that these must be prescribed, labelled and declared to security officers at the checkpoint for inspection.

Checked Bags

There are no restrictions if you want to pack contact solution in your checked bags.

So, this means that you can take however many bottles of solution you want in any size without running into any issues.

Domestic vs. International Flights

The TSA only has authority in the USA, so you might be wondering what the regulations are if you are traveling internationally.

Fortunately, regardless if you’re flying domestically in the USA or internationally, the same rules apply.

So, you are only allowed to bring contact lens solution in your carry on bag if it is in a container that is no larger than 3.4oz/100ml.

By Airline

All airlines follow TSA regulations, which means that regardless if you’re flying with a regional or major air carrier, you can only bring contact lens solution on a plane in your carry on bags if the bottle does not exceed 3.4oz/100ml.

The same exceptions apply for medically necessary contact lens solution.

Can You Put Contact Solution in a Travel Bottle?

While you can transfer contact solution from a larger bottle into a smaller, travel-friendly sized bottle to adhere to TSA regulations, it is not recommended.

This is because contact lens solution is sterile, so you may introduce contaminants as you transfer the solution, which would be very bad for your eyes.

Can You Wear Contact Lenses on a Plane?

You can wear contact lenses on a plane, but it might not be the best idea.

This is because air inside the cabin is very dry and can cause dry eyes, which can make the lenses tighten in your eye and cause microscopic tears to the cornea.

You may also drift off to sleep, and if you’re wearing any contacts other than extended wear ones, this can damage your eyes.

If you do happen to fall asleep while wearing contacts, take them out as soon as possible to let your eyes breathe.

Can You Wear Colored Contact Lenses on a Plane?

If you’re planning on wearing colored contact lens, it might not be the best idea.

This is because you may be asked to remove your contact lens when they compare how you look on your ID compared to how you look in person to see the real color of your eyes.

It might not happen often, especially if you otherwise look exactly the same in your ID – i.e. you haven’t grown or shaved a beard, have a drastically different haircut etc. – but it’s still a possibility.
