Contact lens solution is allowed on planes, but only in small quantities. Most airlines follow the 3-1-1 rule, meaning containers holding liquids must not be larger than 3.4 ounces (100 ml). If you need a larger amount of contact lens solution, it's best to pack it in your checked luggage or buy it after you arrive at your destination. Some contact lens solutions may contain chemicals that trigger alarms during screening, so it's recommended to declare them to security officers beforehand. To avoid the hassle, you may want to consider using daily disposable lenses or rewetting drops to keep your contacts moist during the flight.

Contact solution is allowed in carry-on baggage but must be under 100ml
Contact lens solution is considered an over-the-counter medication and is allowed in carry-on baggage. However, it must adhere to the standard liquid restrictions for carry-on luggage, meaning that the container must be 100ml or less. This rule applies in most countries, including the US and Canada, though allowances may vary depending on the specific airport and the screening staff's interpretation of the rules.
In the US, the Transportation Security Administration (TSA) considers contact lens solution to be a medically necessary liquid and allows larger amounts in reasonable quantities. However, any amount over 3.4 ounces (100ml) must be declared to security officers at the checkpoint for inspection and placed in a separate bin from your other belongings. Some contact lens solutions contain chemicals that may trigger an alarm during screening and may not be permitted through the checkpoint, so it is recommended to place larger amounts in checked baggage.
Similarly, in Canada, the Canadian Air Transport Security Authority (CATSA) considers contact lens solution to be an essential non-prescription medication, and its website states that volumes greater than 100ml are allowed in carry-on baggage. However, individual airports in Canada may interpret this rule differently, and some travellers have reported being told that contact lens solution must adhere to the standard liquid restrictions.
To avoid any issues, it is generally recommended to carry contact lens solution in containers of 100ml or less in your carry-on baggage. Smaller containers are readily available in most brands, and you can always purchase additional solution at your destination if needed. Alternatively, you can pack a larger bottle in your checked baggage to ensure you have enough for your trip.
Overall, while contact lens solution is generally allowed in carry-on baggage, it is best to follow the liquid restrictions and pack containers of 100ml or less to avoid any potential issues during airport security screening.

Larger amounts of contact solution must be placed in checked baggage
While you can bring contact lens solution on a plane, it is recommended that larger amounts of contact solution be placed in checked baggage. This is because there are restrictions on the amount of liquid that can be taken onto an aircraft in carry-on luggage. The specific rules and allowances vary depending on the country and airport, but generally, only small amounts of liquid are permitted in carry-on baggage. For example, in the US, the Transportation Security Administration (TSA) allows larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities, but they must be declared and may be subject to additional screening. Similarly, in Canada, the CATSA website states that contact lens solution is considered an essential non-prescription medication, and volumes greater than 100 ml are allowed in carry-on baggage. However, one person commented that when they contacted the airport, they were told that contact solution falls under the liquid category and must be less than 100 ml.
To avoid any issues, it is generally recommended to place larger amounts of contact solution in checked baggage. This also ensures that you have your preferred brand and formula, as it may not be available at your destination. When packing contact solution, it is important to only use TSA-approved, travel-sized bottles for your carry-on luggage. It is also recommended to buy travel-size bottles of contact solution rather than transferring solution from a larger bottle into a smaller one, as this can introduce contaminants and put your eyes at risk for infection. Additionally, consider bringing a pair of glasses and an extra pair of contact lenses as a backup in case of any issues with your contact lens solution or unexpected eye infections or injuries. Overall, by following the guidelines for carry-on and checked baggage, you can ensure that you have enough contact solution for your trip and maintain the health and safety of your eyes.

Some contact lens solutions may not be permitted through security due to certain chemicals
Contact lens solution is allowed by the TSA in reasonable quantities, but it must be declared to security officers at the checkpoint for inspection. Any liquids that alarm during screening, testing positive for certain chemicals, may not be allowed through the screening checkpoint. Some contact lens solutions contain chemicals that typically trigger an alarm and may not be permitted through security. It is recommended that contact lens solutions over 3.4 ounces (100 ml) be placed in checked baggage.
Different countries and airports may have varying interpretations of the TSA rules, so it is advisable to check with the specific airport or country of travel. For example, while a large shared bottle of saline solution was allowed in carry-on baggage at a US airport, it was not permitted at Heathrow or Amsterdam airports.
To avoid any issues, it is recommended to purchase travel-sized bottles of contact lens solution, which typically hold about 2 ounces (60 ml) of liquid and are designed to meet TSA requirements. These can be conveniently packed in carry-on baggage, ensuring compliance with security regulations. It is also suggested to bring enough solution to last throughout the trip, considering the possibility of not finding the preferred brand or formula at the destination.
If you are unable to find travel-sized bottles or wish to bring a larger quantity, it is advised to place the contact lens solution in checked baggage. This option allows you to carry your preferred brand and formula while avoiding potential issues at the security checkpoint. By following these guidelines, you can ensure that you comply with the regulations and have a smooth travel experience regarding your contact lens solution.

Contact lens wearers can buy TSA-approved, travel-sized bottles of solution
Contact lens wearers should be aware of the rules and restrictions around bringing contact lens solution onto a plane. While it is possible, there are some important considerations to keep in mind. Firstly, it is recommended to buy TSA-approved, travel-sized bottles of contact lens solution, which typically hold about 2 ounces (60 ml) of liquid. This should be enough for a week or two, but if you are travelling for a longer period, it is advisable to pack more than one bottle.
It is important not to transfer solution from a large bottle into a smaller bottle, as this can introduce contaminants and put your eyes at risk of infection. Instead, it is suggested to purchase travel-sized bottles specifically designed for this purpose. These can often be found at airports, and you can also pack a regular-sized bottle in your checked luggage to ensure you have your preferred brand and formula.
When going through security, contact lens solution is typically considered a liquid and must follow the standard liquid restrictions. In the United States, the TSA allows larger amounts of medically necessary liquids, but these must be declared to security officers and may be subject to additional inspection. Some contact lens solutions contain chemicals that may trigger alarms during screening and may not be permitted through the checkpoint. Therefore, it is recommended to place larger amounts of contact lens solution (over 3.4 ounces or 100 ml) in your checked baggage.
Additionally, it is always a good idea to bring a pair of glasses when travelling, even if you do not plan on wearing them. This will provide a backup option in case of any issues with your contact lenses or if you lose or damage them during your trip. You may also consider daily disposable lenses for travel, as they can be more convenient and hygienic when away from home.

It is recommended to bring glasses and an extra pair of contact lenses when travelling
When travelling, it is recommended that you bring glasses and an extra pair of contact lenses. This is because, despite contact lens solution being allowed on planes, there are often strict rules regarding the amount of liquid you can take through security. While some sources suggest that contact lens solution is considered an essential non-prescription medication and therefore allowed in volumes greater than 100ml, others state that it falls under the standard liquid restrictions. To avoid having to dispose of your solution at security, it is recommended to buy travel-sized bottles of contact lens solution that comply with TSA guidelines. These travel-sized bottles typically hold around 2 ounces (60ml) of liquid, which should last one to two weeks. If you are travelling for longer, it is advisable to bring multiple bottles. Additionally, you can pack a regular-sized bottle in your checked luggage to ensure you have your preferred brand and formula.
It is worth noting that some contact lens solutions may contain chemicals that trigger alarms during security screening and may not be permitted through the checkpoint. Therefore, it is recommended to declare any medically necessary liquids to security officers and follow their instructions. To avoid the hassle of dealing with contact lens solution altogether, some travellers opt for daily disposable lenses, which are convenient and hygienic for travel. These lenses come in individual packs with enough solution to rinse the lens if needed.
In summary, when travelling, it is advisable to bring glasses and an extra pair of contact lenses as a backup. By following the guidelines for liquids and purchasing travel-sized bottles of contact lens solution, you can ensure you have enough for your trip. Alternatively, switching to daily disposable lenses can eliminate the need for contact lens solution altogether, providing a hassle-free option for travellers.
