How Extreme Temperatures Affect Your Contact Lenses

Updated August 5th, 2025 – If you wear contact lenses, you might worry about what happens when they’re left outside on extremely hot or cold days. Luckily, a recent study found that as long as the packaging isn’t damaged, your contact lenses and their solutions stay safe to use, even in extreme temperatures. So, even if your lenses sit on the porch in the heat or cold, they should still be fine.

Let’s talk about how to take care of your lenses in different weather conditions to keep them comfortable and effective. Here are some key tips for managing your lenses in both hot and cold weather.

Hot Temperatures

Can Contact Lenses Melt?

You might be worried about your contact lenses melting in extreme heat, but rest assured, they won’t melt in your eyes or in hot environments like a car or porch. Modern contact lenses are made to withstand high temperatures, so there’s no need to stress about them melting. Your lenses are safe to wear even in hot weather.

Tips for Hot Weather

Managing your contact lenses in hot weather involves taking a few precautions to ensure your comfort and eye health:

Avoid getting your lenses wet by taking them out before swimming, soaking in a hot tub, or showering—water can lead to infections like acanthamoeba keratitis. Be mindful of sweat, too, as it can cause eye infections if it gets between your contact and your eye.
 
Lastly, protect your eyes from harmful UV rays by wearing sunglasses or contact lenses with UV protection. Daily lenses offer built-in UV protection and are a great option for sunny days. You can buy daily disposables like 1-Day Acuvue Moist at Lens.com.
 

Cold Temperatures

Can Contact Lenses Freeze?

In cold weather, you might wonder if your contact lenses can freeze. Contacts can freeze if the solution they’re stored in reaches about 5°F, but they will thaw out safely at room temperature if the packaging is intact. So, while it’s possible for contact lenses to freeze in extremely cold conditions, they won’t be damaged as long as their packaging is not compromised. Just let them thaw at room temperature before using them.

Tips for Cold Weather

Cold weather requires specific strategies to keep your contact lenses comfortable and your eyes healthy:

  1. Fight dryness by using contact-safe eye drops to maintain moisture.

  2. Drink plenty of water to keep your eyes hydrated.

  3. Stay away from direct heat like furnaces and car vents since it can dry out your eyes.

  4. Protect your eyes from harsh winds and UV rays with sunglasses or goggles.

  5. If you’re sick, avoid wearing contacts to prevent transferring infections to your eyes.

  6. Switch to glasses to give your contacts a break.

Year-Round Contact Lens Care

Proper lens care is essential for keeping your eyes healthy. Always clean and store your lenses as recommended, and stick to the replacement schedule to avoid issues. If you want to reduce the risk of infections and irritation, consider switching to daily disposable contacts. Also, give your eyes a break now and then by switching to glasses.

Avoid sleeping in your contacts since it increases the risk of eye infections. Make sure you’re getting enough sleep, too, as rest is crucial for maintaining eye health. Lack of sleep can lead to dryness and irritation, so prioritize your rest to keep your eyes feeling comfortable.

Traveling with Contact Lenses

Traveling can expose your lenses to various conditions, so it’s important to ensure they remain safe and comfortable. Here’s how to ensure they remain safe and comfortable:

Travel Tips

When traveling with contact lenses, especially by air, it’s important to keep your lenses and eyes comfortable. Always pack your contact lens case and solution in a travel-sized, TSA-approved container if you’re flying. Airplane cabins are low in humidity, so use moisturizing eye drops to keep your eyes comfortable. Remember to wash your hands thoroughly before handling your lenses, especially when traveling. It’s also a good idea to bring a spare pair of lenses and your glasses in case of emergencies.
