Have you ever noticed how your eyes feel more comfortable in humid conditions, especially if you’re a contact lens wearer? I was definitely struck by it when I went to Hong Kong over the Easter break. Fun fact: Hong Kong is actually considered to have a subtropical climate, which means that humidity can reach a full 100% and rainstorms are not uncommon during specific times of the year. High humidity levels can significantly alleviate the symptoms of dry eyes by reducing tear evaporation and maintaining a stable tear film. This is especially beneficial for contact lens wearers, who often suffer from increased eye dryness.

Understanding Humidity and Eye Comfort

Humidity refers to the amount of water vapor present in the air. In environments with high humidity, the air has more water vapor, which can help prevent the rapid evaporation of the tear film that covers the surface of our eyes. This tear film is crucial for maintaining eye health and comfort, particularly for those who wear contact lenses.

The Benefits of High Humidity for Eyes

In humid climates, people often experience fewer dry eye symptoms because the moisture in the air helps keep the tear film from evaporating too quickly. This natural moisturising effect is particularly helpful for contact lens wearers, as it can reduce the irritation and discomfort associated with dryness and I must admit, in Hong Kong my eyes never felt so good even when I have overwore my contacts.

Research on Humidity and Contact Lenses

Studies have shown that environments with a humidity level of around 45% or higher are ideal for eye comfort. Conversely, low humidity can lead to increased tear film evaporation, causing dryness and discomfort. This is why contact lens wearers might find their eyes becoming particularly irritable in dry, air-conditioned rooms or during the winter months when indoor heating can reduce humidity levels.

Practical Tips to Manage Eye Comfort

To combat dry eye symptoms and improve comfort while wearing contact lenses, consider the following tips:
Use a Humidifier: Adding a humidifier to your home or office can help maintain an optimal level of humidity, especially in dry conditions. This can be particularly beneficial when you’re spending long hours in air-conditioned or heated environments.

Stay Hydrated: Drinking plenty of water throughout the day helps maintain your body’s natural moisture levels, including the moisture in your eyes.
Take Breaks: Regular breaks from screen time can reduce eye strain and help maintain moisture levels in your eyes.
Opt for Moisturising Drops: Using lubricating eye drops approved for use with contact lenses can provide additional relief from dryness.

Increasing Environmental Humidity

For those living in dry climates, increasing the humidity level can provide significant benefits:
Avoid Direct Airflow: Keep air vents directed away from your face to reduce the risk of drying out your eyes.
Use Plants: Indoor plants can naturally increase the humidity level in a room.
Open Water Sources: Small open water sources, like indoor fountains, can also add moisture to the air.


Maintaining the right humidity level is crucial for ensuring eye comfort, particularly for contact lens wearers. By understanding the relationship between humidity and eye health, and by implementing simple measures to manage indoor air quality, you can significantly enhance your eye comfort. Embrace these tips to ensure your eyes are protected and comfortable, no matter the climate or environment.
