Itchy, tired, or sore eyes are all telltale signs you may be suffering from dry eye syndrome. The condition occurs when your eyes are inadequately lubricated due to the lack or poor quality of your tears. While there are various natural causes for dry eyes, the prevalence of air conditioning, contact lenses, and electronic screens are making symptoms increasingly common.
Dry eye syndrome can prove to be irritating and limit some day to day activities, and while a lot of people will attempt to soldier on with the condition, not addressing the issue can lead to nasty complications:
- Eye infections. Your tears protect the surface of your eyes from infection. Without adequate tears, you may have an increased risk of eye infection.
- Damage to the surface of your eyes. If left untreated, severe dry eyes may lead to eye inflammation, abrasion of the corneal surface, corneal ulcers, and vision loss.
- Decreased quality of life. Dry eyes can make it difficult to perform everyday activities, such as reading or driving.
A simple solution to help alleviate dry eyes is to invest in a humidifier. By adding moisture to the air in your home or workplace, tears will evaporate more slowly making your eyes more comfortable, with humidity levels of about 45% or more being optimum for our eyes.
With hundreds of humidifiers on the market, it can be tricky to find the right product for you. To help you in your search we’ve selected 8 of the best humidifiers available to help with dry eyes.
As each machine will work at its best in a specific sized space, be sure to consider the room you would utilize a humidifier, with products such as the LEVOIT Humidifier being best suited to larger rooms and the Pure Enrichment MistAire being an excellent cost effect humidifier for smaller spaces.

Frequently Asked Questions
What is Dry Eye Disease?
A condition characterized by the inability to create adequate lubrication for your eyes, Dry Eye Disease is common and treatable. Tears, your natural eye lubricant, may be inadequate for one of two reasons. The first is that some people don’t create enough tears and the second is the production of poor quality tears. Lack of tears or poor quality tears can cause inflammation or injury to the surface of your eye.
Symptoms of Dry Eye Disease include discomfort, dry eyes, stinging, and burning. For some, these symptoms are constant while for others, particular situations activate the symptoms.
What is the best humidity level for dry eyes?
If you suffer from dry eyes, dry climates are the most aggravating to your symptoms. If possible, avoiding dry climates can remediate dry eye symptoms. However, where this is not possible, maintaining a humidity level of 45% and above is ideal for alleviating dry eye symptoms. Conversely, humidity levels that are too high could cause excess moisture in your eyes which could also be irritating.
Moreover, high humidity levels could also negatively impact your vision. Finding a balance of somewhere between 45% and 65% is optimal for dry eye sufferers.
How do I choose a humidifier for dry eyes?
The most important factors to consider when purchasing a humidifier, especially for dry eyes, are the space where you’ll use it, the mist output, water capacity, the cleaning process, and the noise it may create. Concerning space, be sure to choose a model adequate for the square footage you wish to humidify.
Depending on where you’ll use the humidifier, noise may be a consideration; you wouldn’t want a loud machine in a bedroom or shared office space. Another important consideration is the tank size; if you hope to have a humidifier that runs continuously for long periods, you’ll require a humidifier with a large tank capacity.
Which Humidifier is Best For You?
All of the humidifiers reviewed herein are effective at alleviating symptoms of dry eyes. Therefore, it’s important to consider features that are desirable to you. If you are looking for a humidifier that will run through the night, humidifying your bedroom while you sleep, be sure to select a quiet model with a large tank capacity that will not need to be refilled overnight.
Another important consideration is the square footage that the humidifier will cover. Take measurements and be sure to select a model that is suitable for your space. If the idea of coupling your humidifier with aromatherapy diffusions is appealing, be sure to select a model that accommodates oils.
Furthermore, if the convenience of operating the humidifier without having to leave your bed or seat is desirable, consider a model that comes with a remote control. Some models, as noted above, can diffuse medicated inhalants in addition to misted water. If you are interested in a humidifier that will treat symptoms of a cold, flu, allergies, or sinus issues, a feature like this is likely desirable. No matter which of the above humidifiers you select for your dry eyes, you are sure to benefit from the relief of improved humidity in your home or office.
