Yes, a fan can cause or worsen dry eyes because the airflow makes your tears evaporate more quickly. Thuisarts lists drafts and fans as causes of faster tear evaporation. Therefore, do not point the fan directly at your face; choose a lower setting and place it at a distance.
Why does a fan cause dry eyes?
Your eye is covered with a thin layer of tears. This layer protects the surface of the eye and keeps it moist. If air moves quickly across your eyes, it evaporates more quickly, and your eyes may feel burning, gritty, or tired. According to Thuisarts, drafts, smoke, fans, and air conditioning can cause tears to evaporate more quickly. Blinking less, for example when working at a screen, and wearing contact lenses also play a role. This means that a fan blowing directly onto your desk when working from home can worsen the symptoms.
Does humidity also play a role?
Yes. The RIVM states that eyes feel drier when relative humidity is low: at around 30 percent or lower, dryness of the eyes becomes noticeable, especially in people who wear contact lenses. According to the same report, the average humidity in a living room during the heating season is around 45 percent. Many people therefore do not experience problems, but in a very dry home, a fan can make it just a little too dry. The RIVM also warns that the sensation of dry air does not always mean that the humidity is low: poor ventilation, high temperatures, and air pollution can cause the same sensation.
How to use a fan without dry eyes
A few small adjustments often make a difference. Direct the airflow along your body instead of at your face, for example at your legs or the wall next to you. Choose the lowest setting that you still find comfortable. Use oscillation so that the air does not continuously blow on the same spot. Place the fan further away, because the airflow becomes stronger as you get closer. Consciously blink more often when looking at a screen. Thuisarts also recommends avoiding areas close to fans and air conditioning and using artificial tears if the symptoms persist.
| Situation | What you can do |
|---|---|
| Fan blowing directly at your face | Move it or turn on oscillation |
| Screen work with a fan | Place it at a distance and blink more often |
| Sleeping with a fan | Use a low setting or sleep mode, and do not point it at your head |
| Symptoms persist | Contact your GP |
Direct answer: a fan can cause dry eyes because the airflow makes tears evaporate more quickly. Reduce the symptoms by not directing the airflow at your face, choosing a low setting, and keeping it at a distance. If the symptoms persist, see your GP.

A fan is not a medical device and does not cure dry eyes. If you have long-term or severe symptoms, such as pain, light sensitivity, or a red eye, contact your GP.

Frequently asked questions
Is sleeping with a fan bad for your eyes?
It can be, if the airflow blows on your face all night. Point the fan elsewhere, use a low setting or sleep mode, and try the timer so that it turns off after a while.
Does a humidifier help with dry eyes caused by a fan?
That depends on the cause. The RIVM warns that humidifiers are not always a clear solution and that some types can spread microorganisms if they are not kept clean properly. Therefore, adjust the airflow first.
When should I see my GP about dry eyes?
Thuisarts advises contacting your GP if you experience light sensitivity, sudden vision loss, eye pain, a red eye, or if self-care does not help.
Does a tower fan cause less dry eyes than a pedestal fan?
Not necessarily. What matters is how strongly the airflow hits your face. A setting and placement that blows along your body do more than the type of fan.
