How to Prevent and Treat Dry Eyes from CPAP Machines

Updated: Jun 5

CPAP machine Dry Eye treatment

Dry eyes can be an uncomfortable and bothersome side effect experienced by some individuals undergoing CPAP therapy. CPAP (Continuous Positive Airway Pressure) machines are a vital treatment for sleep apnea, ensuring uninterrupted breathing during sleep. However, the continuous airflow from the CPAP machine can lead to dry eye symptoms, affecting the overall comfort and adherence to therapy. In this comprehensive guide, we will delve deeper into what CPAP is, what dry eye is, the connection between CPAP machines eye care and dry eyes, and most importantly, explore a range of effective strategies to prevent and treat dry eyes from CPAP machines, making the therapy journey more enjoyable and successful.

What is CPAP?

CPAP, an acronym for Continuous Positive Airway Pressure, is a medical device designed to address obstructive sleep apnea—a condition characterized by repeated breathing interruptions during sleep. The CPAP machine operates by delivering a continuous flow of air through a mask, ensuring the airway remains open, and normal breathing is restored during slumber.

What is dry eye?

Dry eye, also known as keratoconjunctivitis sicca, is a condition in which the eyes fail to produce sufficient tears or produce poor-quality tears, resulting in insufficient lubrication and moisture on the ocular surface. The discomfort associated with dry eyes may manifest as redness, itching, burning sensations, light sensitivity, and even temporary blurred vision.

How can CPAP cause dry eyes?

The mechanism behind CPAP machines causing dry eyes lies in the continuous airstream directed towards the airway. This gentle breeze can inadvertently increase tear evaporation, leading to dryness and irritation in the eyes. Moreover, an ill-fitting CPAP mask or air leakage from the mask can redirect the airflow toward the eyes, further exacerbating dry eye symptoms.


Prevent Dry eyes from CPAP machine

Use a humidifier with your CPAP machine:

Incorporate a humidifier into your CPAP setup to add moisture to the air you breathe. A CPAP machine with a built-in humidifier or a standalone humidifier attached to your CPAP can significantly alleviate dry eye symptoms and ensure a comfortable therapy experience.

Choose a mask that fits well and does not leak air:

Selecting the right CPAP mask is crucial to prevent air leakage and direct airflow away from the eyes. Investing in a well-fitted mask that maintains a secure seal will not only improve CPAP therapy effectiveness but also reduce the likelihood of dry eye discomfort.

Avoid using oily skin products near your eyes:

Be mindful of applying oily or greasy skin products, such as creams or lotions, near the eyes before bedtime. These products have the potential to block tear ducts or interfere with tear film production, contributing to dry eye symptoms.

Blink frequently:

During CPAP therapy, make a conscious effort to blink more frequently. The act of blinking helps spread tears across the ocular surface, preventing rapid evaporation and promoting eye lubrication.

Take breaks from your CPAP machine throughout the night:

Where possible, incorporate short breaks from wearing the CPAP mask during the night. These brief intermissions allow your eyes to rest and recover from the continuous airflow, reducing the risk of dry eye symptoms.


Dry eyes treatment from CPAP machine

Use artificial tears or eye drops:

Over-the-counter artificial tears or lubricating eye drops can provide immediate relief from dry eye symptoms. Regularly applying these drops throughout the day or before bedtime can keep your eyes moist and comfortable, enhancing the CPAP therapy experience.

Apply a warm compress to your eyes:

A warm compress can stimulate tear production and soothe dry eyes. Gently place a warm, damp cloth over your closed eyes for a few minutes daily to encourage natural lubrication.

Use a sleeping mask that covers your eyes:

Consider using a sleeping mask that covers your eyes to shield them from the continuous airstream. This protective barrier can reduce tear evaporation and provide much-needed moisture to the ocular surface during CPAP therapy.

See an eye doctor if your dry eyes are severe:

If your dry eye symptoms persist despite preventive measures and home treatments, it is essential to consult an eye doctor or an ophthalmologist. They can provide personalized recommendations and potentially prescribe medicated eye drops or advanced therapies for more severe dry eye cases.


Dry eyes are a common side effect experienced by some individuals using CPAP machines, but they need not hinder a successful sleep apnea treatment journey. By implementing a combination of preventive strategies and effective treatments, you can effectively manage dry eye symptoms and achieve improved comfort during CPAP therapy. Utilize a humidifier, choose the right mask, avoid oily products near the eyes, blink frequently, and incorporate short breaks from your CPAP machine. Additionally, consider using artificial tears, warm compresses, and eye-covering sleeping masks to alleviate dry eye discomfort. If dry eyes persist or worsen, do not hesitate to seek professional advice from an eye doctor. With the right approach, you can enjoy a comfortable and successful CPAP therapy journey, ensuring restful sleep and overall well-being.

The comprehensive advice provided in this guide helped me better understand the connection between CPAP machines and dry eyes. The tips on using artificial tears and taking breaks during the night were particularly helpful. The only reason for not giving it a full 5 stars is that I wish there were more visuals or video demonstrations for some techniques.”
