Do the self-warm eye masks work?
Heated eye masks can be an effective treatment option for alleviating dry eye symptoms.
Research from 2017* indicates that heated eye masks may help manage meibomian gland dysfunction (MGD), a primary cause of dry eyes in the U.S. The study suggests that previous research has shown the optimal temperature range for treating MGD is between 89.6ºF (32ºC) and 113ºF (45ºC). In cases where the glands are severely obstructed, temperatures over 104ºF (40ºC) may be required.
However, reaching the appropriate temperature can be challenging. There’s typically a 41ºF (5ºC) difference between the heat applied to the eyelid surface and the temperature at the location of the meibomian glands. Applying temperatures of 113ºF (45ºC) directly to the outer eyelid could damage the skin.
While specific heated eye masks can achieve the necessary temperature, some individuals may need to visit a healthcare professional for treatment.
Alternatively, various heated eye masks are available for home use. A 2014 randomized controlled trial compared the effectiveness of a heated towel to a heated eye mask in treating MGD and found that the eye mask was more effective.
Further, a 2015 study on self-applied heat therapy concluded that using a portable heated eye mask may benefit individuals with MGD who experience mild to moderate dry eye symptoms.
The 2017 researchers also noted that heated eye masks can be used at home as a supplemental therapy for treating MGD. They recommend using the masks daily for 10–15 minutes as part of a consistent treatment routine.
