Product description Who is the mask suitable for? The eye mask is basically suitable for everyone: whether for man or woman, whether for adults or children. Why the mask is recommended? The eyelid has glands that produce an oil with the consistency of olive oil. This oil helps to protect the tear film from drying out. Often, glands that produce thick secretions cause them to become blocked. The blockages can be loosened by warming up and thus a stable tear film can be provided. How does it work? The heated eye mask provides deep, intensive heat therapy for the treatment of: dry eye syndrome, meibomian gland dysfunction (MGD) and blepharitis. It enables the glands to function properly and ensures that the eyes recover immediately. The mask is easy to use and, thanks to the USB adapter, can also be used on the go (e.g. with a USB port on a power bank, laptop or in the car). It has an elastic band for easy and comfortable attachment to the head. There are 3 temperature levels from 40 C to 60 C and an automatic switch-off function as soon as the timer has expired. After use, your eyes will feel fresh and refreshed. 1. Connect the charging cable to the cable of the eye mask 2. Plug the USB cable into a 5V / 1-2A USB port. A USB cable is included. 3.
