How it works

Bliss© Digital Therapeutics uses a VR headset and an audio headset specifically optimized to provide relief to patients by reducing pain and anxiety during medical procedures. Set up is quick and easy, with immediate reduction of patient pain and anxiety.

Bliss© includes innovative solutions developed by L’Effet Papillon over many years, leveraging the potential for virtual reality, sound, and music to alleviate patient pain.

Bliss© experiences can be tailored to the length of the applicable procedure, with sessions lasting from a few minutes to more than one hour. Because Bliss© relies on sounds and images, it can be used by all patients without regard to their age, language skills, or learning abilities.
