Halo uses non-invasive Low-Level Light Therapy (LLLT) that is designed to be gentle and safe for the eyes when used as directed.
Most people naturally keep their eyes closed because it feels more relaxing and spa-like, but you can comfortably use Halo either way.
The red light is designed to penetrate deeply enough to support the glands effectively, while still being gentle and safe for the delicate eye area.
