While most bright light treatments for seasonal affective disorder are designed for the eyes, the VALKEE is actually designed to be worn like a pair of earbuds, blasting the light towards your brain via your ear canals. According to their website it targets the brain’s photosensitive areas which can cause depression and mood swings when not receiving enough light, and is apparently more affective than blasting the eyes with light since the ear canal is the thinnest part of your skull. Now I hate to be skeptical about this approach, since it does seem to have a logical advantage. But ~$240 (€185) is a hefty chunk of change for what are essentially in-ear LED flashlights.
