Oulu based Valkee is studying and manufacturing bright light treatment device that deliveres the light more directly to the brain, saves eyes, allows user to move around while treatment and makes the treatment significantly shorter.
The main issue here is that it's really hard to believe this method is really working. You can evaluate the idea next time you turn your face towards the sun. -Is it your eyes or the tissue behind those, that enjoys the sun.
