1. A light irradiating apparatus comprising:
- a frame;
a reflecting plate attached to the frame;
a light source block formed on peripheral edges of the frame and configured and arranged to radiate a light to eyes of a user by radiating the light from the light source block to the reflecting plate, and then reflecting the light off the reflecting plate back to the eyes of the user;
a view line detection block configured to detect a view line direction of the user, the view line detection block including two electrodes, and a reference electrode, said view line detection block detecting a view line direction of said user from a potential difference between said two electrodes and said reference electrode; and
a light source control block configured to control the light radiated from said light source so as to restrict a light quantity in an area corresponding to the view line direction detected by said view line detection block.

5. A light irradiating method comprising the steps of:
-
radiating a light to eyes of a user, the light being radiated from a light source block formed on peripheral edges of a frame of a light irradiating apparatus to a reflecting plate and back to the eyes of a user; detecting a view line direction of the user based on a potential difference between two electrodes provided on the frame and a reference electrode; and controlling a light source radiating a light to the eyes of the user so as to restrict a light quantity in an area corresponding to a view line direction detected in said view line detection step.

6. A light irradiating apparatus comprising:
-
a frame; a reflecting plate attached to the frame; light source means formed on peripheral edges of the frame and configured and arranged for radiating a light to eyes of a user by radiating the light from the light source means to the reflecting plate, and then reflecting the light off the reflecting plate back to the eyes of the user; view line detection means for detecting a view line direction of the user, the view line detection block including two electrodes formed on the second surface, and a reference electrode, said view line detection block detecting a view line direction of said user from a potential difference between said two electrodes and said reference electrode; and light source control means for controlling the light radiated from said light source so as to restrict a light quantity in an area corresponding to—
a the view line direction detected by said view line detection means.
