further comprising means ( 35 ) for directing the light unit ( 31 ) to the determined dominant eye of the user.

12 . Device ( 30 ″) as claimed in claim 1 ,

further comprising monitoring means ( 36 ) for monitoring the cognitive engagement of the user,

wherein said control unit ( 32 ) is adapted to control said light unit ( 31 ) based on the monitored cognitive engagement of the user.

13 . Device ( 30 ″) as claimed in claim 12 ,

wherein said monitoring means ( 36 ) comprises means for measuring the brain activity of the user during imperceptible light stimulations, and wherein said control unit ( 32 ) is adapted to control said light unit ( 31 ) based on the measured brain activity.

14 . Method for cognitive enhancement of a user comprising the steps of:

providing an imperceptible light stimulation to the user, and

controlling said imperceptible light stimulation such that it is provided less than 5 seconds before the execution of a cognitive activity by the user.

15 . System for use by a user comprising:

a user device ( 40 ) requiring the execution of a cognitive activity by a user and

a device ( 30 , 30 ′, 30 ″) as claimed in claim 1 for cognitive enhancement of the user,

wherein said user device ( 40 ) is adapted to provide an information to said device ( 30 , 30 ′, 30 ″) for cognitive enhancement of the user when a cognitive activity is to be executed by the user.
