This cool goggle helps us to relax from all our daily life’s strains. It has dual mode of operation. One mode is reading mode while the other is relaxing mode. Reading mode is suitable while reading and writing. It has a led to which a light sensor is attached, that adjusts according to the sensitivity curve of the human eye, enabling brightness levels of the led light to be adjusted more precisely. Hence the strain imposed on the eye while reading or writing is greatly reduced. Reading a few articles I came to know that our eye color changes with our mood.In relaxing mode,a color sensor placed in the goggle would detect the color of the eye, that indirectly reflects our mood.A chip embedded on the goggle then changes the color of the glass according to the mood, which then gradually changes to a cool mood color, thus the person is freed of from his/her tension. It also has telescopic and microscopic features in it. It is said that only in humans that the eye acts as a window into the individual mind, wearing this ‘Cool goggle’ helps people to have a peaceful mind as it reduces the strain and helps us to relax.
