Coated Glasses

Question: I have some special 'coated' glasses.  This coating is supposed 
glare from computer screens etc.  When white, or sunlight shines on them, they 
reflect a greenish color (to the light).  I think that the coating must absorb 
several colors of white light, but why cannot I notice a difference?  What 
does the absorption spectrum look like for these coatings?
---------------------------------------
Usually glasses that reduce glare do so with polarizing filters.  
Glare from terminal screens may be different, though.  There are glare 
reducing covers for most screens, but I am not sure how they work.
