Query: dont see how it helped me

i work infront a computer for many hours, and my eyes are killing me. i thought that this thing will help but tell you the truth i just see how it suppose to help, because it didnt. that screen comes with a useless cord that makes your thing that you are missing the part which suppose to connect the this cord, it comes with two "hangers" to attach the the screen to the pc monitor, but after using it for a while it just didnt helped. this product is a lie they saying that this product helps your eyes, but i dont really know where they take this from
