The quality of this item is even lower than a pair of sunglasses you would buy at a dollar store.  They are flimsy, light weight and made out of materials that you would find in a quarter toy machine.
I purchased these for the "red" lenses.  The picture shows a red lense.  While the lense is colored red, you can barely see the red.  These are way to see through (not demonstrated in the photo).

I purchased it for a halloween costume, and in order for me to get the desired effect i wanted, I have to tape the lense overtop of another paid of sun glasses.

If you want a cheap pair to look like Elvis or something, these are probably good.  If you are looking at these because they are read, find something else.
Don't pay more than a dollar for there
