They are present everywhere, from the clear blue sky, to the fluorescent lamp in your room to anything that looks blue. Blue light falls within the range after ultraviolet lights, therefore are not protected from with the use of a normal UV sunglasses.
The color known to block blue light is yellow thus blue-blockers lenses will have a certain yellow tint in them. They can come in the form of different shades of yellow to amber and to plum. The lenses in our human eye with age turns yellow gradually, providing a certain filter in the eye from blue light.
