Theory of Letsgoo glasses:

It's a lot like the welder's goggles. Our eyes also need some gears to protect from the blue light.

Letsgoo lenses are made with the special blue-light blocking polymer, directly incorporated into the lens materials, which restricts HEV(high energy visible) blue light

and UV that will do harm to our eyes, while allowing the beneficial light.

Since the the spectrum of the  blocking is mostly non-visible, the glasses are almost completely transparent.
