And some more for the pile of evidence at hand.

"In order to protect their eyes from the harmful and dangerous effects of the blue light, it is best for individuals to use sunglasses with polarized lenses. This lens coating provides suitable and highly effective protection from the dangerous ocular diseases that this light can cause."
"Exposure to ultra violet light, results in a number of highly dangerous diseases and medical problems. Individuals usually have to deal with the trouble of acquiring suitable protection from ultra violet light, while working outdoors in the sun.
People, who are engaged in various daily outdoor activities, have to deal with the painful glares of the sun in their eyes which besides being inconvenient might also result in acute visibility problems. The reason for the discomfort are the horizontal glares of the sunlight on the roofs, roads and water surfaces, which reflect the high density ultra violet light into the eyes. Prolonged exposure can result in a number of highly painful visibility problems.
Blue light is a form of ultra violet light, which is included in the ultra violet light spectrum[citation needed], and causes severe damage to the eyes, with prolonged exposure."
Besides an astonishing amount of technical balderdash in that blog, there is no mention of the Moon in it at all. There are several references to the Sun and sunlight, though.
The part saying "blue light is a form of ultra violet light, which is included in the ultra violet light spectrum" is ludicrous. Ultraviolet (UV) light has wavelengths
shorter than violet light, and is invisible. Blue light has wavelengths
longer than violet light and
is visible. I'd like to know where the author of that particular blog entry got this "information"? I bet it's from the marketing department of one of the sunglasses vendors they're advertising, not one of their technical departments, if they even have any.
That you would take this at face value shows an incredible lack of savvy on your part. That you'd trot it out here as evidence for something is even more ridiculous. You need to find better sources of information.
And yes, blue light does come from the moon.
I presume you mean the Moon reflects some blue light, which is true, but how much blue light does the Moon provide?
The intensity of moonlight varies greatly depending on the lunar cycle but even the full Moon typically provides only about 0.1 lux illumination. When the Moon is viewed at high altitude at tropical latitudes, the illuminance can reach 0.26 lux. The full Moon is about 1,000,000 times fainter than the Sun.
Or, do you think that
all blue light comes from the Moon. That's even more ridiculous.
Either way, if you try to use sunglasses under only moonlight at night you will probably trip and may poke your eye out.
