This could be a generational thing, as you stated. My grandma has several supersititons but nothing about lunar or solar eclipses. In the EE UU (US), it is simply said " do not look directly at it or you will become blind". That is all I have heard in my 33 years. Maybe older folks have heard of it.

No meaning in England.

After re-reading your question, I could have just said that generally speaking, in our country, there are no superstitions associated with a lunar eclipse :)

An eclipse of the Moon occurs when the Moon, during its lunar cycle around the Earth, moves through the shadow of the Earth caused by the Sun shining on the "daytime" side of our planet. Lunar eclipses occur far more frequently than solar eclipses (which are caused by the Moon moving between the Earth and the Sun, as we view it from our relative position). By definition, during a lunar eclipse, the Sun, Earth, and Moon must be directly aligned in that order. This occurs only during the Full Moon portion of the lunar cycle but will not occur during every Full Moon, due to slight variations in the Moon's orbital plane around the Earth.

I have never heard that about eclipse, that is interesting. I have heard that the lunar cycle can have an effect on the timing of you delivery, if there is a full moon near your due date you will most likely go into labor on the night of the full moon...I did! haha!
