Looking directly at the sun can damage the retina and/or cause blindness.
In theory, yes.
the moon twist twice as fast as the earth, but also travels 3 times as fast because it has to stay with earths forward motion. Im betting you didnt know that when the moon and the earth and sun line up evenly, it causes two different types of eclipses. A solar eclipse, and a lunar eclipse. when a solar eclipse happens, the moon is in the middle, when a lunar elipse is in effect, the earth is in the middle. you should never look excatly at a lunar eclpise because it can cause eye ball damage or even blindness. i hope you found my information usefull.

Insufficient information to answer question.
no it is not.
contagious? Unless blindness is the side-effect of a particular virus or infection, than no. Blindness is rarely contagious, did you maybe mean genetic, though?
yes ?
The infection is highly contagious in its early stages. Blindness results from recurrent untreated infections.
'Blindness' is a symptom of something else, and that something else may be contagious, but without specifying what caused the blindness, you can't say for sure. If a hamster had an accident and damaged its eyes, then that absolutely cannot be passed on to another hamster.
Although it is a disease it is not contagious. If you were in close contact with a person who had color blindness you would not catch the disease.
Moon blindness (snow blindness in horse terms) can be very severe. Look for swelling, redness, cloudiness, squinting, and constricted pupils in the dark. Also, the eye can have a blue or green tint. A tripping horse that is rubbing its eye, shaking its head, and running into things may also have moon blindness. You may think this isn't serious, but it is. After you've confirmed moon blindness, go to the vet immediately.
Moon blindness can also occur in horses with brown eyes. It is a very painfull infection of the iris [coloured part of eye]. It is not fully understood what causes it.
Colour blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women
Sudden acquired retinal degeneration, or S.A.R.D.S. is an eye disease that occurs in dogs, causing sudden blindness over a period of time ranging from hours to days. It is not contagious, although it's cause in unkown at this point.
this is an old wives tale. not a valid treatment. Dr. Rozen
