Can anything be done for "night blindness"?

Depends on the cause: If it is from a cause like cataracts, then surgery can be performed. It is due to a retinal condition like retinitis pigmentosa, then likely no. It is best to see an ophthalmologist who can determine the cause and make recommendations to treat.

Maybe: The most common cause of this is age related cataract. This happens to everyone that's over 35 and can cause night vision difficulty. The only fix for that is cataract surgery. One other cause is vitamin a deficiency and sometimes it's worth checking to make sure you are getting enough vitamin a.
