Hi,
I don't believe this, but one 85 year old blind person says he has
faint seeing of "yellow" in his eye, after he was blind for lots of
years. Maybe he is lying or using a "Vitamin A, Vitamin E" medicine
whose name he is not telling me.
Now, if you have partial eyesight -------------- look in the dark with
your eyes open -------- that is common sense, you will strain to see
in the dark and force more blood into the eyes. Massage and breathing
exercises can also be recommended in the right directions. (See
