The best $4 I ever spent was on an eye patch. I use mine all the time,

adaptation -- in one eye, anyway.




Agreed. I too often enter the house with my observing eye covered with the
patch in an effort to protect my dark adapted "eye."

By the way, I seem to be "left eyed" when it comes to greater light
sensitivity, but observe using my right eye from years of habit.


Hmmm .. if you use a binoviewer ... No, guess you would be bumping into
things :-)
