They didn't know that bread mold was the natural source of penicillin, that foxglove was the natural source of digitalis, or that chemicals in those herbs can cause spontaneous abortions---they just knew that they worked.
Their remedies didn't come naturally. Remedies still don't come naturally even today. It takes countless trial and error and sometimes that doesn't work. The wisewomen knew that as well.
I have no doubt these wise women studied the eye and its functions and probably at one point could discern when someone was going to go blind versus an eye ailment they might be able to cure. They would, through their own research know which remedies could blind a person and which could cure.

It's not hard to determine where a Grimm's power comes from. He sees what others cannot. There's no need for a hexenbiest to come up with this special spell to disable a few extra cones and leave the rest untouched. All Adelind had to do was blind him.
Quote:I had surgery on both eyes Cataracts I see a Ophthalmologists once a year a couple years ago he add a test to map the whole back of the eye. How much the tests show I'm not sure but from with I see on the screen after the test looks like if he wanted to take the time he could count the rods and cones as they can enlarge any area.
I do know the mapping showed a condition that for years was known but wasn't able to see only a simple hand test would show it. The test was to check your peripheral you may have had it done the new test he uses does show the cause and how its progressing. Without the hand test well normally it was a card to the side of your head while you looked straight ahead the would move the card closer to the front and you were to say when you seen it. This is just for FYI should you ever need cataract surgery. Good note after the surgery I done have any restriction on my driver lic. any long.
I'm glad you brought up cataract surgery, js. My father just had both eyes done this past year and what I remember as being a day in the hospital surgery is now just a couple of hours. Within a week after having each eye done, he could see clearly and better than ever. I'm glad your surgery came out well. We have a whole host of pioneers to thank for their trials and errors and what it's led to.
A few years ago I encountered some severe floaters, and the doctor thought they were the forerunner of a detached retina, which can render a person blind. It is also in the retina where the rods and cones are located. The ophthalmologist did a scan of both eyes and thankfully no retinal detachment. Last year, during my eye exam, I had a scope done. The optometrist also showed me the back of the eye and the optic nerve. It was interesting. I never saw that before.
The best way to frustrate a cyberbully is to ignore him.
