Follow this link to the story whose full title is Why light intensifies the pain of migraine even among the blind discovered.

The study looked at two groups.

Those in the first set were completely blind and were unable to sense light or see images.

The second group were legally blind which meant that although they were unable to see images they could detect the presence of light.

While the patients in the first group did not experience any worsening of their headaches from light exposure, the patients in the second group clearly described intensified pain when they were exposed to light, in particular blue or grey wavelengths,” said Prof Burstein.

They had me up until the grey wavelengths. But I jest.  The story is really worth reading if you are or were a migraine sufferer or know someone who is.  For many years, I used to suffer from these kinds of headaches.

I was going to post this story anyway, but when I saw Richard’s health related posts I knew I was on the right wavelength for the day.  (Originally accidental pun now intended.)
