The pineal gland in the human brain possesses structures remarkably similar to those in our eyes. It also has strikingly similar faculties. This gland has cells that act as light receptors, as our retina has, and a structure comparable to the vitreous, the gel-like substance between the retina and lenses of our eyes. Something like a lens also exists in the pineal gland.
Scientists are still learning much about the pineal body. It has been known in both Eastern and Western belief systems as the seat of human consciousness. Eastern spiritualism holds that eyes exist all over the body in the form of apertures—acupuncture points. Western science is also coming to grasp that the pineal body is a kind of “third eye.”
For years, scientists recognized similarities between the pineal body and our eyes. In 1919, Frederick Tilney and Luther Fiske Warren wrote that said similarities prove the pineal gland was formed to be light-sensitive and possibly have other visual capabilities.
More recently, in 1995, Dr. Cheryl Craft, chair of the department of cell and neurobiology at the University of Southern California, wrote about what she called the “mind’s eye.”
“Under the skin in the skull of a lizard lies a light-responsive ‘third eye’ which is the … equivalent of the bone-encased, hormone-secreting pineal gland in the human brain. The human pineal is denied access to light directly, but like the lizard’s ‘third eye,’ it shows enhanced release of its hormone, melatonin, during the night,” she wrote. “The pineal gland is the ‘mind’s eye.’”
