Last year, Jeffrey Tibbetts looked up at the moon and saw something he had never seen before: despite its being a crescent moon, most of it covered in the Earth’s shadow, the entire circumference was visible to him. “Oh god, it was really cool,” recalls Tibbetts, who cofounded the independent research organization Science for the Masses. Night after night, he could see all of the moon, regardless of what phase it was in. His daytime vision had also changed: sunrises were especially spectacular, almost neon in their brilliance. Kerry Grens, “Seeing Red,” The Scientist, February 2015, p. 22.
Here’s how to see the invisible:
- Avoid Vitamin A1 or retinol, which facilitates normal vision.
- Take Vitamin A2 or 3,4-dehydroretinal, which gives infrared sensitivity, instead.
- Take retinoic acid, a vitamin A derivative, for nonvisual processes including gene transcription.
Exercise caution – don’t try this at home because of possible side effects!

“…a crescent moon, most of it covered in the Earth’s shadow…” ?? The dark part of the moon, during a crescent moon, is not in the earth’s shadow. That would be an eclipse, which does not last “night after night.” The dark part of the moon, observed by Mr. Tibbetts, is the moon’s own shadow.
