Tritium sights don't spread green light. The green point is exactly that, just a fine point of green. The red tritium is the same. I have tritium sight pins on my bows as my first pin. Other "lighted" use a lens over a minute diode that's lighting up. The lens broadcasts a wide angle and will slough light at the edges of the lens itself and I think this is what you may thinking is occurring.
Try to imagine a green light being seen thru a black tube in an entirely black environment or better yet imagine a very small green laser beam...laser light doesn't spread outward and stays focused. That's what tritium does in a gun sight or a sight pin on a bow.
