So are his eyes solar cells, or “inter-dimensional apertures”?
In reference to the OP:
Why don’t they just show some degree of consistency in the comic books?
The following was taken from the “Official Handbook Of The Marvel Universe” (circa 1984) concerning just what Cyclops’ eye beams are:
*Known superhuman powers: Cyclops possesses the mutant ability to project a beam of concussive, ruby-colored force from his eyes. Cyclops’s eyes are no longer the complex organic jelly that utilizes the visible spectrum of light to see the world around it. Instead, they are inter-dimensional apertures between this universe and another, non-Einsteinium universe, where physical laws as we know them do not pertain. This non-Einsteinium universe is filled with particles that resemble photons, yet they interact with this universe’s particles by transferring kinetic energy in the form of gravitons (the particle of gravitation). These particles generate great, directional concussive force when they interact with the objects of this universe.
Cyclops’s mind has a particular psionic field that is attuned to the forces that maintain the apertures that have taken the place of his eyes. Because his mind’s psionic field envelops his body, it automatically shunts the other-dimensional particles back into their point of origin when they collide with his body. Thus, his body is protected from the effects of the particles, and even the thin membrane of his eyelids is sufficient to block the emission of energy. The synthetic ruby quartz crystal used to fashion the lenses of Cyclops’s eyeglasses and visor is resonant to his minds’ psionic field and is similarly protected.
The width of Cyclops’s eye-blast seems to be focused by his mind’s psionic field with the same autonomic function that regulated his oriinal eyes’ ability to focus. As Cyclops focuses, the size of the aperture changes and thus act as a valve to control the flow of particles and beam’s relative power. The height of Cyclops’s eye-blast is controlled by his visor’s adjustable slit. His narrowest beam, about the diameter of a pencil at a distance of 4 feet has a force of about 2 pounds per square inch. His broadest beam, about 90 feet across at a distance of 50 feet, has a force of about 10 pounds per square inch. His most powerful eye-blast is a beam 4 feet across which, at a distance of 50 feet, has a force of 500 pounds per square inch. The maximum angular measurement of Cyclops’s eye-blast is equivalent to a wide-angle 35mm camera lens field of view (90 degree measured diagonally, or the angle subtended by holding this magazine’s pages spread open, upright at 9.5 inches from your eyes). The minimum angular measurement is equivalent to the angle that the thickness of a pencil would subtend at 4 feet (3.5 degree, about a quarter of an inch viewed at 4 feet). The beam’s effective range is about 2,000 feet, at which point a 1-inch beam has spread out to 10 feet square, and then has a pressure of .38 pounds per square inch. Cyclops’s maximum force is sufficient to tip over a filled 5,000 gallon tank at a distance of 20 feet, or puncture a 1-inch carbon-steel plate at a distance of 2 feet.
The extra dimensional supply of energy for Cyclops’s eye-blast is practically infinite. Thus, so long as Cyclops’s psionic field is active (which is constantly), there is the potential to emit energy. The only limit to the eye-blast is the mental fatigue of focusing constantly. After about 15 minute of constant usage, the psionic field subsides and allows only a slight leakage of energy to pass through the aperture. Cyclops’s metabolism will recover sufficiently for him to continue in about an additional 15 minutes.
Special limitations: Due to a brain injury, Cyclops is unable to shut off his optic blasts at will and must therefore wear a visor or glasses with ruby quartz lenses that block the beams. *
I have entirely too much time on my hands.
