Austin's abilities. He elaborated, "When you're dealing with the area of fantasy, if you say, 'Well, they're bionic so they can do whatever they want,' then it gets out of hand, so you've got to have really, really tight rules. [Steve and Jaime] can jump up two stories but not three. They can jump down three stories but not four." Austin's superhuman enhancements are: A bionic left eye: It has a 20.2:1 zoom lens along with a night vision function (as well as the restoration of normal vision). The figure of 20.2:1 is taken from the faux computer graphics in the opening credits; the figure 20:1 is mentioned twice in the series, in the episode "Population: Zero" and "Secret of Bigfoot". Austin's bionic eye also has other features, such as an infrared filter used frequently to see in the dark and also to detect heat (as in the episode "The Pioneers"), and the ability to view humanoid beings moving too fast for a normal eye to see (as in the story arc "The Secret of Bigfoot"). One early episode shows the eye as a deadly accurate targeting device for his throwing arm. In Caidin's original novels, Austin's eye was depicted as simply a camera (which had to be physically removed after use) and Austin remained blind in the eye. Later, Austin gained the ability to shoot a laser from the eye. The Charlton Comics comic book spin-off from the series also established that Austin's bionic eye could shoot a laser beam (as demonstrated in the first issues of the color comic), but neither function was shown on television. Bionic legs: These allow him to run at tremendous speed and make great leaps. Austin's upper speed limit was never firmly established, although a speed of is commonly quoted since this figure is shown on a speed gauge during the opening credits. The highest speed ever shown in the series on a speed gauge is in "The Pal-Mir Escort"; however, the later revival films suggested that he could run approximately . A faster top speed is possible, as an episode of the Bionic Woman spin-off entitled "Winning Is Everything" shows female cyborg Jaime Sommers outrunning a race car going . In "Secret of Bigfoot" it is stated that he can leap high. In the later TV movies, Austin is shown leaping what clearly appears to be heights far in excess of this.
