Accelerated Vision is the ability to perceive the world in slow motion while moving at super speed or standing still.

Many speedsters experience this (such as Lana Lang, Emily Dinsmore, Bart Allen, and even superpowered Kryptonians such as Zod and Clark), meaning this seems to be common among all speedsters.


This ability is first displayed in the second episode of the Smallville tv series, Metamorphosis, when Clark saves Jonathan from what could have been a fatal fall. According to the commentary of that very episode, this is referred to by the Smallville crew as "Clark time", which means each speedster has his or her own time.

Physical AppearanceEdit

When a speedster is in super speed mode, everything and everyone else around moves greatly slow. As he or she moves, he or she is followed by sonic colour images.

Powers and AbilitiesEdit

Solo timeEdit

Clark moving faster than the fire sees Lana.

When a speedster is operating at super speed, somehow he or she is able to see the world as it would normally be seen except moving very slow or not at all.

Clark and Lana can both see the world in slow motion even while standing still, as seen in (Power). Clark also triggered "Clark time" when he dodged a bullet for the first time and when he was shot at by Lex. This suggests that this ability can only be achieved through concentration.

Shared timeEdit

Lana and Clark sees each other while moving at superspeed.

When two speedsters are both moving at super speed, they can share time together; this means that they are able to perceive one-another's super fast movements while the rest of the world appears as if it is moving slowly or not at all. Clark has shared "Clark time" with Lana on a large number of occasions and vise versa. During encounters with Bart Allen, it is shown that if one speedster is faster than another, it may be difficult for the slower speedster to track their movements (Accelerate, Run).


There are two instances that imply that "activating" this ability requires some amount of concentration, and is therefore not an automatic effect for speedsters. The first time was when solar flares were messing with Clark's powers in (Perry), and the second was when he had lost his memory and did not have any control over his speed (Blank).
