# The difference between flow types

## Prescription First

In the prescription-first type, consumers need to submit their own prescription information before they can select the lenses, this type supports adding conditions to the lens options, which can decide whether the lens is displayed to your consumer based on the user's prescription information. This type supports logic jumps. By default, consumers view lens steps based on their order in the flow. If logic jumps is turned on, consumers can view lens step based on what answers they choose and "jump" to specific step.

## Lens First

In the lens-first type, consumers need to select lenses before submitting their prescription information, this type does **not** supports adding conditions to the lens options. This type supports logic jumps.
