Darcy velocity distribution (m/s) on an axisymmetric cross-section through the eye predicted by the model (scale m).

Notes: (i) arrow plot is normalise to one, so arrows only show flow direction, not the velocity magnitude and (ii) velocity magnitudes are indicated by the colour scale and (ii) velocity magnitudes larger than 5.0×10−7 (m/s) are not shown for clarity (these velocities occur in a small region where the flow paths become restricted between iris and lens).
