Coma aberration and PALs
“Coma” aberration is generated by local power variation and exists therefore in all PALs
It gives an asymetric image in the shape of a comet
Impact of Coma’s is particularly important in FAR VISION, as the pupil diameter in Far Vision is bigger
Control of Coma guarantees an optimal visual acuity and better contrast in Far Vision.

Physiology: In presence of astigmatism the eye naturally focuses on vertical lines
All PALs generate some astigmatism around the meridian (power variation effect)
The eye accommodation is low
PALs should locate the vertical foci close to the retina
The axis of the residual astigmatism has to be vertical for the Intermediate Vision (+cyl)90°

Why ?How the « 5D » influence wavefront aberrations
Wavefront aberrations analyses for different eye-lens system configurations (different positions of the lens on front of the pupil)
The lens positioning in front of the pupil does influence
the value of the aberrations
the location of the areas of clear vision
All distance, intermediate and near zones are impacted
… but the most important impact is in the near zone
