This is beautiful paper, submitted as part of the proceedings of the First European Asymmetry Symposium, held in Nice, France, on March 15–16, 2018, and which could have been untitled : « symmetry & photonics ». This is an extremely broad subject which could be covered by a full book. Very honestly the author decided to treat this subject, in his/her own way, at a double level : providing a very general background for a non-specialized audience, completed by a few, and of course really non-exhaustive, examples deeper presented for a more advanced/specialized audience.

Therefore the choice of the example is subjective and I fully respect the choice of the author. However he/she could have mentioned at least some current hot topics directly linked to “photon & symmetry” such as light carrying an orbital angular momentum (OAM) (see for instance Geneaux, R. et al. Synthesis and characterization of attosecond light vortices in the extreme ultraviolet. Nat Commun 7, 12583, doi:10.1038/ncomms12583 (2016) and reference therein) and super chiral light (see for instance Y. Tangand A. Cohen,  Enhanced Enantioselectivity in Excitation of Chiral Molecules by Superchiral Light, Science  Vol. 332, 333 (2011)). These are simple suggestions.

Otherwise the paper is very nicely written, presented and structured, for both the general background and the more advanced parts. So that I don’t have any specific queries for revisions (I could not even find a typo error !). The paper can be published as it is or (and this up to the author) with some mention at least of the two subjects I suggested above.

Report on the manuscript by G. Lippi "On asymmetries in optics: fundamental considerations and some current applications"

The author investigate the symmetry breaking induced by a single photon due to its chirality and explains how it can be transferred to daily live scales in lasers. The manuscript is written for the non-expert reader and explains in nicely expressed hand-waving arguments and relations to daily life examples the complex nature of photon-spin, symmetry breaking and quantum to classical scale.

I enjoyed reading the manuscript which is well written in the spirit of an non-expert reader (non physician). It nicely relates the complicated nature of photon spins and its symmetry breaking to something understandable to the audience addressed by this issue.
I think the manuscript is worthwhile publishing and I have just some detailed remarks, where especially the comments about figure changes are purely suggestion to the author.

Detailed remarks:

1) Abstract:
is presented as example -> is presented as an example
World -> world

2) chapter I:
advanced Reader -> advanced reader
are simply highlighted -> are highlighted

3) Chapter II:
I could not really make sense of the sentence:
This discretization is not exclusive to light, as the restriction
of electromagnetic radiation to the visible (for us) part of
the spectrum.

found in internet -> found in the internet

3) Chapter IIA:
of (electromagnetic) waves. -> of electromagnetic waves.

used up until now. -> used up until now.

Fig1: The rotating nature might be better visible if in the left figure the line is not ending on top of another one.

4) Chapter IIB:
and \omega is proportional to the frequency ->
and \omega=2\pi\nu is proportional to the frequency \nu

Fig.3: Maybe indicating incoming and outgoing photons by curly lines with its transporting m will be helpful.

5) Chapter IIC:
Fig 4: It might be helpful to indicated the oscillating nature of thelinear polarization by placing arrows --|<--->|-- (the | indicates the crossing of the circular and the linear polarized light)

very high-power interactions -> very high-intensity interactions
(might be better to reduce confusion about energy-frequency-power?)

6) Chapter IID:
remove (i.e., a 1 followed by 21 zeros) as this type of indications have been done already a few times.

7) Chapter IIIA:
construction. etc. Everyone -> construction, etc. Everyone

+1 photons . The -> +1 photons. The

lampbulbs -> lamp bulbs

through the balace in -> through the balance in

8) Chapter IV:
pressure, external signals and the like. -> pressure, external signals, and the like.
