Subject: [Avodah] Monetary Damages?
From R? A Lichtenstein: Thus, they have also said: ?He who chops down his
plants, even though he is not permitted etc?? Also, the entire discourse
about he who tells another] ?Tear my cloak, break my vessel or my hand or
my leg? (BK 92a) deals only with the liability to pay or the lack of it.
However, it is certainly prohibited and the permission of one?s fellow is
of no avail with regard to this.
ME IIRC there?s a tshuva concerning jousting (Purim?) that holds one not
liable for damages due to implied consent. Does this imply that the
jousting itself is really prohibited?

Subject: [Avodah] Photogrey Glasses On Shabbos
From
https://ohr.edu/this_week/insights_into_halacha/5052
A story is told about Rebbetzin Leah Auerbach a?h, wife of Rav Ezriel
Auerbach shlit?a, whose doctor (ophthalmologist, perhaps) prescribed
photogrey glasses for her[1]<https://ohr.edu/5052#_edn1>. These
are glasses with photochromatic lenses, which darken when exposed to direct
sunlight, and become transparent when removed from the sunlight. The
doctor, attuned to religious sensitivities, explained to her that some
authorities feel that one should refrain from wearing them on Shabbos,
while others maintain that they are acceptable for Shabbos use. He
instructed her to ask her rabbi for a final halachic decision.
But to understand the halachic issues involved, a bit of background is
needed. Photochromatic lenses contain millions of molecules of silver
chloride or silver halide embedded in them. These molecules are transparent
to visible light in the absence of ultraviolet rays, which is normal for
artificial lighting. But, when exposed to ultraviolet (UV) rays, as in
direct sunlight, the molecules undergo a chemical process that causes them
to change shape and absorb portions of the visible light, causing the
lenses to darken.
The potential issue with wearing such lenses on Shabbos is that of
?Tzoveya?, Dyeing, one of the 39 Sabbath-prohibited categories of ?creative
labor? (melachos). It must be noted that our potential issue with photogrey
glasses cannot be considered part of the actual Biblical prohibition, as
that is exclusive to a type of dyeing that leaves a lasting effect
(miskayeim). Rather, it?s a potential Rabbinical prohibition of temporary
coloration, arguably similar to makeup application, which falls under this
prohibition.
