Ses yeux vs. les yeux

Question

I have trained myself to use les yeux, les bras, etc. when referring to body parts.  So why ses yeux in this context?  As you can see, this exercise precipitated lots of questions from me.  I really appreciate that you do these for us and they certainly generate a lot of thinking about word usage.  Thanks for the challenge!

Accepted Answer

If there's an other person involved and to make clear whose eyes you're talking about, the possessive pronoun is used in this case. Here's the corresponding lesson: https://french.kwiziq.com/revision/grammar/special-cases-when-you-can-use-mon-ma-mes-etc-with-parts-of-the-body-possessive-adjectives
