"Když jsem otevřel oči, můj pokoj byl prázdný."

[HenriqueMa402882]

I wrote "When I opened the eyes, my bedroom was empty" as it was bot mentioned any possessive term for the word "eyes". Is it really incorrect?

If you can use a possessive pronoun in English, do it. English always prefers possessives over articles. One would never say "the eyes" about your own eyes. At the same time, Czech is only using possessives when completely necessary.
