Is the word óculos the same in Brazilian and European Portuguese?

Yes

The word "óculos" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. It is a masculine plural noun used to refer to eyeglasses or sunglasses. The only difference lies in pronunciation:

• Brazilian Portuguese: The vowels tend to be more open, and the rhythm of the word is more "syllable-timed," meaning each syllable is given relatively equal weight. The unstressed "u" is pronounced clearly as /u/.
• Continental Portuguese: The pronunciation is more "stress-timed," meaning unstressed vowels are often reduced, shortened, or even swallowed. The "u" might be very subtle, and the overall cadence is more clipped.
