The use of "era" or "fue" in this sentence depends on the context and the intended meaning.
If you want to convey that Marquitos was nearsighted at the age of 12 and wore glasses as a result, you can use "era" in the sentence:
"A los 12 años descubrieron que Marquitos era miope y le pusieron gafas."
Here, "era" is used to describe Marquitos' state of being nearsighted at that specific moment in the past.
On the other hand, if you want to emphasize that Marquitos used to be nearsighted at the age of 12 but may no longer be nearsighted, you can use "fue" in the sentence:
"A los 12 años descubrieron que Marquitos fue miope y le pusieron gafas."
In this case, "fue" indicates a past event or condition that might not be true anymore.
Remember that without further context, it is difficult to determine which tense is the most appropriate for this sentence.
