In this sentence from the lesson, why isn't the first verb in the imparfait?

Question

Depuis que j'ai quatre ans, je porte des lunettes. (The speaker is no longer 4 yrs old)

Accepted Answer

Bonjour Katie !

I understand your confusion here, but in French, when saying "Since I was 4, young, small....", you will use Le Présent instead of l'Imparfait!
E.g.
Depuis que j'ai 4 ans
Depuis que je suis jeune
Depuis que je suis petit(e) ...

I think here it is because the action described as starting when you were small is still ongoing when you're speaking.

I hope that's helpful!
À bientôt !

Answer

I thought that might be the case -- the fact that the action is continuing in the present. Thank you so much for the clarification.
