I had this exact same feeling whenever I wore glasses. Just suddenly feeling nerdy.

Then I got one of those round, cool-looking glasses that really go with the shape and my face, and it changed everything. I love wearing glasses now. (Btw. they are Ace and Tate, the European Warby parker.)

So, finding glasses that you absolutely love is crucial.

PS: I also have a nerdy pair for coding, they are weightless and super comfy for computer. Don't feel confident in them though.
