I don’t need it to be night to realise that. I have -13 on both eyes, near-sightedness (not sure about the correct terminology in English). I see clearly for about one centimetre right by the tip of my nose, everything closer or further than that is a blurry and fuzzy mess. To use my phone without glasses I have to press it against my nose and can only see about half of the screen width clearly.

I think they just meant night time is when people remove glasses, so that’s when you notice the difference 😎
