There are specific stickers for this, shaped exactly to cover just the led. You can also get ones that let a bit of the light through, but not enough to blind
The one I used to use has a blue LED on the charging brick. I put it in the kitchen and started using the laptop charger in bed at night because of it. It's ridiculous.
Because blue LEDs were a monumental invention, and they felt the need to put that shit on everything for a while. A lot of newer stuff is amber or white LEDs.
I have seen similarly upsetting thing on Philips charger - green charging and red charged. Like wtf do you know how many times I pull it out half charged.
