According to the influencer, the weight is 100 g. I have 25 g (+lenses) glasses I wear often, and even that is right on the upper edge of what's comfortable and needs almost-uncomfortable tight arms to stay steady when my head moves.

Either those Meta glasses are clamping uncomfortably hard on the sides of your head all the time or they'll fall off the first time you lean forward.
