How has Gordon Freeman not broken/lost his glasses yet?

[Redem]

They are the source of his power

 

[Ajera]

They probably got infused onto his face when he first opened the portal and let all the aliens in.

 

[Novacain4862]

His eyes are mini gravity guns

 

[Holyeskimo]

that is all

 

[penguindude42]

Maybe they're like Magic Pants?

I always assumed he probably just wore the suits helmet. Seems kinda dumb to have that fancy suit than have your nice squishy head all exposed.

 

[Argtee]

They aren't actually glasses, they're a part of his face.

Hah! Now you finally know!

 

[FalloutJack]

They are part of his biology.

Psh. They're just for show. When he first woke up on that train he had already lost em. It was contacts from then on. He only puts on the glasses to look sophisticated in conversation.
