Browline glasses
When you say "glasses", it is plural. A "glass" is one of the lenses. "Glasses" would refer to both of the lenses, and a "pair of glasses" doesn't mention anything about the frame, but it mentions the two lenses. The frame is the object that joins the two lenses so you don't have to wear contacts and so it can stay on your head. When you say "a pair of glasses", you are referring to the "pair of lenses", not the frame. The frame holding the two lenses makes us think that it is one object, when the word "glasses" refers only to the lenses, not the frame. That is why it is called "a pair of glasses".

The defining colour in glasses means the colour used in the frame, as it is most visible. So the defining colour of nerd glasses means the same, the colour of the nerd glasses frame.

Yes but you get used to it
The Vocaloid Megpoid Gumi has glasses where the lens are red and the frame is a darker gray color.
The writing on the inside of the frame tells where it is made and by what company. If you get glasses from on Dr. it's probably the best to get the contacts from the same person.
