Are 'half-glasses' the same as bifocals?

Not exactly. 'Half-glasses' primarily describes the physical frame (lenses only in the lower half). Bifocals are a lens type with two optical powers. A pair of half-glasses could contain bifocal lenses, but they could also contain single-vision reading lenses.

Can I use 'half-glasses' in everyday conversation?

It's understandable but uncommon. Most native speakers would use 'reading glasses' or simply 'glasses' in casual talk. 'Half-glasses' sounds more descriptive or technical.

Who famously wore half-glasses?

The style is often associated with Benjamin Franklin (hence 'Ben Franklin glasses' in AmE) and is a trope for scholars, judges, and meticulous clerks in historical fiction.

What is the main advantage of half-glasses?

They allow the wearer to read or do close work through the lenses, then look up and see the distance clearly over the top of the frames without having to remove them.
