I used to work in the optical industry, that's not what computer glasses are, they are just blue blocker lenses.

Any lens can be customized for desired focal length, including distance, intermediate (e.g. computer) or closeup/reading.

[bongodongobob]

Right. It's an industry term though and doesn't have anything to do with focal length.

Consumers develop their own interpretations and usage of industry terms used in marketing to consumers.
