Lynx is not a screen reader. (In fact, it's considerably less accessible to blind users than a typical desktop browser -- as a console application, it has no way to provide accessibility data to a screen reader.)
A screen reader is a tool like JAWS or VoiceOver which interacts with desktop software (including web browsers like Chrome or Safari) to provide information about what the user is interacting with.
