Is 2.0 eyesight bad?

Nearsightedness Severity Levels

The American Optometric Association (AOA) classifies nearsightedness into different categories based on prescription strength. If your eyesight measurement falls between -0.25 and -2.00, it indicates mild nearsightedness. For those whose numbers range from -2.25 to -5.00, they are categorized as having moderate nearsightedness.
