This is what convergence insufficiency looks like (thanks to the VisionHelp Blog):
People with convergence insufficiency may still see 20/20 when measured using a standard eye chart and basic vision screenings that are done in schools and pediatrician offices.
However, what the eye chart does not measure is how their eyes move and work together when doing work close up. That's why convergence insufficiency is so often missed - until a patients goes to a developmental optometrist.
