Does achromatopsia alone qualify for ssi?

My child was recently diagnosed with achromatopsia after having an erg performed. He is not legally blind since his vision is 20/100. He can see some moving objects for example we can play football he can see the ball to catch once its close to him but he can't play baseball because he doesn't see the ball until its too late. I didn't know if there are stipulations on the achromatopsia or if the diagnosis is enough to qualify him.
