I'm not an expert on color blindness, but from my limited research, the type of color blindness depicted in the movie cannot be corrected by lenses. The only lenses I've found merely enhance the signals from the color receptors. The total lack of functioning color receptors could not be fixed by lenses.
I still very much enjoyed the movie, and the cast did a fine job of depicting the emotions involved. While I appreciate making color blindness less of a mystery, it could have been more scientific, especially sine the main character is a science teacher.
The other minor point is that the color blind glasses I've found are tinted, while the movie showed clear lenses.
Still, I've given it a 9/10 rating.
