Individuals with this deficiency, ie, it can not distinguish some colors, or, not sighted, are affected by color blindness. This genetic defect is linked to the portion of "non-homologous" between the X and Y chromosomes, the genes related to the production of proteins that express the vision of the pigmentation of green and red. It is an inherited trait that affects a greater number of males (about 8%) than females (0.5%). This failure to see or distinguish certain colors, can be connected to two colors or just one. Individuals may be colorblind: Achromatic: is the rarest form of color blindness, and individuals do not see any color. They see the world in shades of black and white. Dichromatic: individuals who have two types of cones instead of three. Are classified into: protan - disturbance to recognize the color red; deutan - disturbance to identify the color green and tritan - disorder that prevents the recognition of the color blue. Abnormal trichromatic: have all three types of cones, but realize the color tones changed. It is the most abundant form of color blindness.

Osobe s nedostatkom, odnosno, ne može razlučiti neke boje, odnosno, nije viđen, su pogođeni daltonizam. To je genetski poremećaj povezan s dijelom "non-homologna" između X i Y kromosomi, geni se odnose na proizvodnju proteina koji izražavaju viziju pigmentacije zelene i crvene. To je naslijeđena osobina koja utječe na veći broj muškaraca (oko 8%) nego žena (0,5%). Ovaj neuspjeh da se vidi ili razlikovanje određene boje, mogu biti povezani s dvije boje ili samo jedan. Pojedinci mogu biti colorblind: Achromatic: je najrjeđi oblik daltonizam, a pojedinci ne vidim nikakvu boju. Oni vide svijet u nijansama crne i bijele. Dvobojan: pojedinci koji imaju dvije vrste kukova, umjesto tri. Razvrstavaju se u: Protan - poremećaj prepoznavanja boja crvena, deutan - Poremećaj identificirati zelenu boju i Tritan - poremećaj koji sprječava priznavanje plava boja. Abnormalna trobojni: imati sve tri vrste kukova, ali shvatite tonovi boja promijenila. To je najrasprostranjeniji oblik daltonizam.
