Person who has a condition of monochromatism (total colour blindness). There are two types of monochromats: the cone monochromat whose photopic luminosity curve resembles the normal and who has normal visual acuity and dark adaptation; and the rod monochromat whose retina does not contain functional cones and, therefore, has poor vision, photophobia and sometimes …

Rod monochromacy; Total color blindness Definition Autosomal recessive, congenital retinal disease characterized by severely reduced or completely absent color vision, photophobia, nystagmus, reduced visual acuity, and nondetectable cone electroretinograms.
Rod Monochromacy ( Achromatopsia ), when all three of the cones are non-functional and therefore photopic vision (and therefore color vision) is disabled. Monochromacy of photopic vision is a symptom of both Cone Monochromacy and Rod Monochromacy, so these two conditions are typically referred to collectively as monochromacy. [1] [2]

In blue cone monochromatism, the blue cone and rod receptors are spared but the patient is missing the red and green cells. The patient has only rods and blue cone cells to function. These patients see some color in the blue spectrum. They may not see this as "blue" color but may see a blue colored object better than other colors.
Rod monochromatism (achromatopsia) is a congenital cone photoreceptor disorder, which is rare, affecting about 1 in 30,000 individuals. These patients have normal rod function but no detectable cone function; therefore, everything they see is in shades of gray (total color blindness). Is there a cure for rod Monochromacy?

Achromatopsia (rod monochromatism, color blindness) is a hereditary pathology in which the work of the cones – photoreceptors of the retina responsible for the perception of colors is disrupted. Complete achromatopsia is characterized by the loss of receptor function by all three types of cones – "blue", "red" and "green".
Blue cone monochromatism (BCM) is characterized by the absence of long-wavelength-sensitive (L) and medium-wavelength-sensitive (M) cone function in the retina. Thus, color discrimination is severely impaired from birth, and vision is derived from the remaining preserved short-wavelength-sensitive (S) cones and rod photoreceptors.
