The impairment you are referring to is commonly known as Achromatopsia, or the inability to see colour, only black and white.
There are several causes of the inability:
- One explanation is said to occur during foetal development within the Retinal Phototransduction Pathway. This results in the inability for the cones within our eyes to respond correctly. The cones are the parts of our eyes which respond to colour, therefore if they do not respond, only rods which respond to light and dark will be responding. This also links to reduced visibility in people with Achromatopsia as their sight is based primarily on light levels.
- Another explanation is based on damage to certain brain areas such as: the diencephalon, the cerebral cortex, the thalamus and areas within the brain stem. It can also be linked to tumors within the brain. This explanation relies more on damage to the brain rather than the actual cells within the eyes.
There is no treatment currently available to fully treat Achromatopsia.

What is the significance of the far point of a myopic eye in understanding vision impairment?
The far point of a myopic eye is the point at which objects appear blurry. Understanding this helps in diagnosing and managing vision impairment, as it indicates the eye's inability to focus on distant objects properly, leading to nearsightedness.
What color do color vision deficient people dream in?
Color vision deficient individuals can still dream in color, as color vision deficiency does not necessarily affect the ability to perceive colors in dreams. However, the colors perceived in dreams may vary depending on the individual's specific type of color vision deficiency.
What is the prognosis for visual impairment?
The prognosis for visual impairment varies depending on the underlying cause of the impairment. Some conditions may be reversible or manageable with treatment, while others may be permanent or progressive. Early diagnosis and intervention can greatly impact the prognosis for visual impairment. It's important to work closely with healthcare providers to determine the best course of action for managing visual impairment.
The cells responsible for color vision in mammalian eyes are called?
The cells responsible for the color vision in mammals are called as cones. I have been remembering the same by color vision by cones. That C and C. The brightness is perceived by rod cells. This is how you dispel the confusion. There are cones and rods to perceive the vision.

What is the Most Common Cause of Blindness in Nigeria?

How does Devic syndrome affect the eyes?
Devic syndrome is a chronic and degenerative disorder that usually affects both eyes. The eyes develop diminished sensitivity to bright lights, color vision impairment, and diminished light reflexes.
Do you go completely blind when diagnosed with Cone dystrophy?
Cone dystrophy does not typically lead to complete blindness, but it can cause significant vision impairment. This genetic condition affects the cone cells in the retina, which are responsible for color vision and visual acuity, leading to difficulties with bright light and color discrimination. The degree of vision loss varies among individuals, and some may retain some level of vision throughout their lives. Regular monitoring and supportive measures can help manage the condition.
Where can one have a color vision test?
One can have a color vision test on the 'Color Vision Testing' website which tests for color blindness. One can also have a similar test at their local opticians.
