Color Blindness
Mild
Color blindness is a condition in which a person has difficulty distinguishing certain colors or perceiving colors in the usual way. The most common forms involve difficulty distinguishing red and green, while less common forms affect blue and yellow or cause very limited color vision. Color vision deficiency is often inherited, but it can also result from eye disease, neurological conditions, aging, or certain medicines.

When to Seek Medical Attention
Color blindness usually does not require urgent medical care. Seek prompt eye assessment if color vision changes suddenly, particularly when accompanied by blurred vision, eye pain, flashes, new floaters, or other changes in sight, because sudden changes may indicate another eye or neurological condition.

Overview
Color blindness is a condition in which a person has difficulty distinguishing certain colors or perceiving colors in the usual way. The most common forms involve difficulty distinguishing red and green, while less common forms affect blue and yellow or cause very limited color vision. Color vision deficiency is often inherited, but it can also result from eye disease, neurological conditions, aging, or certain medicines.

Causes
Inherited color vision deficiency usually results from genetic changes affecting the light-sensitive cone cells of the retina or the visual pathways that process color information. The condition may be present from birth and is more common in males for some inherited forms. Acquired color vision changes can result from retinal or optic-nerve disease, brain disorders, eye injury, aging, or certain medications.
Risk Factors
The main risk factor for inherited color blindness is a family history of color vision deficiency. Some inherited forms are associated with genes located on the X chromosome and therefore occur more frequently in males. Acquired color vision problems may be associated with aging, diabetes, eye disease, neurological disease, eye injury, or medicines that affect the retina or visual pathways.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Color blindness is diagnosed with color vision tests that require a person to identify or arrange colored patterns. Ishihara-type plates are commonly used to detect red-green color deficiency, while other tests can assess different types and severity of color vision loss. An eye examination may be recommended when color vision changes develop later in life or when an acquired eye or neurological disorder is suspected.
Prevention
Key Prevention Tips
Inherited color blindness cannot currently be prevented because it results from genetic factors
Acquired color vision changes may sometimes be reduced by preventing or treating underlying eye and neurological conditions and by avoiding unnecessary exposure to substances that can damage vision
Regular eye examinations can help detect other eye problems
People with known color vision deficiency can use labels, technology, and other visual aids when accurate color identification is important
Prevention Guidance

People with known color vision deficiency can use labels, technology, and other visual aids when accurate color identification is important.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
