Most people think of colorblindness as a condition present from birth, but it’s possible to develop changes in color vision later in life. While inherited colorblindness is more common, acquired color vision problems can occur as a result of health conditions, eye diseases, medications, or aging. Understanding the causes and when to seek help is important for maintaining your vision health.
 

What Is Colorblindness?

Colorblindness refers to difficulty distinguishing between certain colors, most commonly red and green, or blue and yellow. Inherited colorblindness is caused by genetic differences that affect the light-sensitive cells in the retina (the cones). This type of colorblindness usually remains stable throughout life.
 

Causes of Acquired Colorblindness

If you notice sudden or progressive changes in how you perceive colors, it may be a sign of an underlying issue. Some common causes include:
 

•          Eye diseases: Conditions such as glaucoma, age-related macular degeneration, and diabetic retinopathy can affect color perception.

•          Cataracts: The clouding of the eye’s lens can dull or shift colors, making them appear faded or yellowed.

•          Medications: Certain drugs, including those used to treat heart conditions, high blood pressure, infections, or mental health disorders, may cause changes in color vision as a side effect.

•          Neurological conditions: Disorders affecting the optic nerve or brain, such as multiple sclerosis or stroke, can alter how colors are processed.

•          Aging: Over time, natural changes in the eye may reduce the ability to perceive colors vividly.
 

When to See Your Eye Doctor

A sudden change in color vision is not normal and should be evaluated promptly. Since acquired colorblindness may indicate another health issue, scheduling a comprehensive eye exam is essential. Early detection can help protect your vision and overall health.

While inherited colorblindness is lifelong, developing color vision changes later in life is possible and may be linked to eye disease, medications, or other medical conditions. Paying attention to these changes and seeking professional care can help address the underlying cause and preserve your eye health.
