Many people assume colour blindness appears in childhood and stays constant for life. While true for some, a vibrant landscape can slowly fade into muted tones later in adulthood. Yes, adults can develop colour blindness.
Acquired colour vision changes happen gradually or suddenly and are often linked to health conditions, medications, or natural aging. Because these changes can indicate underlying health issues, paying attention to your vision can help an optometrist identify the root cause.
Why Acquired Colour Blindness is Different
Most people with colour blindness were born with it, and they’ve adapted to it their whole lives. Acquired colour blindness is a different experience. It can appear later in adulthood, and the symptoms can change as time goes on.
One of the biggest differences is that inherited colour blindness typically stays the same throughout life. Acquired colour blindness can improve or worsen depending on what’s causing it. Watch for any alterations in how you see everyday hues and book a comprehensive eye exam to stay ahead of these visual changes before they progress.
What Leads to Colour Blindness in Adults
Our eyes are complex machines, so many different conditions can affect them.
Eye Conditions That Affect Your Vision
Glaucoma, macular degeneration, and diabetic retinopathy can all affect parts of the visual system involved in colour, contrast, or detail. A bright red stop sign might lose its crisp edge if diabetes impacts your retinas. If you have diabetes, regular diabetic eye exams can help monitor your retina for early signs of trouble.
Systemic Health Concerns
Issues outside your eyes also play a role in your visual perception. Liver disease and neurological conditions can sometimes change how you perceive hues. A physical injury to the head or eye can also impact your colour perception long after the incident happens.
Medications That Affect Perception
Certain prescriptions can change how you see everyday objects. Drugs used to treat heart conditions, high blood pressure, or infections sometimes affect your perception. Tell your optometrist if you recently started a new medication and notice things looking a bit unusual.
Aging and Environmental Exposure
Getting older naturally impacts your eyes. After age 70, the lens can yellow slightly, which alters how blues appear. Exposure to industrial toxins like lead or carbon monoxide also impacts adult colour perception.
Signs Your Colour Vision May Have Changed
Colour vision changes don’t always feel dramatic. Sometimes it’s a slow shift that you barely notice until it affects your daily life. Watch out for these specific signs:
- Trouble telling apart reds, greens, blues, or yellows
- Colours seem duller or less vivid than you remember
- Difficulty distinguishing shades in low light
- Confusion with colours that used to look clearly different to you
If any of these sound familiar, it doesn’t automatically mean something serious is happening. A change in colour vision can be an early signal that something in your eye health deserves a closer look. A comprehensive eye disease assessment can help identify conditions such as glaucoma or macular degeneration that may be related to what you’re experiencing.
Can Acquired Colour Blindness Be Treated?
The most meaningful step is often identifying what’s behind the change in colour vision in the first place. If a health condition like diabetic retinopathy or glaucoma is involved, managing that condition may help slow further changes to colour vision. In some cases, adjusting a medication that’s affecting your vision can reduce or even reverse the symptoms.
This is why regular eye exams matter so much. Detecting the early signs of conditions like these gives you more options for managing them before they affect more of your vision.
Tools That Help Day-to-Day
Even when the underlying cause can’t be fully resolved, there are practical tools that can make daily life easier.
Some people benefit from contrast-enhancing lenses or other visual aids, depending on the cause of their colour vision changes. Glasses with glare-reducing lenses can also enhance colour contrast, especially outdoors.
Colour-identifier apps on smartphones are another helpful option. They can identify colours in real time using your phone’s camera, which can make tasks like choosing clothing or reading colour-coded labels much more manageable.
