You’re deciding which clothes to wear, but wonder why their bright colors suddenly seem subdued. Or perhaps they look faded with your right eye but not your left eye.

Odd, right?

Not seeing colors the way you used to is often a symptom of optical problems, especially as we age. Let’s take a look at some of these diseases and explore ways a low vision eye doctor can help you improve or at least maximize your vision.

Cataracts occur when protein deposits accumulate on the eye’s crystalline lens and turn it opaque. Once-clear vision becomes cloudy and colors begin to fade.

The good news is that cataract surgery is a very safe procedure that replaces your cloudy lens with a new, clear lens. If you’ve had cataract surgery to restore clear vision, you’ll notice right away that colors appear much brighter than before. A few years after cataract surgery, some patients notice that colors may start to appear subdued. This is normal and can be treated very quickly using a laser procedure.

Glaucoma results from high pressure build-up inside the eye, which damages the optic nerve, reduces vision and can lead to blindness. Color-vision deficiency — the inability to tell certain colors apart — can be one of the signs that glaucoma is starting to affect the eyes.

The difficulty in distinguishing between blue and yellow colours is often associated with early glaucoma, whereas red-green deficiencies are generally associated with advanced glaucoma. However, there are times when it is difficult to measure or quantify acquired color vision deficiency, and color tests performed with standardized color test charts frequently characterize it as combined or nonspecific color vision deficiency.

Macular degeneration primarily affects older people by causing a deterioration of the macula, the center of the retina. This leads to blurriness and significant vision loss. Experiencing difficulty distinguishing between similar colors and hues is an early sign of the condition.

Optic neuritis occurs when the body’s immune system attacks the myelin coating on nerve fibers, causing blurriness and partial vision loss in one or both eyes. Colors, especially shades of red, become subdued, and it becomes harder to distinguish against a similarly colored background. Fortunately, the condition is usually temporary.

Diabetic retinopathy affects people with diabetes when high blood-sugar levels damage blood vessels in the retina. This causes these tiny blood vessels to swell, leak fluid, or close, and can even cause abnormal new blood vessels to grow. These new vessels are very fragile and prone to being damaged. Symptoms often include fading colors, blurriness, vision loss, and more.

If you notice that your color vision is reduced, you may be in the early stages of a range of eye diseases. It is important for any eye condition to be diagnosed and treated early on so it can be effectively treated.

If these eye diseases are not managed early, the color-related problems you’re experiencing could worsen, eventually affecting your vision permanently, resulting in what is known as low vision. Low vision indicates that your vision has deteriorated to a point which makes your everyday tasks challenging and can negatively impact your quality of life.

If you notice that colors are diminished or you are experiencing other worrying symptoms affecting your vision, immediately consult Dr. Richard Shuldiner. We will examine you by:

Dilating your pupils
Evaluating your visual acuity
Providing a visual field examination
Providing a colour vision assessment
Conducting eye pressure tests

The sooner we identify the underlying cause behind your reduced color vision, the sooner you will be able to start treatment to improve or maximize your vision.

Why are colors changing in my vision?

Color vision and macular degeneration When these cones are weakened or damaged, we see the wavelengths differently and cannot send correct signals to the brain. When the cones start to weaken because of disease, shades of yellow, purple, and pastels tend to be lost first because they have lower wavelengths.

What is deuteranopia?

Deuteranopia refers to red-green color blindness. This is the most common type of color vision deficiency, and it's usually genetic.

Why can't I see colors all of a sudden?

Some conditions that can cause color deficits are sickle cell anemia, diabetes, macular degeneration, Alzheimer's disease, multiple sclerosis, glaucoma, Parkinson's disease, chronic alcoholism and leukemia.

Why is Colour vision lacking in the dark?

The reason for this is our duplex retina. In bright light (above approx. 10 cd m⁻²), photopic vision based on three spectral types of cone photoreceptors allows colour vision, whereas in dim light (at intensities less than ≈10⁻² to 10⁻³ cd m⁻², see [1]), a single type of rod only allows colour-blind scotopic vision.
