The white of the eye turns grey mainly due to aging, calcium deposits, or underlying health conditions affecting the sclera.
Understanding The White Of The Eye
The white part of your eye is called the sclera. It’s a tough, protective outer layer that keeps the eyeball’s shape and shields it from injury. Normally, the sclera appears bright white, which indicates good health. But sometimes, it can change color and develop a greyish tint. This shift in color can be subtle or quite noticeable, and it often raises concerns about what might be going on inside the eye or body.
The sclera’s appearance can tell us a lot about overall eye health. When it turns grey, it’s usually a sign that something is altering its structure or composition. This change isn’t just cosmetic; it can indicate deeper issues ranging from natural aging to serious medical conditions.
What Causes The White Of The Eye To Turn Grey?
Several factors can cause the white of the eye to take on a grey hue. These causes vary widely in severity and origin but generally fall into three categories: natural aging changes, deposits accumulating in the eye tissues, and systemic health problems affecting the sclera.
Aging And Natural Changes
One of the most common reasons for grey discoloration is simply getting older. As people age, their sclera naturally thins out and becomes less opaque. This thinning allows underlying tissues—such as the blue-colored uvea—to show through more easily. The result is a bluish-grey tint on what used to be pure white.
This effect is more noticeable in some people than others, depending on genetics and environmental factors like sun exposure. While aging-related changes are generally harmless, they still alter how the eyes look and may cause concern if not understood properly.
Calcium Deposits And Scleral Plaques
Calcium buildup in the sclera can cause distinct grey patches known as scleral plaques. These plaques form when calcium salts deposit in specific areas of the sclera, usually near where muscles attach to the eyeball.
Scleral plaques appear as flat, oval-shaped grey spots and are mostly seen in older adults. They’re harmless and don’t affect vision but do change the eye’s appearance considerably.
The exact reason calcium deposits form isn’t fully understood but may be linked to:
- Aging processes
- Minor injuries or inflammation
- Local tissue degeneration
Chronic Inflammation And Eye Diseases
Certain inflammatory conditions targeting the eye can cause changes in scleral color. Chronic inflammation leads to tissue damage and scarring that may give rise to grey or bluish discoloration.
Examples include:
- Scleritis: A painful inflammation of the sclera often linked with autoimmune diseases like rheumatoid arthritis.
- Episcleritis: A milder inflammation affecting just above the sclera.
- Scleromalacia perforans: A rare condition causing thinning and softening of the sclera.
These diseases not only change color but also cause discomfort, redness, and sometimes vision problems if untreated.
Systemic Conditions Affecting Scleral Color
Some systemic illnesses influence how your eyes look by changing scleral pigmentation or thickness. For instance:
- Osteogenesis imperfecta: A genetic disorder causing fragile bones also thins out collagen in eyes, producing a blue-grey tint.
- Ehlers-Danlos syndrome: Connective tissue disorder leading to fragile skin and eyes with visible underlying tissues.
- Liver disease: Can cause yellowing (jaundice) but sometimes affects overall eye coloration including subtle greying.
These conditions often have other symptoms beyond eye changes but may present initially with unusual eye appearance.
Sun Exposure And UV Damage
Ultraviolet (UV) rays from sunlight damage collagen fibers within the sclera. Over years of exposure without protection like sunglasses, this damage accumulates causing thinning and discoloration that looks greyish or bluish.
Sunglasses with UV protection help slow this process significantly by shielding delicate eye tissues from harmful rays.
Tobacco Use And Pollution
Smoking introduces toxins into blood vessels supplying the eyes which may promote oxidative stress and tissue breakdown around the sclera. Similarly, air pollution contains particles that increase inflammation within ocular tissues over time.
Both these factors worsen age-related changes making grey discoloration appear sooner or more pronounced than expected for one’s age group.
Surgical And Traumatic Causes Of Grey Sclera
Physical trauma or surgical procedures around the eye can alter its appearance dramatically:
- Eye surgeries: Certain surgeries involving removal or manipulation of conjunctiva (the thin membrane covering white eyes) might expose deeper layers creating a greyish look temporarily or permanently.
- Injuries: Blunt force trauma causing bruising beneath thin scleral layers can create a temporary gray-blue tint until healing completes.
These causes are usually accompanied by pain or other visible signs like swelling making diagnosis straightforward.
Differentiating Grey Sclera From Other Discolorations
Not all discolorations mean grey sclera specifically; some other colors might confuse things:
| Scleral Color | POSSIBLE CAUSES | Description/Notes |
|---|---|---|
| Grey/Blue Tint | Aging thinning, Osteogenesis imperfecta, Calcium deposits | Tissue thinning reveals underlying uveal tissue; common with certain genetic disorders. |
| Yellow Tint (Jaundice) | Liver dysfunction (e.g., hepatitis), Bilirubin buildup | Sclera turns yellow due to excess bilirubin; requires urgent medical evaluation. |
| Redness/Inflammation | Scleritis, Conjunctivitis | Blood vessel dilation causes red appearance; often painful or itchy. |
| Bluish Discoloration | Ehlers-Danlos syndrome, Thin conjunctiva | Bluish hue due to thin connective tissues showing dark underlying structures. |
| Darker Brown/Black Spots | Moles/nevi on conjunctiva | Pigmented lesions that should be monitored for changes indicating malignancy risk. |
Understanding these differences helps target appropriate treatments rather than guessing based on color alone.
Treatment Options For Grey Sclera Conditions
Treatment depends heavily on what exactly causes your grey-tinged white eyes:
- If aging-related thinning is responsible – no treatment is needed as this is normal.
- Scleral plaques from calcium deposits typically require no intervention unless they cause discomfort; artificial tears may ease dryness associated with plaques.
- If inflammation like scleritis is diagnosed – corticosteroids or immunosuppressive drugs prescribed by an ophthalmologist reduce swelling and prevent damage.
- Treating systemic diseases such as osteogenesis imperfecta involves managing overall health rather than direct eye treatment but regular monitoring by specialists remains crucial.
- Lifestyle adjustments like wearing UV-protective eyewear and quitting smoking help prevent worsening discoloration over time.
Early diagnosis ensures better outcomes especially if an underlying disease triggers these changes rather than normal aging alone.
The Importance Of Regular Eye Examinations
Regular visits to an eye doctor allow early detection of any abnormal changes including those affecting scleral color. Doctors use slit lamps and imaging tools to examine every layer of your eyes closely.
If you notice any new greying of your whites along with symptoms such as pain, vision changes, redness lasting longer than usual, seek medical advice promptly rather than ignoring them as harmless cosmetic issues.
Early intervention prevents complications such as vision loss associated with some inflammatory diseases affecting the sclera.

Frequently Asked Questions
What Causes The White Of The Eye To Turn Grey With Aging?
The white of the eye turns grey mainly due to natural aging. As the sclera thins over time, underlying tissues like the blue uvea become more visible, giving a bluish-grey tint. This change is harmless but can be more noticeable depending on genetics and sun exposure.
How Do Calcium Deposits Cause The White Of The Eye To Turn Grey?
Calcium deposits, known as scleral plaques, can form grey patches on the white of the eye. These flat, oval-shaped spots usually appear near muscle attachments and are common in older adults. While they alter appearance, scleral plaques are generally harmless and do not affect vision.
Can Inflammation Cause The White Of The Eye To Turn Grey?
Chronic inflammation or certain eye diseases can lead to changes in the sclera, causing it to turn grey. Inflammatory conditions may alter the tissue structure or lead to deposits that affect color. These changes can signal underlying health issues requiring medical attention.
Are There Underlying Health Conditions That Cause The White Of The Eye To Turn Grey?
Yes, systemic health problems affecting the sclera can cause grey discoloration of the eye’s white part. Conditions such as autoimmune diseases or metabolic disorders may impact scleral health, leading to color changes that reflect deeper medical concerns.
Is The Grey Color On The White Of The Eye Always A Sign Of Disease?
No, a grey tint on the white of the eye is not always a sign of disease. It can result from normal aging or harmless calcium deposits. However, if accompanied by other symptoms or sudden changes, it’s important to consult an eye care professional for evaluation.
Conclusion – What Causes The White Of The Eye To Turn Grey?
The white of your eye turning grey isn’t always alarming but definitely worth attention. Aging remains a leading cause due to natural thinning of protective layers revealing deeper tissues beneath giving off that bluish-grey hue. Calcium deposits forming plaques also contribute commonly without serious consequences.
