Many white spots on the eye are not harmful. Common causes include a small bump on the white of the eye linked to sun exposure, a gray or white ring at the edge of the clear front of the eye that comes with age, and tiny deposits inside the eyelid [1,3,4,13]. But a white spot on the clear front of the eye with pain or redness can be a serious infection, and a white pupil in a child needs an eye exam right away [9,17].
Netra Eye Institute is an acupuncture and Oriental medicine practice, not an eye doctor's office. This guide helps you decide where to go for care. It does not replace an eye exam.
In this article
The cause depends on where the spot sits. Use this table, then read the section that matches.
| Where the spot is | Common causes | How urgent? |
|---|---|---|
| White of the eye or the corner | Pinguecula, pterygium, concretions, cysts | Usually not urgent. Get it checked if it grows or changes. |
| Clear front of the eye (cornea) | Corneal ulcer, corneal scar, arcus, band keratopathy | Same day if there is pain, redness or blurry vision |
| Colored part (iris) | Arcus in front of the iris, Brushfield spots, rarely a tumor | Get any new or changing spot checked |
| Pupil | Cataract (adults); white pupil in a child | Right away for a child |
| In your vision, not on the eye | Floaters, white dot syndromes | Right away if sudden |
The white of the eye is covered by the conjunctiva, a clear, thin tissue [3].
Looks like: A small, raised, yellowish or gray-white bump near the cornea, most often on the side closest to the nose [1,2]. So it can look like a spot in the inner corner of the eye.
Who gets it: It is linked to sun (ultraviolet) light, wind, dust and age. Arc welding is a major job-related risk [1,2].
Harmful? Usually not. It is not cancer and does not affect vision [1,2]. When it gets red and swollen (pingueculitis), it may burn, itch or feel gritty [2].
Eye doctor's care: Usually just lubricating drops, sometimes mild steroid drops for a short time. Removal is rare, for comfort or looks. See your eye doctor if it changes in size, shape or color [1].
Looks like: Raised white tissue with visible blood vessels that can grow from the white of the eye onto the cornea [3].
Who gets it: People with a lot of sun and wind exposure, such as outdoor workers. It is rare in children [3].
Harmful? It is not cancer, and most cause no lasting problems. If it grows far onto the cornea, it can affect vision [3].
Eye doctor's care: Usually sunglasses and artificial tears, sometimes mild steroid drops. Surgery is an option if it blocks vision or for looks, but it can grow back. A yearly visit with an ophthalmologist is advised [3].
Concretions are tiny yellow or white specks, usually smaller than 1 mm, on the inner lining of the eyelid. They are more common after age 50 and with long-term surface inflammation. They are usually harmless. If one pokes through, it can feel like something is in your eye, and an eye care professional can remove it after numbing drops [4].
Cysts are fluid-filled bumps in the conjunctiva. They can follow inflammation, injury or eye surgery and may cause discomfort or tearing. Options include lubricating drops or removal [5].
Age-related scleral plaques are oval patches on the white of the eye, usually after age 70. They can look see-through or gray, or white if calcium builds up. They usually cause no symptoms and are not considered a health problem [6,7].
A growth that needs a closer look. Sometimes a surface growth is a precancer or cancer. One type looks white and thickened, much like a pinguecula or pterygium. A small tissue sample (biopsy) may be needed to tell [8]. This is why any spot that grows or changes should be checked [1].
The cornea is the clear outer layer at the very front of the eye [12].
Looks like: A white patch on the cornea, often with redness, pain, watering, light sensitivity, blurry vision or discharge. At first, it can look like pink eye [9].
Who gets it: Contact lens wearers have a higher risk, especially with soft lenses left in overnight. Injuries, scratches and very dry eyes are other causes [9]. Contact lens infections are the most common cause of keratitis (inflammation of the cornea) [12]. See our keratitis page.
Harmful? Yes. Without treatment, it can scar the cornea and cause severe vision loss [9]. In the worst cases, contact lens infections can lead to blindness or a corneal transplant [10].
Eye doctor's care: Drops matched to the cause. Before the cause is known, antibiotic drops that work against many bacteria may be used. Severe ulcers may need a corneal transplant [9].
A deeper scratch, injury or infection can leave a scar on the cornea, and a scar can cause vision problems [9,12]. If the damage cannot be repaired, doctors can replace the damaged part with healthy donor tissue. This is a corneal transplant [12].
Looks like: A gray or white ring or arc at the outer edge of the cornea, made of fat (lipid) deposits [13].
Who gets it: It becomes more common with age [13].
Harmful? It does not affect vision and needs no treatment. In men under 40, it has been linked to a higher risk of heart and blood vessel disease [13].
Eye doctor's care: If it shows up before age 50, a blood test for cholesterol and other blood fats is advised [13].
Looks like: A band of calcium deposits across the part of the cornea left open between the eyelids. The deposits get whiter and denser over time [14].
Who gets it: People with long-term eye problems, such as chronic inflammation inside the eye, dry eye or long-standing glaucoma, and people with conditions that raise blood calcium or phosphate, such as kidney failure [14].
Harmful? It can slowly blur vision and can cause pain [14].
Eye doctor's care: If it affects vision, comfort or looks, options include a calcium-binding solution with gentle scraping, or laser treatment [14].
The pupil is the black center of the eye [17]. Behind it is the lens, the clear part that helps focus light [19].
In adults: cataract. A cataract is a cloudy area in the lens. It is very common with age [19]. It forms slowly and does not hurt [20]. Vision gets cloudy, colors may fade, and glare can bother you [19,20]. A cataract can also make the pupil look white [17]. Early on, new glasses and brighter light can help. Surgery is the only way to get rid of a cataract, usually once it gets in the way of daily life [19]. See our cataract guide.
In children: a white pupil (leukocoria). A white pupil or white glow in a child needs prompt attention [17]. Causes include a cataract present from birth, retinoblastoma, Coats disease (a disease of the retina), a parasite infection called Toxocara, and inflammation inside the eye (uveitis) [17]. Retinoblastoma is most common before age 5 and can be cured when found and treated before it spreads outside the eye [18]. A cloudy cornea can look like a white pupil and also needs care right away [17].
It depends on the cause. A pinguecula usually grows slowly over years, and drops can calm it when irritated [1]. Arcus needs no treatment [13]. An infection needs prompt treatment to help prevent a scar [9]. A cataract can only be removed with surgery [19].
Common causes, such as a pinguecula or pterygium, are not cancer [1,3]. But some surface growths are precancer or cancer and can look similar [8]. See an eye doctor if a spot grows or changes in size, shape or color [1].
A pinguecula, pterygium or arcus is linked to sun, wind, aging or fat deposits, not to an infection [1,3,13]. Some eye infections do spread, such as viral and bacterial pink eye. If an infection is possible, wash your hands often and do not share towels, pillows, eye drops or eye makeup [25].
Yes. Contact lenses raise the risk of a corneal ulcer, especially soft lenses worn overnight [9]. Lens wear is also a risk factor for pinguecula [2]. Do not sleep in lenses unless your provider says to, keep them away from all water, and replace your case at least every three months [11].
It may be arcus in the cornea in front of the iris [13], or Brushfield spots [15]. Have any new or changing spot on the iris checked [16].
In adults, it can be a cataract [17]. In a child, a white pupil is not normal and needs an eye exam right away [17,18].
Lubricating drops ease irritation from a pinguecula or pterygium. When removal is needed, it is done with surgery [1,3]. Infections need prescription drops from a doctor who has examined your eye [9]. Do not use homeopathic or unapproved eye products [26].
Netra Eye Institute does not diagnose or treat white spots on the eye. Finding the cause and treating it is an eye doctor's job. Acupuncture, herbs and Netra Restoration Therapy (NRT) do not remove or treat any of the spots in this article.
Some people with a pinguecula or pterygium also have dry, gritty or burning eyes [2,3]. Dry eye care is one area where some people use integrative support alongside their eye doctor's plan, never in place of it. Our dry eye guide explains more. If you have a new white spot on your eye, see an eye doctor first.
