Short answer: the “white” of the eye can look cloudy, red, yellow, brown, or blue for very different reasons. Dry eye and surface inflammation are common and often improve when the underlying cause is treated. A raised yellow spot may be a pinguecula, while a uniform yellow color in both eyes can signal jaundice. A new or changing brown or black spot needs a slit-lamp examination rather than a cosmetic whitening product.
Hello, I am Dr. Daniel Jinhag Baik, a board-certified ophthalmologist at Nunehim Eye Center on Siheung-daero in Guro-gu, Seoul. I regularly see office workers from Guro Digital Complex, Gasan Digital Complex, Geumcheon, Dongjak, Yeongdeungpo, Gwanak, Sillim, and Sindaebang who ask why their eyes no longer look as clear as they once did.
Key takeaway: before looking for a “whitening” drop, identify whether the change comes from the tear film, visible blood vessels, a localized conjunctival lesion, pigment, or a whole-body condition.
Why the eye can look less white
What we call the eye white is not one single layer. The sclera is the firm white coat. A transparent membrane called the conjunctiva covers it, and a thin tear film covers the outer surface. The appearance of the eye depends on the sclera, the transparency of the conjunctiva, surface blood vessels, pigment, and tear-film quality.
That is why an eye can look “yellow” or dull even when the sclera itself has not changed. Dryness, allergy, long screen hours, contact-lens irritation, dust, and inflammation can make vessels more visible and the surface less even.
1. Red or generally cloudy whites: dry eye and surface irritation
For people who work all day at a monitor in Guro or Gasan, an unstable tear film is a common explanation. When blinking decreases and tears evaporate quickly, the eye surface can become irritated. Small vessels in the conjunctiva then look more prominent.
Symptoms may include burning, a gritty feeling, fluctuating vision, light sensitivity, watering, and redness. Persistent redness is not simply a cosmetic issue; it can indicate dry eye, eyelid or meibomian-gland disease, allergy, or another source of inflammation.
Can it become clearer? Often, yes. Preservative-free or low-preservative lubricants, blink and screen habits, eyelid care, allergy treatment, and treatment for ocular-surface inflammation may reduce redness. This is not “bleaching” the eye. It is helping the surface return closer to its healthy baseline.

2. A yellow or yellow-white raised spot: pinguecula
A small yellow or yellow-white bump near the cornea—often on the nose side of the eye—may be a pinguecula. It is a common, usually benign change in the conjunctiva associated with age and repeated exposure to ultraviolet light, wind, and dust. It is not simply fat “stuck” on the eye.
A pinguecula can become red or irritated, especially when the tear film is poor. Lubricating drops, sunglasses with UV protection, and reducing dust and wind exposure can make the surrounding inflammation less noticeable. Drops do not dissolve an established pinguecula. Removal is considered only in selected cases, such as repeated inflammation, contact-lens interference, or substantial cosmetic concern, after a careful examination.
3. Both eyes look uniformly yellow: check for jaundice
A localized yellow spot is different from a relatively uniform yellow color across both eyes. Scleral icterus occurs when bilirubin in the blood rises. Liver disease, bile-duct problems, and increased breakdown of red blood cells are among the possible causes.
If the skin also looks yellow, urine is unusually dark, or the change appeared quickly, do not rely on a cosmetic eye drop. An internal-medicine assessment and blood tests may be needed. An eye examination can help distinguish a surface lesion from a systemic color change, but jaundice requires evaluation of the underlying medical cause.
4. A brown or black spot: usually benign, but change matters
Some people have a conjunctival nevus or other benign pigment from childhood or early adulthood. A spot that has been stable for years is often reassuring. However, a new spot in an adult, rapid growth, a change in color or shape, increasing thickness, or prominent feeder vessels should be examined.
At Nunehim Eye Center, a slit-lamp examination and baseline photography can help document a lesion. In selected cases, anterior-segment imaging or referral for further assessment may be appropriate. The goal is to identify the lesion accurately—not to remove pigment simply because it is visible.
5. Blue or gray whites: when the sclera looks thin
A blue-gray appearance can occur when a relatively thin sclera allows deeper tissue and vessels to show through. This is sometimes called blue sclera. It can be longstanding, but a new or marked change deserves assessment, especially when there are other health concerns such as unusual bruising, bone problems, or symptoms of iron deficiency.
What the color can suggest
| What you notice | Possible explanation | What to do |
|---|---|---|
| Red, burning, gritty, fluctuating vision | Dry eye, allergy, eyelid disease, or surface inflammation | Arrange an eye-surface assessment if persistent; avoid masking it daily with whitening drops. |
| One raised yellow-white spot | Pinguecula or another conjunctival lesion | Use UV protection and lubrication; examine it if inflamed, growing, or atypical. |
| Both eyes uniformly yellow, possibly with yellow skin | Jaundice or another systemic cause | Seek prompt medical evaluation and blood testing. |
| New, enlarging, or changing brown/black area | Pigmented conjunctival lesion | Book a slit-lamp examination and document change. |
| Blue-gray appearance | Thin sclera or a systemic/structural association | Arrange an ophthalmic assessment, especially if new. |
Can you make the eye white again?
If redness is driven by dry eye, allergy, or surface inflammation, the eye may look substantially clearer after treatment. A pinguecula or stable pigment spot will not disappear with artificial tears. Jaundice improves only when its medical cause is treated. The safest plan is therefore cause-directed care, not cosmetic whitening.
Why daily “redness relief” drops can backfire
Some decongestant drops temporarily constrict conjunctival vessels, so the eye looks whiter for a short time. Repeated use can lead to rebound redness when the effect wears off. If you feel you must use the drops every day to look normal, the underlying dry eye, allergy, inflammation, or medication issue should be checked instead.
Do not share eye drops, use someone else’s prescription, or continue a product that causes pain, blurred vision, or light sensitivity. Ask an eye doctor or pharmacist which lubricating option fits your situation.
What about cosmetic eye-whitening surgery?
Wide conjunctival excision performed only to make the eyes look whiter has been associated with serious delayed complications, including chronic conjunctival defects, scleral thinning, calcification, double vision, and necrotizing scleritis. The American Academy of Ophthalmology’s EyeWiki review describes a high complication burden in the largest reported series.
At Nunehim Eye Center, we prioritize identifying and treating the reason for redness or discoloration rather than removing healthy conjunctiva for appearance alone.
How we evaluate a change in the eye white
A typical visit includes a history of when the color changed, whether one or both eyes are affected, screen and contact-lens habits, medications, allergies, and general symptoms. A slit-lamp examination magnifies the conjunctiva, cornea, tear film, eyelids, and sclera. When useful, we add tear-film or surface staining tests, meibomian-gland assessment, and baseline photography for a pigmented or raised lesion.
If the pattern suggests jaundice or another systemic condition, we explain why medical testing outside the eye clinic is important. You can read our English guide to an eye exam in Seoul before your visit.
Questions patients ask
Will more artificial tears make my eyes white?
They may reduce redness when dryness is the cause, but they do not remove a pinguecula or a pigment lesion.
Does a yellow eye always mean liver disease?
No. A single yellow raised spot is often a pinguecula. Uniform yellowing of both eyes, especially with yellow skin or dark urine, needs medical evaluation.
Can a pinguecula disappear on its own?
An established pinguecula usually remains, although its irritation and surrounding redness can improve.
Should I worry about a brown spot?
Many are benign and stable. A new, enlarging, thickening, or changing spot should be examined and documented.
Is it safe to use whitening drops every day?
Daily vasoconstrictor use can cause rebound redness. Persistent redness deserves a cause-focused examination.
Why do my eyes look worse after a long workday?
Reduced blinking, evaporation, air conditioning, and screen-related strain can destabilize the tear film. Breaks, complete blinking, and appropriate lubrication may help, but ongoing symptoms should be assessed.
When is this urgent?
Seek prompt care for sudden vision loss or change, significant pain, marked light sensitivity, a new rapidly changing lesion, severe one-sided redness, or redness with nausea and headache. If both eyes and the skin turn yellow, arrange medical evaluation for jaundice.
