Why Is There Blue Around My Brown Eyes?
– Blue rings around the iris are caused by cholesterol deposits in the eye. The deposits are actually white or yellowish but can appear blue. This might sound dangerous, but it isn’t. Researchers estimate that this condition impacts anywhere between 20 and 35 percent of people, becoming increasingly likely as you age.
Why is the outside of my eye turning blue?
Sclera: Definition, Anatomy & Function The sclera, or white of the eye, is strong tissue that wraps around the eyeball. It helps maintain your eyeball’s shape and protects it from injury. Several things can make the entire sclera change color or cause spots of color. Many scleral conditions resolve on their own in a few weeks, but some require medical attention. The sclera wraps around the eyeball. The sclera, or white of the eye, is a protective covering that wraps over most of the eyeball. It extends from the in the front to the optic nerve in the back. This strong layer of tissue, which is no more than a millimeter thick, gives your eyeball its white color.
- It also protects and supports your eye.
- The plural for sclera is sclerae.
- The sclera functions as the supporting wall of the eyeball.
- It helps maintain your eyeball’s shape, and protects it from injury.
- The sclera is covered by conjunctiva, which are clear mucus membranes that lubricate (moisturize) your eye.
Muscles attached to the sclera help move your eyeball up and down and side to side. The sclera is made of tough collagen fibers, which crisscross in random directions. That random pattern gives your eyeball its white color and gives the sclera strength.
Episclera, clear, thin tissue resting on top of the whites of your eyeballs. Stroma, made up of fibroblasts and collagen fibers, blending into the episclera. Lamina fusca, a transitional layer between the sclera and the choroid and ciliary body outer layers. Endothelium, the basal, or innermost layer of the sclera.
Several things can cause the entire sclera to change color or spots of color to appear:
Blue sclera: If the sclera is thinner than normal, blood vessels may show through, giving your eyeballs a blue or gray hue. This may occur in people with certain health conditions. Examples include (a genetic bone disease) and (a disorder in connective tissue throughout the body). Other examples include iron deficiency and, Icteric sclera and jaundice: If the entire sclerae turn yellow, that could mean you have, Jaundice indicates liver disease, which means the liver isn’t filtering blood properly. Injury: If your eyeball is injured, it may have a bright red spot. This indicates a broken blood vessel that has leaked some blood. These red spots are usually harmless and go away in a few days or weeks. Irritation: If your eyes are “bloodshot,” you can see redness throughout the sclerae. Eyes may be irritated due to smoke, allergies, exhaustion or infection. Medication: Some medications can tint the sclerae blue or gray (for example, an antibiotic called minocycline). Melanosis: Your sclera may contain a flat, brown spot, almost like a freckle. This is more common in Black people. The spots are caused by high levels of pigment called melanin, and they’re harmless. Pinguecula: A small patch of yellow may bulge out from your sclera after damage from the sun, wind or dust. The patch may become inflamed and turn pink or red. Pterygium: If a pinguecula goes untreated, it can get larger, expand into the cornea and block vision. Primary acquired melanosis (PAM): If you have a flat brown spot on the eye that changes over time, this may indicate PAM. This condition can become cancerous, so report any new or changing spots on the sclera.
What is it called when you have a blue ring around your eyes?
A ring of white and blue–Arcus If you’re over the age of 50, you may have noticed a faint to moderate white/blue ring around your cornea. This is known as arcus and is a normal age-related finding. Arcus does not impact the clarity of your vision or the comfort of your eyes.
- It represents a gradual build-up of cholesterol.
- Patients over 50 years old with elevated cholesterol may be more likely to develop arcus, but those with arcus do not necessarily have elevated lipid levels.
- Essentially arcus is a routine finding that patients occasionally ask about.
- Due to the light color of arcus, patients with brown eyes are more easily able to detect this condition at home looking in a mirror.

Are dark circles attractive?
Am I the only one that finds dark circles kind of attractive? Most of them do find dark circles unattractive. most of us have it even though it is less visible and is overlooked without considering it as unattractive. But some have really dark ones which is either due to genetics, lack of sleep, or other skin problems.
Why do my eyes look bruised?
– Allergic shiners are caused by congestion in the nasal passages and sinuses. This congestion restricts blood drainage from these areas, causing small veins below the eyes to get wider and pool with blood. The swelling and excess blood is visible through the thin skin below the eyes and appears as dark circles.
Allergic rhinitis, also known as nasal allergy, is one of the most common causes of nasal congestion. Allergic reactions occur when the body’s immune system responds to a foreign body, such as pollen or pet dander. The immune system mistakenly treats these substances, which are known as allergens, as if they were harmful.
Common allergens, all of which can cause allergic shiners, include:
dust mitespet dandermold and funguspollencockroach feces
There are also many types of allergies to food, such as to dairy, eggs, nuts, or wheat. Furthermore, some environmental irritants can make nasal congestion and other allergy symptoms worse, such as:
air pollutionperfumes and other fragrancestobacco smoke
People with allergic conjunctivitis, which causes allergy symptoms that affect the eyes, are more likely to experience allergic shiners than others. Symptoms of allergic conjunctivitis include swelling, watering, itching, and redness of the eyes. Another risk factor for the development of allergic shiners is the time of year.
- People with seasonal allergies will probably notice that their symptoms are only present at a particular time of year, which may help them to pinpoint the allergen responsible.
- If allergy symptoms are worse in early spring, it suggests an allergy to tree pollen.
- Symptoms that appear in late spring and summer indicate a grass pollen allergy, while allergies during fall may be caused by a reaction to ragweed.
Indoor allergies, on the other hand, can occur year-round but may be worse in winter when there is less airflow through a home. Common indoor allergens include pet dander, mold, and dust mites. Allergic shiners can sometimes be caused by nasal congestion due to a sinus infection, cold, or flu, but this is less common than allergy causes.
Why are my eyes brown in the middle and blue on the outside?
Some people have two different colored irises from a condition called heterochromia. This condition is often caused by injury or trauma to the eye. Rarely, it may be caused by a birth defect such as Waardenburg syndrome, Sturge-Weber syndrome, congenital Horner’s syndrome, or Parry-Romberg syndrome.
