What Does It Mean When Your Eyes Are Blue
What causes blue tint in whites of eyes? – The sclera is a thick connective tissue made up of different types of collagen and proteins. It works as a protective layer and extends from the cornea at the front of the eye, to the optic nerve at the back of the eye.

  • In a healthy eye, the sclera is white and smooth.
  • When a sclera has a bluish tint, it’s often caused by thinning of the sclera.
  • Thinness or transparency of scleral tissue makes the uvea, located beneath the sclera, and blood vessels more visible.
  • Essentially the blue tint in the white part of the eye is really the layers below the sclera peeking through the tissue.

Causes of scleral thinning often have to do with conditions that affect bone or connective tissue development. Other causes include anemia or similar iron deficiencies, certain medications, and exposure to silver compounds. SEE RELATED: Pinguecula: Causes, symptoms and treatment

What causes an eye to be blue?

The front layer of the iris (called the stroma ) can make eyes appear brown, blue or green –

For people with brown eyes, some of the cells also have brown pigment in them,

People with blue eyes have no pigment at all in this front layer, causing the fibers to scatter and absorb some of the longer wavelengths of light that come in. More blue light gets back out and the eyes appear to be blue. For people with green or hazel eyes, one or both of the layers of the iris contains light brown pigment. The light brown pigment interacts with the blue light and the eye can look green or speckled. Many people have variations in the color of their irises, often with one color near the pupil and another at the edge. This variation happens when different parts of the iris have different amounts of pigment in them.

Symptoms and Types of Heterochromia – Your iris gets its color from a pigment called melanin, It’s what makes them blue, green, brown, or hazel. Less melanin leads to lighter eye color. More melanin makes darker eyes. There are three types of heterochromia:

Complete heterochromia (heterochromia iridis) means one iris is a different color than the other. For example, you may have one blue eye and one brown eye.

Are blue eyes a problem?

5. Blue eyes come with a few risks – Melanin in the iris appears to help protect the back of the eye ( retina ) from damage caused by the UV radiation and high-energy visible blue light that comes from the sun and some artificial sources. Because blue eyes contain less melanin than most other eye colors, they may be more at risk of certain damage.

A higher risk of ocular uveal melanoma (a type of eye cancer ) A lower risk of developing cataracts No difference in the risk of developing age-related macular degeneration

Since many people with blue eye color are more sensitive to light and may have a higher risk of retinal damage from UV rays, eye doctors often recommend that people with blue eyes be a little more cautious about their exposure to sunlight. Eye damage from UV and blue light appears to be related to your lifetime exposure to these rays, so wearing sunglasses that block 100% UV (and most blue light) should start during childhood, when possible.
