You hear words like the heart is the window to your soul, or the gateway to an opened mind. Well, I do not know about that, but on thing I am certain about one thing, the eye can tell a lot about how you are doing and how healthy you are.

First and foremost, the white part of your eye, known as the sclera, should ideally remain white, indicating good health. However, when the entire sclera turns yellow, it's a sign of a condition called Scleral Icterus that should not be overlooked. This yellowing suggests an elevated level of bilirubin in the body. Normally, red blood cells have a lifespan of about 120 days or 4 months, after which they break down to produce bilirubin, which the liver processes.

Yellowing of the sclera can be attributed to either an accelerated breakdown of red blood cells or a malfunction in the liver's bilirubin processing. It might also be linked to a blockage in the bile duct. However, if tests for these issues yield negative results, it's possible that the patient is suffering from Gilbert syndrome, a genetic condition that causes bilirubin levels to rise due to factors like stress or dehydration.

Still on the Sclera, when a person has blue sclera it can be as a result of a genetic condition that affects the collagen of the sclera where it becomes very thin and it can be transparent allowing the ability to see through it down to the uvea. This condition is known as Ocular Manifestations of Osteogenesis Imperfecta.

Another sclera color that shows there is a problem with the body is when the sclera look red or pinkish. This is very common and it can be as a result of a viral cause, a bacterial cause, acute angle closure glaucoma, scleritis, birth blood vessel, anterior uveitis, inflammatory bowel disease, psoriatic arthritis, Ankylosing spondylitis, and so on. This diseases cannot be confirmed without testing. It will be completely wrong to just attribute pink eyes to any of them without properly checking. While it is very common, it can be very serious.

Additionally, the eyes play a crucial role in our vision. If you hold both index fingers up and focus on one, you should perceive the other as double; this is known as physiological diplopia. However, if someone cannot experience this double vision, it's an indication that one of their eyes might not be functioning correctly, with the brain suppressing it. Amblyopia is a common condition linked to this, and therapy can be undertaken to address it.

Let's take a look at Iris color. While we have distinct iris, our iris can either be light or brown. People with brown iris have a lower risk of melanoma of the uvea, lower risk of diabetic retinopathy, and macular degeneration, but have a high risk of cataract while people with light iris, are the opposite of this. While this is so, some people have two different eye colors known as heterochromia.

If people are born with it, then there is really nothing much that can be done, but when this begins to happen suddenly, then it can be as a result of eye injury, inflammation, Horner's syndrome, Ocular melanosis, and so on. People who special serums to grow their eye lashes have been said to have change in eye color as a result of prostaglandin present in the serum. People with Albinism also suffer from lack of eye color allowing for people to see the blood vessels inside the eyes through the iris.

To understand how important the eye is when telling about our health, lets look at the ring around the iris known as the kayser-fleischer ring and it is caused by a build up of copper in the body. This rings can be used to diagnose Wilson disease. With Wilson disease, the build up of copper in the eyes is used to identify it along with the build up of copper in the brain, and liver. When treatment is completed, the kayser-fleischer ring disappears.

The eyes offer a remarkable glimpse into our overall health and well-being. Changes in the color and appearance of the sclera, iris, and other eye structures can be valuable clues, telling us to about underlying health issues. Regular eye examinations are crucial not only for maintaining good vision but also for identifying early signs of systemic health conditions.
