When your eyes lack of water, they will get redness. When the red stuff is not absorbed by the corneal, it will be turned into yellow parts. However, if there is some problem for your liver, your eyes may turn yellow too. You'd better go to see the doctor and have a full check on the eyes to find the exact reason to cause your yellow eyes. Then you could accept the right treatment.
I have never heard of that dehydration will turn the eyes yellow before, though dehydration indeed cause decreased urine output and the urine is concentrated and deeply yellow. I think it is a sign of jaundice. In normal condition, the older red blood cells are replaced with the new ones in the body and the yellow pigment called bilirubin is processed by the liver and expelled from the body in the bile through the bile duct. But if the bile ducts are blocked due to pancreatitis or gallstones, or the liver does not function normally due to serious diseases such as cirrhosis, hepatitis, ischemic hepatocellular jaundice, liver cancer or pancreas cancer, the yellow eyes manifest. So you had better go to hospital for an overall examination.
well, yes, yellow eyes can be a sign of dehydration. we can say that dehydration can cause yellow eyes. First, you should know that dehydration has many symptoms, such as muscle cramps, nausea, heart palpitations, and lightheadedness. When you have dehydration, your eyes will stop making tears in extreme cases. In other words, it could cause the eyes to dry out. Of course, yellow eyes are also possible. To treat it, you should keep drinking more water. Also, you can mix water, orange juice, sugar, salt, and tea water together, and then drink them for a time. That can be very beneficial for your symptom. anyway, you can have a try.
