Why are your eyes red after crying?
Reporting from hhmi.org, in section Ask a Scientist, Professor Jeremy Tuttle from the University of Virginia Health System , the neuroscience department explained, “When we cry, the fluid that forms tears comes from somewhere. Well, the tears come from the blood supply to the glands in the eye. When you cry, the blood vessels leading to the glands have to dilate themselves to provide fluid for the eye."
Tuttle added, when the eye is used only for seeing or in a normal state and not crying, the blood vessels that deliver oxygen and nutrients to the tissues will not be dilated so that they are almost invisible.
But when crying, the lacrimal glands, or tear glands, which are close to the eye, pump out secretions. These glands normally function to help keep moisture in your eyes.
However, when you cry, the blood vessels dilate because they are needed to remove more tears. That's why, your eyes will be red after crying.
There is really nothing to worry about if your eyes are red after crying because this is normal. This condition usually doesn't last too long.
One short-term way to deal with red eyes after crying is to use over-the-counter eye drops.
However, keep in mind that the habit of using eye drops too often to relieve eye redness after crying can be bad.
This is because the eye becomes dependent. After the effects of the eye drops wear off, your eyes may turn red or get worse. Try to stop using it and consult a doctor if necessary.

Causes of red eyes
Apart from crying, there are several possible causes of red eyes. Some of them are:
- Allergy, which may be caused by pet dander, dust or mold, and irritation from perfume and smoke.
- Dry eyesThe symptoms of dry eye include inconsistent tearing and drying too quickly. Sometimes even the tears can't come out at all.
- Rupture of blood vessels, but causes no pain. The blood vessels in the eye are small and when they burst, the blood becomes trapped and makes the whites of the eyes red.
Other causes of pink eye may also be due to glaucoma and contracting eye disease from other people. If you experience red eyes that are unnatural and maybe worrying, immediately consult a doctor for proper treatment.
