Red Eye: Here’s what causes it, how to spot it and what you can do about it.
Redness in the eyes, also called bloodshot eyes, can be a cause for concern. If you have redness in only one eye, it may be nothing to worry about. On the other hand, some people experience the same degree of redness, pain and vision change in both eyes. This could indicate something more serious such as glaucoma, an inflammation of the optic nerve that leads to loss of vision.
