7. Pink Eye
Medically known as conjunctivitis, pink eye has a variety of causes, all of which can cause the eye to become red. It is an infection, typically caused by bacteria or viruses, but it may also result from allergens as well. Other symptoms include itchiness, watering, and an excess of eye crust and mucus, so much so that one may have difficulty opening their eyes in the morning after sleep. It is not a serious condition, but if it is left untreated and does not resolve on its own, it could create significant, vision-altering complications due to scarring of the eyes.
While generally only one eye is affected initially, it’s easy to spread to the other eye, or to other people via bacteria on pillows, towels, hands, and so on. Fortunately, only bacterial and viral pink eye is contagious; pink eye caused by allergies is typically harmless to other people. Because pink eye can come from multiple sources, it is a good idea to see a doctor to determine the best form of treatment. Generally, some types of pink eye will clear up on their own or with home remedies, but others will require medication, such as antibacterial eye drops.
There are several good reasons as it is not to overdo it when it comes to a night of drinking. Aside from the hangover you may wake up with the following morning, you may end up with eye redness in the course of the drinking itself. This is because the alcohol causes vasodilation, meaning that it makes the blood vessels in the eyes relax, and therefore, expand. Over time, however, frequent drinking will lead past vasodilation and cause vasoconstriction instead, shrinking the blood vessels. This effect can actually become permanent, leading to a condition known as spider veins.
Aside from the harmful effects of alcohol on the rest of the body, this particular cause of eye redness is not much to worry about; after all, it is primarily caused by excessive drinking. However, consider drinking less, and less often, and this likely will be less of a problem. Furthermore, you’ll be healthier overall, because you’ll be putting less strain on the kidneys and liver. When it comes to getting quick relief at the moment, consider over the counter eye drops, as these can help to clear up the redness. Oh, and drink more water; you’re going to need it.Related: 11 Liver Damage Signs You Can’t Ignore
This one probably comes as no surprise, as most of us have been here before. A lack of sleep can result in red eyes. In this case, the dilation of blood vessels comes as a result of oxygen. Specifically, the blood vessels expand in an attempt to get more oxygen to the eyes, because being sleep deprived limits the amount of oxygen that makes it to the eyes. Another thing that may redden the eyes is the lack of moisture- this is common among those who are sleep deprived, because the eyes are open longer, preventing remedial lubrication via shut-eye.
Fortunately, the solution, in this case, is simple. Getting more sleep will reduce the occurrence of red eyes. In the interim, one may rely on artificial tears as a moisturizing agent, or cold compresses. Sometimes, remedying a lack of sleep is as simple as changing bedtime habits (less light and electronic distractions in the hours winding down to bed, no eating heavy meals right before sleep). In other cases, it may be a result of other factors, such as depression, anxiety, or other disorders. If changing bedtime routines and other lifestyle factors don’t bring restful sleep, talk to your doctor.
