Our eyes are important but fragile organs that allow us to see the world around us. As sight is the strongest sense for most people, it is of critical importance that we take care of our eyes and investigate any changes in eyesight, and the appearance of the eyes themselves. The occurrence of red eyes, for example, may result from many causes, some of which are serious, and others that are not. If you have red eyes, you’ll want to take the time to find the cause of them, and, if necessary, get appropriate medical treatment as soon as possible.
What Causes Red Eyes?
While there are a number of different causes for red eyes, the actual redness is a direct result of the expansion of blood vessels. If you look closely at the white of a healthy eye, you will see tiny red lines, which are blood vessels, all over it. When these blood vessels become inflamed, they expand to take up more space, which in turn gives the eyes a red appearance. The actual dilation of blood vessels in the eyes itself can come from a number of conditions, which may be determined by other symptoms, such as itchiness or soreness, etc.
As mentioned earlier, some of the conditions that lead to red eyes are serious and require a diagnosis and medical attention to prevent severe, permanent damage to eyes and vision, or other aspects of health. Other conditions are less serious, but may still benefit from medical attention. That being said, there are also those conditions that are simple enough that they can be handled at home with no medical intervention. Continue on for some of the most common causes of red eyes, so you can assess the situation. However, if you are unsure, it’s best to consult a medical professional.
Allergies can have a number of effects on the body, including the eyes. Essentially, an allergic reaction is the activation of the immune system to a threat that is actually harmless. This causes symptoms such as redness and inflammation, effects that help control the spread of illness or infection… except there’s no infection in the case of allergies. Generally, pollen, pet dander, and dust work as allergens for those who have allergies. Such allergens can cause the eyes to become itchy, watery, and irritated, symptoms that will only grow worse if one rubs at their eyes in response to irritation.
Generally, if the allergen is removed, and the area is no longer overstimulated by scratching or rubbing, the redness will recede. This, however, can be difficult if the area is filled with allergens, such as a field of flowers or a dusty room. Cool water and compresses can speed up the recovery time, to a degree. Otherwise, there are eyedrops specifically designed to clear up allergens, along with antihistamine medications. That said, because of over the counter remedies for eye and sinus allergies, allergies are not normally a serious problem for most people, and medical attention is usually not needed.
