What Causes Red Eyes?

Last updated 5 years ago

From acute angle-closure glaucoma to conjunctivitis, there are a number of causes of red eye. Although a major change in the color of a person’s sclera, or the white of the eye, may cause a patient to panic, it’s important to note that not all cases of red eye should be considered dangerous.

Some of the most common and treatable causes of red eye include allergies, bacterial infections, and viruses, such as pink eye. Pink eye symptoms are distinguishable from a bacterial infection because the latter is characterized by thicker drainage. As you will learn in this video, red eye caused by serious problems like corneal abrasion or acute angle-closure glaucoma needs to be examined immediately.

Treatment for this condition will always depend on its underlying cause, so it’s important to consult a medical professional. If you are experiencing red eye or another eye condition, call Wize Eyes of Long Island today at (415) 358-0040.
