What is red blood in your eyes?

There are many reasons for red blood in the eyes. If the eyes show obvious red blood increase due to lack of rest and fatigue, it is normal to consider visual fatigue. If it is accompanied by increased secretions of different degrees, it is considered conjunctivitis, which may be caused by bacteria, viruses or chlamydia infection. If there is an increase in red blood near the periphery of the black eye, and at the same time, there is a fear of light, tears, blurred vision, it may be caused by keratitis, which may be related to infections such as bacteria, viruses, fungi, and acanthamoeba. If the eye is also accompanied by soreness and pain, it is found that the intraocular pressure is significantly increased, which may be caused by acute glaucoma. In addition, various eye traumas cause varying degrees of damage to the eyeball tissue, which can cause increased red blood, such as conjunctival laceration, corneal laceration, blunt ocular trauma, hyphema, etc.
