Red eyes from infections
Most people who get red eyes are due to inflammation on the eye’s surface. Here are some infectious causes of why you have red-eye :
- Conjunctivitis: it is produced by the inflammation of this membrane that covers the eyelid and the sclera since it is exposed to bacteria and irritants. There are two types of conjunctivitis, bacterial and allergic; some of the symptoms of conjunctivitis are increased tearing, sensitivity to light, red eyes, and itching.
- Blepharitis: it is an excess in the production of oils by the glands found in the eyelid and is very common in people who suffer from seborrheic dermatitis. Symptoms of this condition include burning the eyelids, forming scales that stick to the eyelashes, itching, and redness. Applying warm compresses and constantly cleaning the eyelid will treat this condition.
- Corneal ulcers: are caused by viruses, bacteria, fungi, or parasites, although they can also appear due to excessive dryness of the eye, inflammatory disorders, or that you have had a scratch or introduced a foreign object. Symptoms of this lesion are watery eyes, itching and discharge, sensitivity to light, and blurred vision. Eye drops are usually the treatment option to reduce inflammation. However, everything will depend on the cause of the ulcer.
- Uveitis: the uvea is the layer of the eye that provides blood flow to the retina; when it becomes inflamed, it is what we know as uveitis. This condition is usually associated with autoimmune disorders such as rheumatoid arthritis or an infection. Some of the symptoms are blurred vision, the sensation of flies flying in the picture, and sensitivity to light. Treatment will depend on the cause and may include oral steroids, eye drops, or antibiotics.
Red eyes from injuries
The most severe cases in which constant red eyes can occur are due to injuries to the ocular membrane; some of these are:
- Acute glaucoma: it is when the pressure in the eye suddenly increases, causing pain, nausea, vomiting, a sensation of inflammation in the eye, redness, and severe vision problems. It is considered a medical emergency since it can compromise vision; This condition occurs first in one eye and is very likely to happen.
- Corneal abrasions: these happen when an object can be from sand, dust, insects, sparks, scrapes, or cuts to the cornea, and in case it becomes infected, it can produce a corneal ulcer. This injury causes watery eyes, swollen eyelids, increased tears, and bloodshot eyes. It would help if you went to the doctor immediately for the treatment to help the wound heal.
Other less severe causes of why you have red eyes can be:
- Dry eyes: dry eyes are related to poor eye lubrication, either due to the low production of tears or insufficient quality tears, which generates symptoms such as itching and dryness, especially when you are in front of the computer or if you are in air-conditioned environments. In most cases, it is treated with artificial tears.
- Misuse of contact lenses: wearing contact lenses for too long, sleeping or bathing in the sea or swimming pools can cause infections, so you must follow the instructions for their correct use.
