7 Causes of Red Eyes You Need to Know

Redness in eyes, also sometimes called “bloodshot eyes,” indicates benign or critical issues that need medical treatment. If you are suffering from Beverly Hills red eyes, you should visit an optometrist to check your eye condition. But before that, you should know what causes red eyes. 

Here are the key causes of red eyes you should be aware of: 

  • Allergies

Seasonal/environmental allergies, such as cigarette smoke and pet dander, may cause red eyes. You may experience burning, itching, treating, and even non-eye symptoms. Treat the allergies with either OTC or prescribed antihistamines and eye drops, which lubricate your eye surface. 

  •  Dry Eyes

Glands above your eyes help protect and lubricate the eyes. You get dry eyes if you don’t produce sufficient tears if they are of poor quality. Dry eyes may cause redness, light sensitivity, and blurred vision. 

  • Subconjunctival Hemorrhage

When a blood vessel inside the eyes breaks, it leaks blood onto the eye surface, which causes red eyes. As the hemorrhage is usually benign, it resolves itself in a week. 

  • Conjunctivitis

The inflammation of the membrane covering the eyelid interiors and the eyes’ white element makes the whites look red/pink. Conjunctivitis can be the outcome of allergies and viral/bacterial infections. When the infection gets highly contagious, you need immediate medical attention. 

  • Blepharitis

Blepharitis is eyelid inflammation, which makes your eyes look swollen and red. It usually occurs when oil glands or bacteria in your eyelids are clogged. Blepharitis, if left untreated, can cause more critical symptoms, such as blurred vision, eyelash loss, or growth in the wrong area. 

  • Scleritis

Scleritis is the sclera inflammation, which is related to autoimmune diseases, such as lupus, rheumatoid arthritis, and Sjogren’s syndrome. It may also occur because of an eye injury or infection. 

  • Angle-Closure Glaucoma

Glaucoma consists of several disorders which cause eye pressure, damage to optic nerves, and vision loss. Angle-closure glaucoma is when you experience a quick increase in eye pressure that causes red eyes, headache, vomiting or nausea, halos surrounding objects, and extreme pain. Such a type of glaucoma is a medical disorder that needs immediate treatment to cure vision loss. 

The Takeaway

Now you know the most common causes of red eyes. Are you having red eyes but not sure if it gets critical? Visit an optometrist in Beverly Hills so they can evaluate and diagnose your eye condition to suggest the right treatment.
