Red eyes can result from a variety of causes, ranging from harmless to more serious conditions. Commonly, red eyes are caused by irritation or inflammation due to allergies, lack of sleep, or prolonged screen time. Environmental factors such as smoke, dust, or chlorine in swimming pools can also contribute to redness. Additionally, infections like conjunctivitis (pink eye) or blepharitis, and conditions such as dry eye syndrome, can lead to red eyes. In some cases, more serious issues such as glaucoma, uveitis, or a burst blood vessel may be responsible. It's important to pay attention to accompanying symptoms, such as pain, vision changes, or discharge, and seek medical advice if the redness persists or worsens, to ensure proper diagnosis and treatment.
Here are the top 5 most common causes of red eyes:
Allergies: Allergic reactions to pollen, pet dander, dust, or other irritants can cause red, itchy, and watery eyes.
Conjunctivitis (Pink Eye): This is an inflammation or infection of the conjunctiva, the transparent membrane lining the eyelid and covering the white part of the eyeball. It can be caused by bacteria, viruses, or allergens.
Dry Eyes: Insufficient tear production or poor-quality tears can lead to dry eyes, resulting in redness, irritation, and a gritty sensation.
Eye Strain: Prolonged use of digital screens or inadequate lighting can lead to eye strain and redness, often accompanied by discomfort and fatigue.
Contact Lens Wear: Improper use or extended wear of contact lenses can irritate the eyes, leading to redness and discomfort.
If red eye symptoms persist, it is important to seek professional medical advice to determine the underlying cause and appropriate treatment.
