Red eye is a condition where the white of the eye (sclera) appears red or pink due to irritation, inflammation, or blood vessel dilation. It can be caused by a variety of factors, including allergies, infections, and injuries.
Common causes of red eye include:
- Conjunctivitis: Also known as pink eye, this is a common infection or inflammation of the conjunctiva (the clear tissue covering the white of the eye).
- Allergies: Allergies to pollen, dust, or other irritants can cause redness and itching in the eyes.
- Dry eyes: When the eyes do not produce enough tears or the tears evaporate too quickly, the eyes can become dry and red.
- Eye strain: Prolonged use of digital screens or reading for extended periods of time can strain the eyes and cause redness.
- Contact lens irritation: Wearing contact lenses that do not fit properly or that are not cleaned properly can cause redness and irritation.
Treatment for red eye depends on the underlying cause. Over-the-counter eye drops or antihistamines can help relieve symptoms caused by allergies or dry eyes. Prescription eye drops or antibiotics may be necessary for bacterial or viral infections.
In addition to treatment, there are several steps individuals can take to prevent red eye, including:
- Avoiding rubbing the eyes: Rubbing the eyes can cause further irritation and redness.
- Practicing good hygiene: Wash hands frequently and avoid sharing towels or makeup.
- Taking breaks from screens: Take frequent breaks when using digital screens for prolonged periods of time.
- Keeping contact lenses clean: Clean contact lenses regularly and replace them as recommended by a healthcare provider.
It is important to speak to a healthcare provider if red eye is severe, painful, or accompanied by vision changes or other symptoms.
