The red colour is a result of expanded blood vessels on the surface of the eye.
Red-eye in children is usually caused by rubbing the eyes or getting something in the eye, like sand.
However, if the red-eye is persistent or associated with other symptoms, the child should be seen by a specialist.
One of the things we see more often in children nowadays is blepharitis or inflammation of the lid margin. This is now becoming known as a disease in children which affects the glands that produce oil. The eyes become sore, uncomfortable and sensitive to light.
Red-eye may also be caused by:
- Conjunctivitis, also known as “pink eye”
- Stye or a red bump on the eyelid
- Subconjunctival haemorrhage
- Dry eye syndrome
- Contact lenses
- Computer vision syndrome
- Eye injury or trauma
- Corneal ulcer
- Ocular herpes
- Whitening eye drops
- Cold and flu
- Lack of sleep
- Environment and hazards
However, redness of the eye can also signal a more serious eye condition or disease, such as uveitis or glaucoma.
If the red eye persists or worsens, you should contact Eye Clinic London for proper diagnosis and treatment.
