Conjunctivitis is arguably the biggest cause of bloodshot eyes. There are three main causes of conjunctivitis: allergies, irritants, and infections. These lead to the blood vessels in the eye swelling and making it appear red and sometimes feel gritty. Most of the time, conjunctivitis will clear up on its own - but you may be prescribed eye drops if it is particularly persistent. The majority of conjunctivitis can be very contagious, so make sure not to share towels or pillows with anyone.


Burst blood vessel
A burst blood vessel in the eye is another common reason for developing bloodshot eyes - it can be caused by straining, coughing, vomiting or even heavy sneezing. Burst blood vessels can appear very alarming because they are bright red and can cover large portions of the eye. However, no treatment is usually required and the haemorrhage should fade within a couple of weeks. If your eye does not clear up after two weeks or you regularly suffer from burst blood vessels in your eye, visit your optometrist.


Scratch to the cornea
A scratch to the cornea or a particle in your eye could lead to it becoming bloodshot. Once a foreign body is removed, you may be given antibiotic eye drops and ointment to prevent an infection occurring during the healing process.
