3. Rubbing the Eyes
The cause of burst blood vessels in the eyes (or the appearance of permanent or semi-permanent bloodshot eyes) isn’t always as serious as having high blood pressure or an increased risk of having a heart attack or stroke – sometimes, the cause is much less serious and is instead related to something the patient habitually does (often without noticing).
Frequently touching or rubbing the eyes can be seen as a habit for many people without them realizing they do it; the same way, many people do this when they are tired, sick or lost in thought – and all of these can mean that you irritate the eyes enough through this action to cause blood vessels to burst.
Avoid rubbing or touching the eyes: It only puts the eyes at risk, and it further increases your risk of transferring infections from your hands and what they might have touched through to the eyes.
