Bloodshot eyes may be caused by various factors. 1. Eye strain is a common cause, especially prolonged screen time on electronic devices, which can lead to dilation of blood vessels in the eyes and result in redness. 2. Eye injuries, such as blunt trauma or scratches, may cause blood vessels to rupture, leading to visible redness. 3. Eye infections, including inflammatory conditions like conjunctivitis, can also cause blood vessel dilation and increased redness. 4. Elevated intraocular pressure, associated with conditions such as hypertension or cardiovascular and cerebrovascular diseases, may make ocular blood vessels prone to rupture and bleeding, resulting in bloodshot eyes. Increased eye redness may also be accompanied by symptoms such as dryness, pain, and dizziness, indicating that eye health has been compromised. Patients should seek proper diagnosis and treatment based on their specific condition.
