Tiredness: not having enough sleep can make your eyes red. That happens because it decreases the amount of oxygen that gets to your eye cells. To compensate for this change, your blood vessels dilate – hence the reddish color. The treatment is fantastic: take a nap. Blepharitis: It is the most common cause of dry eye, and it is the inflammation of the oil glands that are located in the eyelids. It’s a chronic condition, which means that there is no permanent treatment. However, it can, and it should be prevented and controlled – with good hygiene practices. Subconjunctival hemorrhage: although this condition may look really scary sometimes, there is absolutely no reason for alarm. A subconjunctival hemorrhage occurs when a small vessel from the conjunctiva starts bleeding, leaking and spreading the blood across the white part of the eye. It is painless and usually caused by sneezing, coughing, vomiting, or rubbing the eye. Unless an eye infection starts developing, your eye will heal itself back to normal. You can ease the dryness and itchiness by applying artificial tears. Dry eye: dry eye syndrome is another common disease that results as a condition of having dry eyes (when either the eye doesn’t produce enough tears or they evaporate much faster than normal). This could happen for several reasons (among which are the use of contact lenses, medication, pregnancy, and allergies). Depending on the underlying cause, treatment may range from the use of artificial tears to changing certain medications. Smoking weed: if you’re a regular smoker, you probably have already noticed that most people’s eyes turn red after smoking a joint. That’s because THC – the main psychoactive substance present in cannabis – decreases blood pressure, causing blood vessels to dilate. Having red eyes after smoking is nothing but a result of the dilation of the ocular capillaries. Don’t worry about it.
