What does red eye look like?

When you see your eyes red in the white area, it can be due to swelling of blood vessels in the eyes. 

There are cases of subconjunctival hemorrhage, when these tiny blood vessels break, leading to red eye. 

If the redness in your eyes is due to an injury, the blood vessels dilate and allow more blood to get inside for fast healing. This opening is what causes red eye. 

Your eyes can feel the following things:

  • You won’t see anything until you see the redness
  • You may feel itchiness like something is stuck in your eyes
  • Tender
  • Very dry or watery
  • Goopy or crusty
Warning
In some cases, a red eye can be severe if it’s a symptom of another disease.

Common causes of eye redness

In this section, we will discuss all the possible causes of red eyes and the pain behind them. 

Dry eyes

They lubricate and protect the eyes. When this doesn’t happen, it leads to dry eyes

The issue is more prevalent among women, adults over 50, and those who utilize contact lenses.

You may notice that your eyes become red when it’s dry. Some of the symptoms include:

  • A scratchy, stinging, or burning sensation
  • Eye irritation
  • Light sensitivity 
  • Blurred vision

Conjunctivitis
