Letโs dive in.
๐ What Is Eye Redness?
Eye redness occurs when the blood vessels in the conjunctiva (the clear tissue over the white part of your eyes) become swollen or irritated.
This can result from fatigue, dryness, infections, allergies, or even systemic health problems.
๐งพ Common Causes of Red Eyes in the Morning
1. Lack of Sleep and Eye Fatigue
- Poor sleep quality or staying up late increases pressure in the blood vessels of your eyes.
- Staring at screens all day causes eye strain, especially without breaks.
2. Dry Eyes (Dry Eye Syndrome)
- Tear production decreases during sleep.
- Poor-quality tears or reduced blinking (especially while sleeping with eyes slightly open) can lead to redness.
3. Contact Lens Irritation
- Sleeping with lenses in or wearing them too long reduces oxygen to the cornea and irritates the eyes.
4. Allergies
- Allergic conjunctivitis causes redness, itching, and watery discharge.
- Common triggers: dust mites, pollen, pet dander.
5. Infections
- Viral or bacterial conjunctivitis can be more noticeable in the morning.
- Symptoms: sticky discharge, itching, crusty lashes.
6. Serious Eye Conditions
- Conditions like uveitis, glaucoma, or scleritis can cause eye redness with pain and vision changes.
โ ๏ธ When to See a Doctor
Seek medical attention if you experience:
- Red eyes for more than 7 days

โ How to Prevent or Reduce Eye Redness
1. Use Artificial Tears

- Use 3โ4 times daily, especially after waking up
2. Follow the 20-20-20 Rule

3. Clean Hands and Avoid Rubbing Eyes

4. Use a Humidifier
