- Eye Irritation: Exposure to smoke, dust, pollen, or harsh chemicals can irritate the eyes, leading to redness.
- Allergies: Allergic reactions to pet dander, pollen, or other allergens often cause red, itchy, and watery eyes.

- Eye Strain: Prolonged use of digital devices or reading can cause eye fatigue and redness.
- Contact Lens Use: Improper handling or wearing lenses longer than recommended can lead to irritation and redness.
- Injury or Trauma: Physical injury to the eye from an impact or foreign object can cause redness and swelling.
- Infections: Bacterial, viral, or fungal infections can cause the eye to appear red and swollen.
- Glaucoma: An acute attack of angle-closure glaucoma can cause redness, pain, and visual disturbances and is a medical emergency.
- Uveitis: Inflammation of the uvea (middle layer of the eye) can lead to redness, pain, and blurred vision.
