A scratchy sensation feels like sandpaper or a foreign body on the eye. It typically arises from surface irregularities or dryness.
Likely Explanations
Dry eye, blepharitis, and exposure to wind or air conditioning are common causes. Corneal abrasions, foreign bodies under the lid, and poorly fitting contact lenses also create scratchiness, often with watering and light sensitivity.
- Symptoms may worsen with blinking as the lid rubs over the surface
- Allergic conjunctivitis can cause itchy, scratchy discomfort
- Recurrent corneal erosion leads to sudden scratchiness on waking
- Debris trapped behind contact lenses intensifies the feeling
Next Steps
Lubricating drops and lid hygiene help many mild cases, but persistent scratchiness, especially with reduced vision or marked redness, needs examination to rule out abrasion or embedded foreign material.
- Contact lenses should be removed until the cause is clarified
- Eye rubbing can worsen surface damage and should be avoided
- Protective eyewear outdoors reduces environmental irritation
- Prompt treatment of abrasions prevents infection and scarring
