That irritating sensation of something being stuck in your eye when you blink can be both uncomfortable and concerning. This common experience, known medically as foreign body sensation, can have various causes ranging from minor irritants to underlying eye conditions that may require medical attention.
Understanding the root causes and appropriate solutions can help you address this discomfort effectively and know when to seek professional help. Let's explore the common causes, treatment options, and prevention strategies for this uncomfortable eye sensation.
Common Causes of Foreign Body Sensation
Several factors can create the feeling of something being in your eye when you blink:
Dry Eyes
One of the most common causes is dry eye syndrome, where your eyes don't produce enough tears or the tears evaporate too quickly. This can create a gritty, sandy sensation with each blink.
Corneal Abrasions
Small scratches on your cornea's surface can cause significant discomfort and a persistent feeling that something is trapped in your eye. These abrasions can occur from contact with dust, debris, or accidentally scratching your eye.
Allergies and Environmental Factors
Seasonal allergies, exposure to irritants, or environmental conditions like wind and pollution can trigger eye irritation and foreign body sensation. These factors often cause inflammation and increased sensitivity in your eyes.
Impact of Contact Lenses
Contact lens wearers frequently experience foreign body sensation due to:
- Debris trapped under the lens
- Poorly fitting contacts
- Expired or damaged lenses
- Extended wearing time
- Protein buildup on lenses
When to Seek Medical Attention
While many cases of foreign body sensation resolve on their own or with simple home care, certain symptoms warrant immediate medical attention:
- Severe pain or redness
- Changes in vision
- Light sensitivity
- Persistent discomfort despite home treatment
- Signs of infection
- Visible damage to the eye
Home Treatment and Prevention
Several strategies can help alleviate the discomfort and prevent future occurrences:
Immediate Relief Methods
Try these safe approaches for immediate comfort:
- Artificial tears or lubricating eye drops
- Gentle eye washing with clean water
- Blinking exercises

Frequently Asked Questions
What are the common causes of the feeling that something is in my eye when I blink?
Common causes include dry eyes, corneal abrasions, allergies, contact lens issues, and environmental irritants like dust or debris. Sometimes, inflammation of the eyelids (blepharitis) can also create this sensation.
How can I relieve the sensation of something rubbing in my eye caused by dry eyes or blepharitis?
Use artificial tears regularly, practice good eyelid hygiene, apply warm compresses, and consider using a humidifier. For blepharitis, gentle eyelid cleaning and prescribed medications may be necessary.
When should I see a doctor if my eye feels like it has a foreign body but nothing is visible?
Seek medical attention if you experience severe pain, vision changes, light sensitivity, or if the sensation persists for more than 24 hours despite home treatment.
Can contact lenses or environmental factors make my eyes feel like something is stuck when I blink?
Yes, both can cause this sensation. Poorly fitting or dirty contact lenses, as well as exposure to dust, wind, or allergens, can create irritation and foreign body sensation.
What home treatments or lifestyle changes help reduce eye irritation and foreign body sensation?
Regular use of artificial tears, taking screen breaks, maintaining good eye hygiene, using protective eyewear, and keeping contact lenses clean can help reduce irritation and prevent foreign body sensation.
