Causes of Sharp Pain in Your Eye

Sharp eye pain can be sudden or gradual, ranging from mild discomfort to severe, stabbing, burning, or throbbing sensations. While minor causes, such as dry eye or debris, are often manageable, serious conditions like infections or glaucoma require prompt treatment to protect vision and long-term eye health.

1. Foreign Objects

Foreign objects, such as dust, fingernails, pollen, or eyelashes, can scratch or become lodged in your eye during normal activities. Liquid irritants, including chemicals, can also cause sharp pain in your eye. Symptoms can include pain with every blink and excessive watering.

Depending on the type, size, and positioning of the foreign object, treatment can include:

• Gently flushing out the debris with water or eye drops
• Placing a cotton-tipped swab on the object to remove it
• Medical attention to remove metal or glass fragments

2. Eye Infections

Eye infections caused by bacteria, viruses, fungi, or parasites can result in sharp pain in your eye. Common eye infections include;

• Conjunctivitis: Also known as pink eye, conjunctivitis is inflammation of the conjunctiva, the clear membrane that covers your inner eyelid and the white part of your eyeball. Viruses, bacteria, or allergens typically cause this condition.
• Keratitis: Keratitis is an inflammation of the cornea, the clear, round dome that covers your iris and pupil. A minor injury or a foreign object in your eye can cause this. Bacteria, viruses, fungi, or parasites can cause an infectious version of this condition.
• Orbital cellulitis: This is a severe infection of the fat, muscles, and tissue surrounding your eye, often caused by a sinus infection, facial infection, or eye trauma.
• Endophthalmitis: This eye infection affects the fluids and tissues inside your eyeball. It typically occurs after eye surgery, an injection into the eyeball, or an eye injury.
• Blepharitis: This common eyelid infection or inflammation is caused by rosacea, a common skin condition with prominent blood vessels of the face and eyelids, or overgrowth with common organisms like Staphylococcus aureus bacteria or Demodex (a mite that lives on the eyelids).
• Other viruses and sexually transmitted infections (STIs): You may transfer infections such as herpes, syphilis, gonorrhea, pubic lice, and HIV/AIDS to your eyes, resulting in an eye infection.

Eye infections typically require medical attention. Without proper treatment, they can cause severe damage. Common treatments for eye infections depend on the type of infection and include:

3. Eye Irritations and Diseases

Conditions that irritate the sensitive inner eyelid or eyeball can cause sharp pain in your eye. These issues can include:

• Corneal abrasions: Contact lenses or foreign objects can scratch or scrape the epithelium, the outer layer of your cornea. This can expose the nerve endings in your cornea, making it very sensitive.
• Dry eye: Dry eye occurs when your eyes don’t produce enough tears to keep your eyes moist. This can occur due to certain diseases, dry eyes, contact lens use, or the use of certain medications.
• Anterior uveitis: Caused by inflammation of the iris, the colored part of your eye, uveitis is usually related to an injury, an autoimmune condition, or an infection.
• Glaucoma: This condition occurs when fluid accumulates in the front of your eye. It creates pressure that can damage the optic nerve.

Treatment for eye irritations depends on the cause. This can include:

• An eye patch over the affected eye to promote healing of a corneal abrasion
• Artificial tears to increase moisture, reduced by dry eye or corneal abrasion
• Steroid or dilating eyedrops, especially for anterior uveitis
• Prescription eye drops to lower the harmful eye pressure that occurs in glaucoma
• Laser treatment or surgery to drain fluid and reduce eye pressure in glaucoma

4. Headaches

Certain types of headaches can cause sharp, stabbing pain around your eye. These include:

• Cluster headaches: This type of headache causes pain on one side of your face, from your neck to your temple. Light sensitivity can also occur.
• Migraine headaches: A migraine headache typically causes severe throbbing pain in the head, temples, and/or behind one eye or ear. Sensitivity to sound or light, nausea, and vomiting are common.

Depending on the type and severity of headaches causing eye pain, you may benefit from one of the following treatments:

When to Seek Immediate Medical Attention

Getting appropriate medical attention for a serious eye problem can prevent long-term damage. Seek immediate care from an eye doctor, your healthcare provider, or an urgent care/emergency department if you have any of the following symptoms with sharp pain in your eye:

• Evidence of a cut or scratch on your eye
• A foreign object stuck in your eye
• Seeing halos around lights
• Appearance of an opaque cornea
• Fever, chills, or other signs of a bodily infection
• Chemical products in your eyes
• Eye redness, swelling, discharge, or pressure
• Bulging eyeballs
• An inability to move your eyes through their normal range
• Nausea, vomiting, or headache
• A change in eyesight, such as blurred vision or diplopia (double vision)
• Uncontrollable bleeding

Key Takeaways

• Small debris and other irritants, which can be rinsed out with clean water or artificial tears, are the most common causes of sharp pain in your eye.
• Sharp pain in your eye that persists, worsens, or accompanies other symptoms should be evaluated by an eye doctor or other healthcare provider to determine the cause and proper treatment.
• Early diagnosis and treatment are crucial for many causes of sharp eye pain, as some conditions can lead to vision loss without prompt intervention.
