Surface pain is usually caused by irritation, infection, or trauma. Often, it is easily treated with eye drops or rest. Eye pain deeper in the eye may require more in-depth treatment. Any pain accompanied by vision loss is an emergency.

Eye pain is common, but it’s rarely a symptom of a serious condition. Most often, the pain resolves without medicine or treatment. Eye pain is also known as ophthalmalgia.

Depending on where you experience the discomfort, eye pain can fall into one of two categories: Ocular pain occurs on the eye’s surface, and orbital pain occurs within the eye.

Eye pain that occurs on the surface may be a scratching, burning, or itching sensation. Eye pain that occurs deeper within the eye may feel aching, gritty, stabbing, or throbbing.

Eye pain accompanied by vision loss may be a symptom of an emergency medical issue. Call your ophthalmologist immediately if you begin to lose your vision while experiencing eye pain.

The following may cause eye pain that originates on the surface of the eye:

Foreign object

The most common cause of eye pain is simply having something in your eye. Whether it’s an eyelash, a piece of dirt, or makeup, having a foreign object in the eye can cause irritation, redness, watery eyes, and pain.


The conjunctiva is the tissue that lines the front of the eye and the underside of the eyelid. It can become infected and inflamed. Often, this is caused by an allergy or infection.

Though the pain is usually mild, the inflammation causes itchiness, redness, and discharge in the eye. Conjunctivitis is also called pink eye.

Contact lens irritation

People who wear contact lenses overnight or don’t disinfect their lenses properly are more susceptible to eye pain caused by irritation or infection.

Corneal abrasion

The cornea, the clear surface that covers the eye, is susceptible to injuries. When you have a corneal abrasion, you will feel as if you have something in your eye.

However, treatments that typically remove irritants from an eye, such as flushing with water, won’t ease the pain and discomfort if you have a corneal abrasion.


Chemical burns and flash burns to the eye can cause significant pain. These burns are often the result of exposure to irritants such as bleach or to intense light sources, such as the sun, tanning booths, or the materials used in arc welding.


Blepharitis occurs when oil glands on the eyelid’s edge become infected or inflamed. This can cause pain.


A blepharitis infection can create a nodule or raised bump on the eyelid. This is called a sty or a chalazion. A sty can be very painful, and the area around the sty is usually very tender and sensitive to touch. A chalazion isn’t usually painful.

Eye pain felt within the eye itself may be caused by the following conditions:


This condition occurs as intraocular pressure, or pressure inside the eye, rises. Additional symptoms caused by glaucoma include nausea, headache, and loss of vision.

A sudden rise in pressure, called acute angle closure glaucoma, is an emergency, and immediate treatment is needed to prevent permanent vision loss.

Optic neuritis

You may experience eye pain accompanied by a loss of vision if the nerve that connects the back of the eyeball to the brain, known as the optic nerve, becomes inflamed. An autoimmune disease or a bacterial or viral infection may cause the inflammation.


An infection of the sinuses can cause pressure behind the eyes to build. As it does, it can create pain in one or both eyes.


Eye pain is a common side effect of migraine attacks.


Penetrating injuries to the eye, which can occur when a person is hit with an object or is involved in an accident, can cause significant eye pain.


While uncommon, inflammation in the iris can cause pain deep inside the eye.

If you begin experiencing vision loss in addition to eye pain, this may be a sign of an emergency situation. Other symptoms that need immediate medical attention include:

  • severe eye pain
  • eye pain caused by trauma or exposure to a chemical or light
  • abdominal pain and vomiting that accompanies eye pain
  • pain so severe it’s impossible to touch the eye
  • sudden and dramatic vision changes

The treatment for eye pain depends on the cause of the pain. The most common treatments include:

Home care

The best way to treat many of the conditions that cause eye pain is to allow your eyes to rest. Staring at a computer screen or television can cause eyestrain, so your doctor may require you to rest with your eyes covered for a day or more.


If you frequently wear contact lenses, give your corneas time to heal by wearing your glasses.

Warm compress

Doctors may instruct people with blepharitis or a sty to apply warm, moist towels to their eyes. This will help to clear the clogged oil gland or hair follicle.


If a foreign body or chemical gets into your eye, flush your eye with water or a saline solution to wash the irritant out.


Antibacterial drops and oral antibiotics may be used to treat infections of the eye that are causing pain, including conjunctivitis and corneal abrasions.


Eye drops and oral medicines can help ease the pain associated with allergies in the eyes.

Eye drops

People with glaucoma may use medicated eye drops to reduce the pressure building in their eyes.


For more serious infections, such as optic neuritis and anterior uveitis (iritis), your doctor may give you corticosteroids.

Pain medications

If the pain is severe and causes an interruption to your day-to-day life, your doctor may prescribe a pain medicine to help ease the pain until the underlying condition is treated.


Surgery is sometimes needed to repair damage done by a foreign body or burn. However, this is rare. Individuals with glaucoma may need to have a laser treatment to improve drainage in the eye.

Most eye pain will fade with no or mild treatment. Eye pain and the underlying conditions that cause it rarely lead to permanent damage to the eye.

However, that’s not always the case. Some conditions that cause eye pain may also cause problems that are more serious if they aren’t treated.

For example, the pain and symptoms caused by glaucoma are a sign of an impending problem. If not diagnosed and treated, glaucoma can cause vision problems and eventually total blindness.

Your vision is nothing to gamble on. If you begin to experience eye pain that isn’t caused by something like an eyelash in the eye, make an appointment to see your eye doctor as soon as possible.

Eye pain prevention starts with eye protection. The following are ways you can prevent eye pain:

Wear protective eyewear

Prevent many causes of eye pain, such as scratches and burns, by wearing goggles or safety glasses when playing sports, exercising, mowing the lawn, or working with hand tools.

Construction workers, welders, and people who work around flying objects, chemicals, or welding gear should always wear protective eye gear.

Handle chemicals with caution

Direct chemicals and potent agents such as household cleaners, detergents, and pest control. Spray away from your body when using them.

Exercise caution with children’s toys

Avoid giving your child a toy that can injure their eyes. Toys with spring-loaded components, toys that shoot, and toy swords, guns, and bouncing balls can all injure a child’s eye.

Contact lens hygiene

Clean your contacts thoroughly and routinely. Wear your glasses on occasion to allow your eyes time to rest. Don’t wear contacts longer than they are intended to be worn or used.
