  3. Eyestrain: While eyestrain is a common cause of pain behind the eyes, there is limited research on the topic. However, studies have shown that taking breaks from digital devices, adjusting lighting and screen settings, and practicing eye exercises can help prevent and alleviate eyestrain.
  4. Cluster headaches: Cluster headaches are a rare type of headache that affect less than 1% of the population. They are characterized by severe pain behind the eyes and can be accompanied by other symptoms like nasal congestion and tearing. Medications like sumatriptan and oxygen therapy have been shown to be effective in treating cluster headaches.
  5. Optic neuritis: Optic neuritis is a rare condition that affects around 1 in 5,000 people. It can cause pain behind the eyes, loss of vision, and other vision problems. It is often associated with multiple sclerosis (MS) and may be an early symptom of the condition. Treatment may include medications to reduce inflammation and manage MS symptoms.
  6. Trauma: Trauma to the head or eyes can cause pain behind the eyes. Depending on the severity of the injury, treatment may include medications, surgery, or other interventions.

  • ophthalmologists, specializing in eye issues

This pressure will often be due to simple headaches or sinus conditions, which are easy to deal with and unlikely to cause complications.

Your medication may include:

  • ibuprofen, aspirin, or acetaminophen to treat headaches

Eye Pressure and Glaucoma

Research shows that high eye pressure increases your risk for glaucoma. Experts believe that when the pressure inside your eye gets too high, it can damage the optic nerve and cause vision loss. And studies show that lowering eye pressure can help stop vision loss from glaucoma. That’s why it’s important to control the pressure inside your eyes.

But not everyone with high eye pressure will develop glaucoma — and some people with normal eye pressure get glaucoma. Whether you develop glaucoma depends on the amount of pressure your optic nerve can handle — and this amount is different for each person. For most people, eye pressure above 21 is higher than normal.

Getting regular dilated eye exams can help your eye doctor figure out what level of eye pressure is normal for you.

The pressure in your eye gets higher when fluid can’t drain normally out of the front of your eye.  
Between the cornea (clear front layer of the eye) and the iris (colored part of the eye), there’s a space called the anterior chamber. Fluid normally flows through this space and out of an opening where the iris and cornea meet. The opening has spongy tissue in it, called the trabecular meshwork. The fluid passes through the meshwork to drain out of the eye.  
Sometimes the trabecular meshwork blocks the fluid from draining back into the bloodstream, which increases pressure inside the eye. This pressure buildup is shown in the diagram below. 

Pressure behind eyes and Headache

In some cases pain behind left eye can be due to a pressure headache and this is when you experience increased pressure in a specific area. The pressure in this area will surround the tissue as well as press on the nerve fibers and this combination leads to the activation of pain receptors. The cause of pressure headaches can vary widely including sinus congestion or eye problems such as glaucoma.

Sinus headaches are caused by sinus infections and have similar symptoms to cluster headaches. The pain occurs in a specific area and is pressure-like and is made worse by any sudden head movements (such as bending forward). It also gets worse during the morning due to draining and collecting of mucus. Sinus headaches are also frequently accompanies by moderate to mild fever, postnasal drip, sore throat and green or yellow nasal discharge.

An eye migraine is also known as a retinal, basilar, opthalmoplegic, ophthalmic or ocular migraine. These migraines more commonly affect kids and young men and tend to cause pain in only one of your eyes. In many cases eye migraines are accompanied by nausea or congestion. They can also include symptoms related to the vision such as dilated pupils, drooping eyelids or double vision. You should always consult your doctor if you experience these problems to rule out underlying conditions.
