Eye strain, or asthenia, is a common condition caused by overuse of the eye muscles. It is characterized by symptoms such as dry eyes, eye pain, headaches, and blurred vision. While eye strain itself does not cause high intraocular pressure, it can lead to headaches and even migraines, which are often associated with a feeling of pressure or pain behind the eyes. High intraocular pressure, or ocular hypertension, typically does not cause symptoms and is usually detected during eye examinations. It can, however, be a risk factor for developing glaucoma, which can lead to vision loss if left untreated.

What You'll Learn
Ocular hypertension
The condition is typically diagnosed by an eye doctor during a routine eye exam. Ophthalmologists and optometrists will take a patient's medical history, perform an examination, and may offer diagnostic tests. Intraocular pressure levels greater than 21 mm Hg confirm a diagnosis of ocular hypertension. It is important to be diagnosed early as ocular hypertension can increase the risk of developing glaucoma. Studies have shown that people with ocular hypertension have an average estimated risk of 10% of developing glaucoma over 5 years. However, this risk can be reduced by half if eye pressure is lowered through medications or laser surgery.
While ocular hypertension does not cause noticeable symptoms, people with the condition may experience eye strain. Eye strain, or eye fatigue, is a common condition caused by intense use of the eyes, such as reading, using digital devices, or driving long distances. It can also be caused by stress, fatigue, or improper lighting conditions. Symptoms of eye strain include dry, itchy, or burning eyes, blurred vision, watery eyes, light sensitivity, or difficulty keeping the eyes open. In some cases, eye strain can lead to headaches, dizziness, and even reading and learning difficulties. However, most headaches are classified as migraine- or tension-type and are not related to eye strain.

Eye strain causes
Eye strain, or asthenopia, is a common condition that occurs when the muscles around your eyes become fatigued after intensely focusing your eyes during a task. This can happen when intensely using your eyes for activities such as reading, driving long distances, playing video games, sewing, crafting, or constantly using digital devices.
Digital eye strain, in particular, has become a growing concern with the heavy use of smartphones, tablets, and other such devices. Small fonts and blue light can be hard on the eyes, and the glare from these devices can also cause eye strain. When using digital devices, people tend to blink less, leading to dry eyes, which can contribute to eye strain.
Eye strain can also be caused by insufficient lighting when performing tasks such as reading or writing, as well as stress and fatigue.
While eye strain is usually temporary and improves with rest, it can lead to symptoms such as dry, itchy, or burning eyes, blurred vision, watery eyes, light sensitivity, difficulty keeping your eyes open, headaches, and dizziness. In some cases, eye strain can be a trigger for migraines, which are often associated with a feeling of pressure or pain behind the eyes.

Eye strain symptoms
Eye strain, also known as eye fatigue, is a common condition. It is caused by intensely focusing the eyes during tasks such as reading, driving, or using digital devices like computers and cell phones. Those with prior eye conditions, such as uncorrected vision or eye muscle imbalance, are at greater risk of eye strain.
Symptoms of eye strain include:
- Dry, itchy or burning eyes
- Blurred vision
- Watery eyes
- Light sensitivity
- Difficulty keeping eyes open
- Headaches
- Dizziness
- Poor depth perception
- Nausea
- Balance issues
- Pain with eye movement
- Aching eyes or face
- Upper back and neck pain
Eye strain can often be treated with simple lifestyle changes, such as reducing glare and bright lighting, increasing room humidity, and taking regular breaks from screen time. It is important to note that blue light is not a cause of eye strain, so blue light-blocking glasses and filters are not effective in relieving eye strain.

Eye strain treatment
Eye strain, or eye fatigue, is a common condition that can be caused by intensely focusing your eyes on visually intensive tasks for prolonged periods. This can include reading, driving long distances, and constantly using digital devices such as computers, smartphones, and tablets.
- The 20-20-20 rule: One of the best ways to protect your eyes against eye strain is to take regular breaks using the "20-20-20" rule. Every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds. Even closing your eyes for a few seconds can help re-moisten your eyes and relieve some eye strain.
- Lubricating eye drops: Use lubricating eye drops to refresh your eyes when they feel dry, itchy, or burning.
- Adjust lighting and reduce glare: Eye strain can be caused by excessively bright light, either from outdoor sunlight or harsh interior lighting. When using a computer, adjust the lighting in your environment and on your screen to a level that is comfortable for your eyes. Reduce glare from surrounding lighting and reflections on your screen by using blinds, anti-glare films, or anti-reflective coatings on glasses lenses.
- Position your screen: Position your computer screen so that windows are to the side, instead of in front or behind it. Avoid working under overhead fluorescent lights, and consider using floor lamps that provide indirect "soft white" LED lighting.
- Annual eye exams: Comprehensive eye exams can help prevent and treat eye strain. During your exam, inform your eye doctor about your digital device usage and the distance between your eyes and your screen when working.
- Blue light blocking glasses: While there is no evidence that blue light from digital devices causes eye strain, using blue light-blocking glasses may be beneficial for some individuals.
If you are experiencing severe or long-term eye strain, it is recommended to consult a healthcare provider or eye care specialist to rule out any more serious conditions.

Eye strain and headaches
Eye strain, or eye fatigue, is a common condition. It can be caused by intensely focusing your eyes on a task, such as reading, using a computer, or driving long distances. Other causes include playing video games, detailed work such as writing or crafting, poor lighting, and glare from digital screens. When people use computers or other digital screens, they tend to blink less, leading to dry eyes, which can contribute to eye strain.
Eye strain can cause headaches, dry eyes, and light sensitivity. However, it is an uncommon cause of headaches. Most headaches are classified as migraine- or tension-type headaches, which have little to do with eye strain or vision issues. Nevertheless, eye strain-induced headaches can be frustrating and disruptive.
To identify whether your headache is caused by eye strain, consider what you were doing before your symptoms developed. If you were engaging in activities that require intense focus or looking at a digital screen for long periods, eye strain may be the culprit. Headaches centered around the temples or the front of the face are common symptoms of Vertical Heterophoria (VH), a form of Binocular Vision Dysfunction where the eyes have trouble staying aligned vertically.
To relieve eye strain headaches, you can try using lubricating eye drops, wearing prescription glasses, resting your eyes, using artificial tears, or taking over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs). If your headaches persist despite these measures, it is recommended to visit a doctor.

Frequently asked questions
Eye strain, or eye fatigue, is a common condition caused by overuse of the eye muscles. It can be caused by intensely focusing your eyes during a task, such as reading, writing, sewing, crafting, driving, or using digital devices.
Symptoms of eye strain include dry eyes, eye pain, headaches, and blurred vision.
Eye strain can cause headaches, which may include a feeling of pressure and pain behind the eyes. However, pressure behind the eyes may also be a symptom of a more serious condition, such as optic neuritis or Graves' disease.
If you are experiencing eye strain, try giving your eyes a rest from constant focus. If you are concerned about pressure behind your eyes, it is recommended that you consult a doctor or eye care provider to determine the underlying cause.
