Eye pain and sensitivity to light are two of the most common optical symptoms that can lead to discomfort.

Some of the conditions that can result in these symptoms include Migraines, dry eyes, pink eyes, and injury to the cornea.

This article will discuss the causes of eye pain and light sensitivity and how to treat their symptoms.

    Corneal Abrasion is one of the most common causes of light sensitivity, resulting in eye pain.

    According to a study, it is also known as the scratched cornea.

    The cornea refers to the clear outer part covering the eye in an individual.

    A person may experience a scratched cornea due to an eye injury which can cause photophobia, leading to eye pain.

    The eye injury can happen due to blunt force or using contact lenses for longer periods.

    Eye Infection

    Conjunctivitis (Bacterial Pink Eye)

    Research states that pink eyes or Conjunctivitis can cause eye pain and sensitivity to light.

    This condition may happen due to viral, bacterial, or allergic infections causing swelling in the white part of one’s eyes.

    This swelling is often painful for the eyes and can lead to huge irritation.

    Eye infections like Keratitis can also lead to symptoms like eye pain and light sensitivity.

    Individuals experiencing Uveitis may also face ocular pain and photophobia as symptoms.

    Keratitis is a condition that results in the inflammation of one’s cornea, the clear front surface of the eyes. It is a severe condition that can result in vision loss.
    Uveitis refers to the swelling of the uvea, which is the middle part of one’s eyes. It can lead to blindness if the affected person remains untreated.


    Migraines usually lead to moderate to extreme headaches, which can disrupt the daily life of the person experiencing them.

    A study states that some people can get sensitive to light during their Migraine episodes.

    This sensitivity to light can cause pain in the eyes and even lead to nausea and vomiting.

    Dry Eye Syndrome

    Dry Eye Syndrome refers to the condition in which a person’s tear ducts do not produce enough tears or there is excessive drainage of the tears.

    It often results in dryness in the eyes, which can result in sensitivity to light or photophobia.

    The light sensitivity often affects the eyes and can cause intense eye pain in the affected individuals.

    If you wish to learn about the treatment for dry eyes, read Comprehensive Guide to Dry Eye Treatment.

    Connection between Eye Pain and Sensitivity to Light

    Eye pain and sensitivity to light are closely connected since they have the same triggers.

    When a person experiences sensitivity from looking at a bright light, they are more likely to seek a shield from it.

    This slowly lowers one’s power to look at a bright light and results in intense eye pain.

    Hence, both of these symptoms are often experienced together due to their common causes.

    These common causes include inflammation, eye injury, or underlying health conditions.
