Light sensitivity, or photophobia, affects many people and can arise from a variety of causes. Sometimes, it’s a symptom of an underlying condition, while other times, it may be the main issue itself. Here, we look into the condition of photophobia, its common triggers, and effective ways to manage your sensitivity to light.

What is Light Sensitivity (Photophobia)?

Photophobia describes an unusual or extreme sensitivity to light that can occur as a standalone issue or as a symptom of another problem. If you notice new or increasing light sensitivity, it’s important to consult an optometrist to determine the root cause.

Typically, our pupils constrict in response to light to regulate how much light enters the eye, controlled by the iris sphincter muscle. When there’s a disruption in this process—whether due to eye conditions, brain response, or medications—you may experience photophobia.

Common Causes of Light Sensitivity

Understanding the source of your light sensitivity is essential for treatment, and an eye care professional can help narrow down the possible causes.

Eye Conditions

Certain eye issues can interfere with light processing, increasing sensitivity. Common conditions include:

  • Dry eyes
  • Corneal abrasions (scratches on the eye’s surface)
  • Cataracts (clouding of the eye’s lens)
  • Glaucoma and other retinal issues

Migraines and Headaches

Photophobia often accompanies migraines and headaches due to brain overstimulation. Sitting or lying down in a dark room can provide relief during these episodes.

Infections and Inflammation

Infections like conjunctivitis (pink eye) and inflammation, such as uveitis, can also cause photophobia. These conditions can be addressed with medication and eye care.

Medications and Additional Factors

Some medications, including certain antibiotics, antidepressants, and antihistamines, may increase light sensitivity. Eye surgery (such as LASIK), eye or head injuries (like concussions), and trauma can also contribute to photophobia. If a necessary medication is causing symptoms, discussing alternatives or management strategies with your physician and optometrist may help.

Tips to Manage Light Sensitivity

If you experience light sensitivity, here are some practical tips for relief:

  • Wear polarized sunglasses outdoors or use blue light filters for screens.
  • Adjust screen brightness and indoor lighting to create a comfortable environment.
  • Take regular breaks from bright or artificial lights to give your eyes a rest.
  • Stay hydrated and schedule regular eye exams to keep your eye health in check.
