Are Your Eyes Sensitive to Light?

If bright lights, sunlight, or even moderate indoor lighting causes you to squint, close your eyes, or feel pain, you may be experiencing photophobia, the clinical term for light sensitivity. For Spring Valley residents who spend time outdoors in the bright Nevada sunshine, understanding the causes and treatment options for photophobia is especially relevant.

What Is Photophobia and Who Does It Affect?

Photophobia is not an eye disease itself but rather a symptom that can accompany many different conditions. People with light sensitivity often experience discomfort, headaches, or nausea when exposed to bright light. In mild cases, only intense sunlight or harsh artificial lighting triggers symptoms. In severe cases, even dim indoor light can cause significant pain.

People with lighter-colored eyes tend to be more susceptible to photophobia. Darker irises contain more pigment, which absorbs incoming light and reduces internal reflection within the eye. Individuals with very light eyes or those with albinism, a condition involving a lack of eye pigment, may experience photophobia more frequently.

What Causes Light Sensitivity?

Photophobia can result from a wide range of underlying conditions, some mild and some serious. Common causes include:

Dry eye syndrome, which reduces the protective tear film on the eye surface
Eye infections or inflammation such as conjunctivitis, uveitis, or iritis
Corneal abrasions or scratches on the surface of the eye
Migraines, which frequently include light sensitivity as a primary symptom
Certain medications, including tetracycline and doxycycline
Recovery from refractive surgery co-management procedures

In the summer months, UV-related corneal inflammation called keratitis can trigger photophobia. Wind and dry desert air can also worsen symptoms, making protective sunglasses particularly important.

In rare cases, sudden light sensitivity can signal a more serious condition such as a detached retina or a systemic illness like meningitis.

When Should You Seek Immediate Care?

If your light sensitivity is new, sudden, or worsening and the cause is unknown, seek prompt medical attention. Contact your eye doctor or visit an emergency care provider right away if you also experience any of the following:

Blurry vision or sudden vision changes
Severe eye pain or burning
Fever, chills, or stiff neck
Severe headache with nausea or vomiting
Confusion, drowsiness, or numbness
A sensation that something is stuck in your eye

These symptoms could indicate a medical emergency that requires same-day evaluation.

How Is Photophobia Treated?

The most effective approach to managing photophobia is identifying and treating the underlying cause. Depending on the diagnosis, treatment may include lubricating eye drops for dry eye, prescription anti-inflammatory drops, antibiotics for infection, or migraine-specific medications.

While working with your eye doctor to address the root cause, the following strategies can help reduce daily discomfort:

Wear sunglasses with 100 percent UVA and UVB protection whenever you are outdoors
Dim indoor lighting or use warm-toned bulbs to reduce glare
Consider photochromic lenses, which automatically darken in bright conditions and are available in prescription options
Take breaks from screens and reduce screen brightness settings
