Many people’s eyes are bothered by bright light. A degree of photosensitivity, as a result, isn’t uncommon overall. However, the causes of photosensitivity can vary. While some are relatively benign, others may require care from an eye care provider to resolve. 

By understanding why bright light can be uncomfortable and when you should seek medical care from an eye care provider, you can make wiser choices and protect your vision. Here’s a look at common reasons why bright light may bother your eyes, as well as when to see a doctor. 

Causes of Photosensitivity 

Many people experience mild discomfort when exposed to bright light, particularly when transitioning from a darker space. For example, leaving a darkened movie theater and walking straight out into the midday sun would cause some photosensitivity in many people, so it isn’t inherently concerning. 

However, some causes of photosensitivity are potentially troubling. Several conditions have sensitivity to bright light as a symptom, which makes getting evaluated by an eye care physician wise. 

For example, eye inflammation conditions like uveitis, episcleritis, or acute iritis can cause photosensitivity. The same is true of glaucoma, meningitis, or migraines. Even a chalazion or wearing poorly fitted contacts, or keeping contacts in for an extended period, may cause photosensitivity. 

Certain medications or illicit substances can trigger photosensitivity. Corneal abrasions, corneal ulcers, and burns to the eye can lead to issues with bright light. At times, photosensitivity is a side effect of eye surgery. 

Each of the conditions and situations above can vary in severity. Additionally, some may require treatment to ensure your vision is preserved, as they can cause other types of damage beyond light sensitivity, some of which may be permanent without intervention. 

Ultimately, photosensitivity isn’t uncommon, but that doesn’t mean it should be ignored. While the occasional twinge when a bright light hits the eye after being in a dark space isn’t often cause for concern, if there are any additional symptoms – such as redness or pain – it’s best to assume that something besides normal reactions to bright light may be occurring. 

When to See an Eye Care Provider About Photosensitivity 

Generally speaking, it’s best to see an eye care provider if your photosensitivity is accompanied by certain symptoms. Redness or blurry vision that doesn’t resolve within 24 to 48 hours should be evaluated by a professional, as it could be indicative of an infection or other medical condition. 

Additionally, if your light sensitivity is severe enough that wearing sunglasses indoors or turning off indoor lights is a must, set an appointment with your eye care provider. The same goes for photosensitivity that’s painful, especially if it’s severe and repeatedly occurs or lingers.
