Light Sensitivity & What It Means
You step outside on a bright afternoon and your eyes immediately start watering. You squint, feel a sharp ache behind your eyes, and reach for your sunglasses like they’re a lifeline. Most people brush this off as normal sensitivity to the sun, but when light that doesn’t bother others leaves you in discomfort, something more may be going on.
Light sensitivity, also called photophobia, happens when your eyes react with pain or discomfort to light levels that most people would find tolerable. Photophobia can affect one or both eyes, and it can come on suddenly or build gradually over time.
At Total Vision Encinitas, we offer comprehensive eye exams to help you find relief from persistent symptoms. A thorough eye exam can get to the bottom of your discomfort.
Signs You Might Have Light Sensitivity
Light sensitivity doesn’t always feel the same from person to person. Some common signs to watch for include:
- Squinting, eye pain, or watering when exposed to bright light.
- Headaches that seem to start or get worse with light exposure.
- A strong urge to close your eyes or cover them in lit environments.
Common Causes of Light Sensitivity
Light sensitivity is a symptom, not a condition on its own. In order to help you find relief, we’ll need to find the underlying problem.
Eye-Related Causes
Dry eye is one of the more frequent culprits. When your eyes get dry, even mild light can feel harsh. Scratches on the cornea, bacterial or viral eye infections, and inflammation like uveitis or keratitis can also make your eyes more sensitive to light. Spending time outdoors without UV protection can leave your eyes irritated and overly sensitive for hours afterward.
Whole-Body Causes
Migraines are strongly linked to light sensitivity, and that includes ocular migraines, which can happen without the classic head pain. Certain prescription medications also cause light sensitivity as a side effect, while some systemic health conditions can have similar effects.
When Light Sensitivity Needs Prompt Attention
Most light sensitivity has a manageable cause, but there are situations where waiting isn’t a good idea. If you notice any of the following symptoms, get your eyes checked out right away:
- Sudden onset of light sensitivity paired with severe eye pain or changes in your vision.
- Sensitivity accompanied by fever, a bad headache, or neck stiffness.
- Recent eye injury or any exposure to a chemical.
- Thick discharge or intense redness in the eye.
- Nausea or vomiting at the same time as your symptoms.
- Sudden vision loss in one or both eyes.
If you experience any of the above, Total Vision Encinitas offers emergency eye care. Come visit us immediately.
What an Eye Doctor in Encinitas Can Do for Light Sensitivity
Diagnosis
Figuring out the cause starts with a thorough eye exam. We can evaluate your eyes using a slit-lamp to get a close look at the cornea, lens, and other structures. We’ll also check your eye pressure as part of this process. In some cases, imaging or additional testing can help clarify what’s going on.
Treatment Depends on the Cause
There’s no single fix for light sensitivity. Depending on what an eye exam reveals, options may include prescription eye drops, dry eye therapy, or a review of medications that may be contributing to your symptoms. We may also recommend protective eyewear. Follow-up visits help track how your eyes are responding over time.
Simple Ways to Manage Light Sensitivity at Home
While the right care plan comes from your eye doctor, a few everyday habits can often offer some amount of relief.
- Wear UV-protective sunglasses every time you head outdoors, even on cloudy days.
- Use preservative-free artificial tears to keep dry eyes more comfortable.
- Follow the 20-20-20 rule: every 20 minutes of screen time, look at something 20 feet away for 20 seconds.
Everyday Adjustments That Help
Inside your home, small changes can add up. Dim any overhead lights, and swap out harsh fluorescent bulbs for softer options. Make sure to stay hydrated and get enough sleep at night. If you spend a lot of time in front of screens, the 20-20-20 rule is a simple reset that takes seconds but helps to manage eye strain.
If you’re experiencing light sensitivity, Total Vision Encinitas is here to help you get to the bottom of the problem. Schedule a comprehensive eye exam and take the first step toward feeling more comfortable in any light.
