Are Your Eyes Sensitive to Light?

Light sensitivity, also known as photophobia, is a condition in which bright light - either natural sunlight or artificial light -  can cause significant discomfort, pain and intolerance. People that experience light sensitivity will find themselves needing to close their eyes or squint when exposed to light and often experience headaches and nausea as well.  In mild cases, the discomfort accompanies exposure to bright lights or harsh sunlight, but in severe cases even a small amount of light can cause pain and discomfort.  

Photophobia is more common in individuals with light eyes. This is because the greater amounts of pigment in darker eyes help to protect the eye from the harsh rays of light. The darker pigment of the iris and choroid absorbs the light, rather than reflecting the light and causing internal reflection or glare experienced by those with lighter eyes. People with albinism, which is a total lack of eye pigment, also experience significant light sensitivity for this reason. 

Acute photophobia is usually a symptom that accompanies a condition such as an eye infection or irritation (such as conjunctivitis or dry eyes), a virus, or a migraine (light sensitivity is one of the most common symptoms of migraines). It could also be caused by something more serious such as an eye condition like a corneal abrasion, a detached retina, uveitis or iritis or a systemic disease like meningitis or encephalitis. Light sensitivity is also a side effect of refractive surgery (such as LASIK) and some medications (such as tetracycline and doxycycline).  

How to Deal with Photophobia

The most effective way to reduce the discomfort caused by photophobia is to stay out of sunlight and dim indoor lights as much as possible while you are experiencing symptoms. Wearing dark sunglasses and keeping your eyes closed may also provide some relief. 

In the summer it is more common for UV to trigger corneal inflammation (keratitis) and cause photosensitivity as well. Wind and eye dryness can also set off photosensitivity, which are more good reasons to wear sunglasses. 

If the sensitivity is new and the cause is unknown, you should seek medical attention immediately, especially if you experience any of the following symptoms:  

  • Blurry vision
  • Burning or pain in the eye
  • Fever and chills
  • Confusion and irritability
  • Severe headache
  • Drowsiness
  • Stiff neck
  • Nausea and vomiting
  • Numbness
  • Foreign body sensation

In cases where the photophobia is a symptom of an underlying issue, treating the issue will likely cause relief in your sensitivity. This will vary depending on the ailment but could include pain medications, eye drops or antibiotics, or anti-inflammatory medications. If the sensitivity is mild due to your genetic predisposition or a result of surgery, make sure you take your sunglasses every time you leave the house. People who wear prescription eyeglasses may consider photochromic lenses which automatically darken when exposed to light. 

If you are uncomfortable, speak to your eye doctor about the best options for your condition.

To our valued patients,

During these challenging times, we feel it’s especially important to keep you informed of what we are doing to keep you safe. The health and safety of our patients is our primary goal. The impact of the COVID-19 pandemic remains fluid and as such we have made the following changes in our clinic as we strive to maintain the highest standards of care for you our patients:

* Modified schedule. Anyone entering the clinic will need an appointment. There will only be one patient allowed in the clinic at one time to ensure social distancing. Other family members are not permitted in. You can continue to call the clinic to make these appointments. Seniors 60 and over will kindly be asked to reschedule for a safer time in the future.

* All patients must sign a form declaring that they do not have a fever, sore throat, cough, runny nose and other flu-like symptoms including aches and pains. They also must declare that they are practicing social distancing in accordance with the Governor of Washington’s mandate.

* All common surfaces will be disinfected in accordance with current guidelines and protocols after each and every patient and before a new patient enters the clinic. This includes instruments and eyeglass frames that have been handled.

Thank you for your patience and understanding during this difficult time. Our thoughts and prayers are with you. Together, we will get through this.

Warmest regards,

Dr. Osborne and staff
