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.

What Exactly Is a Black Eye?

A black eye, also known as a periorbital hematoma, is usually not an injury of the actual eye (which is why it is called “periorbital”- around the eye). It typically occurs when there is an injury to the face or the eye socket which causes bleeding beneath the skin and bruising. The term, “black eye” comes from the dark coloring of the bruising that occurs underneath the skin around the eye.

When a blunt force hits the eye socket, this can cause capillaries in the area to burst, causing hemorrhaging, also known as a hematoma. This blood can accumulate in the eye socket and as it begins to be reabsorbed into the surrounding tissues, the colors of the bruising begin to change. That’s why you will often notice the coloring of the black eye to go from a dark purplish-red color to brownish and then yellow.

Sometimes along with the external bruising, you might also notice a small amount of bleeding on the white surface of the eye, which is called a subconjunctival hemorrhage. This is when the tiny blood vessels on the white sclera are broken and leak blood. It’s generally harmless but sometimes looks scarier to the patient than the black eye does. This condition will also reabsorb on its own and is nothing to be concerned about.

While most black eyes can look pretty serious due to the dramatic color, an uncomplicated black eye will typically heal within a week to ten days. If it doesn’t, there could be a more serious issue such as a bone fracture or an orbital blowout fracture.This could present with restricted eye movement, especially if looking up or down, and numbness of the cheek and/or upper lip on the same side as the black eye. The eye may even appear sunken in. Further, if there is bleeding within the actual eye (called a hyphema) or floaters or flashes in the vision, then it is definitely advisable to see your eye doctor as soon as possible. These could be signs of more serious damage such a corneal or retinal damage and can lead to vision loss.

Treatment for a Black Eye

Usually, the best treatment for a black eye is to apply a cold compress (or even better, a bag of frozen vegetables, which is more flexible and can conform to the contours of the face) directly on the area. The cold will reduce swelling and constrict capillaries to reduce internal bleeding as well. Apply the cold for about 15-20 minutes every hour. If there is pain, over the counter pain medications can help.

If however, you experience any of the following symptoms, you should seek medical attention:

  • Blood on the surface of the eye or a visible incision on the eye
  • Vision changes such as double vision, blurred vision, loss of vision or the appearance of floaters
  • Loss of consciousness, dizziness or fainting
  • Loss of eye movement
  • Persistent headaches
  • Blood or fluids coming from the ears or nose
  • Vomiting
  • Signs of infection such as excessive swelling, pus, redness or a fever
  • Severe pain

In addition to blunt trauma, black eyes can be caused by sinus infections, nasal or eye surgery or other infections in the area such as the teeth infections or cellulitis (a serious infection that can occur around the eyes). A skull fracture can also cause both eyes to turn black, sometimes known as raccoon eyes.

Unless you notice any severe symptoms you can rest assured that your black eye is a bruise just like anywhere else on the body and with a little care, rest and patience, it will clear up in no time.
