4 Facts About Night Blindness, from Park Ophthalmology

The beginning of Daylight Saving Time was a welcome change to Triangle residents who enjoy more daylight hours in the evenings. It’s also helpful for those who find driving and other tasks more difficult at night. Beth R. Friedland MD knows that many factors can cause night blindness, which makes it hard for some patients to see their surroundings in dim light. Ophthalmologists call the condition Nyctalopia and it doesn’t mean complete blindness at night, but sometimes it can seem that way. In its continuing patient education series, Park Ophthalmology has compiled some key points about night blindness.

Park Ophthalmology assesses four important facts about the basics of night blindness:

  • Human vision: The human eye is essentially color blind in the dark, seeing only black, white and gray. All humans see less well in the dark than in bright light. In dim areas, movement is easier to see than stationary objects. It takes time for eyes to adjust from bright to low light, but those with night blindness take longer than normal to adjust.
  • Symptoms: One of the first signs people have of night blindness is trouble driving. They may also have trouble recognizing faces in a darkened setting, or navigating through a darkened room. Eyes can take up to 30 minutes to completely adjust to a darkened setting, but someone with night blindness may find even that interval isn’t enough for good vision.
  • Causes: Many different conditions contribute to night blindness. Some of those conditions include nearsightedness, medicine used to treat glaucoma, cataracts, diabetes, too little Vitamin A and keratoconus (steeply curved corneas).
  • Treatments: Depending on the cause, some night blindness can be treated. Cataract surgery can be helpful. A new prescription for contacts or eyeglasses may also make a difference. Only an Ophthalmologist can determine the cause and provide treatment.
