Causes

• Cataracts, myopia and retinitis pigmentosa may impact your ability to see well at night. Glaucoma medications that constrict the pupil could also contribute to the condition.
  
  

Treatment

• Depending on the cause, treatment ranges from getting a new pair of eyeglasses, changing glaucoma medications or surgery on the eye.
  
  

Considerations

• Night blindness could result in difficulty driving at night. Those afflicted may find it challenging to identify or distinguish among different sources of light.
  
  

Warning

• According to Gui-shuang Ying, an assistant professor of ophthalmology at the University of Pennsylvania School of Medicine, poor night vision could be a precursor of macular degeneration.
  
  

Prevention

• Getting adequate Vitamin A may help protect the eyes against night blindness. Eggs, meat and dairy products as well as dark leafy greens are good sources.
