Fact checkedWhat is Reduced night vision?
Reduced night vision, also known as nyctalopia, refers to difficulty seeing in low-light conditions, such as at night or in dimly lit environments. This can make driving at night, navigating dark spaces, or even enjoying evening activities more challenging. Understanding why night vision diminishes can help you address it and take control of your eye health.
Symptoms of Reduced night vision
If you experience reduced night vision, you may notice:
- Difficulty seeing in dimly lit or dark environments
- Increased glare or halos around lights at night
- Struggling to adjust to changes in light conditions, like moving from indoors to outdoors
- The need for brighter lights than usual to see clearly at night
What causes Reduced night vision?
Reduced night vision can be caused by:
- Aging: As we get older, the eye's ability to adjust to light decreases, leading to poorer night vision.
- Vitamin A deficiency: Vitamin A is essential for maintaining healthy vision, and a deficiency can impair your ability to see in low light.
- Cataracts: Clouding of the lens can reduce the clarity of vision, especially in low light.
- Retinal diseases: Conditions like retinitis pigmentosa or macular degeneration can affect the retina and impair night vision.
- Diabetes: High blood sugar can damage the blood vessels in the retina, affecting vision, especially at night.
Risk factors for Reduced night vision
You may be more likely to experience reduced night vision if:
- You are over 50 years old
- You have a history of cataracts, retinal diseases, or diabetes
- You have a vitamin A deficiency
- You are nearsighted

How is Reduced night vision treated?
Treatment for reduced night vision depends on the underlying cause:
