If you struggle to see clearly while driving at night, you may be experiencing night blindness. Also known as nyctalopia, night blindness is not an eye disease but a symptom of an underlying vision problem. It can make it difficult to see in low-light conditions, which can impact your ability to drive, navigate dimly lit spaces, or adjust to changes in lighting.
At Opticare Vision Center in Ohio and Kentucky, our experienced eye doctors can diagnose, manage, and treat night blindness using digital eye exams. With our help, you can regain your confidence and enjoy nighttime activities again.
What Causes Night Blindness?
Night blindness can result from various eye conditions or health issues, including:
- Vitamin A Deficiency: Vitamin A is essential for maintaining a clear cornea and producing rhodopsin, a protein that helps you see in low light. While uncommon in North America, a deficiency in this vitamin can lead to night blindness.
- Cataracts: Cataracts occur when proteins build up and cloud the eye’s lens, impairing vision, especially at night or in poor lighting.
- Diabetic Retinopathy: Damage to the blood vessels and nerves in the eyes due to diabetes can cause vision loss, including difficulty seeing at night.
- Glaucoma: This group of eye diseases is associated with increased pressure in the eye, damaging the optic nerve. Both glaucoma and the medications used to treat it can contribute to night blindness.
- Myopia (Nearsightedness): Individuals with this refractive error may experience blurry distant vision and halos around lights at night, leading to difficulty seeing in the dark.
- Keratoconus: An irregularly shaped cornea causes blurred vision and increased sensitivity to light and glare, which can be particularly problematic at night.
- Retinitis Pigmentosa (RP): A progressive genetic eye disease that often leads to night blindness and peripheral vision loss.
- Usher Syndrome: A genetic condition that causes hearing and vision loss, including night blindness and retinitis pigmentosa.
Symptoms of Night Blindness
Night blindness is a symptom of underlying vision problems, and it’s important to get your eyes checked regularly to ensure your vision is in good health. Contact your eye doctor if you notice any of the following symptoms:
- Reduced contrast sensitivity
- Difficulty seeing people or objects outdoors at night
- Trouble seeing in dimly lit places, such as movie theatres
- Difficulty adjusting to darkness while driving
- Excessive squinting at night
- Trouble adapting from bright to dark environments
Treatments for Night Blindness
To effectively treat night blindness, your eye doctor will first diagnose the underlying cause. Depending on the cause, treatment for night blindness includes:
- Vitamin A Supplements: In cases of vitamin A deficiency, taking supplements or consuming vitamin-A-rich foods can help restore night vision.
- Eyeglasses or Contact Lenses: Myopia can often be corrected with prescription eyeglasses or contact lenses.
- Medications or Surgery: Conditions like glaucoma or cataracts may require medical treatment or surgery to restore vision.
- Low Vision Aids: For genetic conditions such as Usher syndrome or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision.
Preventing Night Blindness
While genetic conditions or birth defects that cause night blindness cannot be prevented, maintaining a healthy diet and taking certain vitamin supplements may help prevent or slow the progression of some eye conditions that lead to night blindness. Regular eye exams are crucial in detecting and managing potential causes of night blindness early on.

Frequently Asked Questions
Can night blindness be cured?

If night blindness is due to a reversible condition like a vitamin A deficiency, it can be treated with dietary changes or supplements. For other causes, such as cataracts or myopia, corrective surgery or prescription eyewear may help improve night vision.
How can I improve my vision at night?
A: Some general tips include using anti-reflective coatings on your eyeglasses to reduce glare, keeping your car’s headlights and windshield clean, and avoiding looking directly at oncoming headlights while driving.
