Take safety measures to prevent accidents in areas of low light. Avoid driving a car at night, unless you get your eye doctor's approval.
Vitamin A supplements may be helpful if you have a vitamin A deficiency. Ask your health care provider.
When to Contact a Medical Professional
It is important to have a complete eye exam to determine the cause, which may be treatable. Call your eye doctor if symptoms of night blindness persist or significantly affect your life.
What to Expect at Your Office Visit
Your provider will examine you and your eyes. The goal of the medical exam is to determine if the problem can be corrected (for example, with new glasses or cataract removal), or if the problem is due to something that is not treatable.
The doctor may ask you questions, including:
How severe is the night blindness?
When did your symptoms start?
Did it occur suddenly or gradually?
Does it happen all the time?
Does using corrective lenses improve night vision?
