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 Health Care Provider's Office
Your health care 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 more serious. The doctor may ask you questions, including: - When did the night blindness begin?
- Did it occur suddenly or gradually?
- Does it happen all the time or just sometimes?
- How severe is the night blindness?
- Are you nearsighted?
- Do you have other vision changes?
- What other symptoms do you have?
- Do you have unusual stress, anxiety, or a fear of the dark?
- Does use of corrective lenses improve night vision?
- What medications do you use?
- How is your diet?
- Have you recently injured your eyes or head?
- Do you have a family history of diabetes?
A slit lamp examination may be done.
