If you are having trouble seeing to drive at night, it could mean you need glasses. This is especially true for those who are nearsighted. It could also indicate that you have cataracts or another eye condition, but it is essential to consult with your doctor if you’ve noticed difficulty seeing at night.
Night vision loss and night blindness are both caused by a disorder of the cells in your retina, affecting how you see dim lights.
How do I Know I Have Night Vision Loss?
To determine whether you are experiencing night vision loss or blindness, there are a variety of symptoms to look out for. Symptoms of night vision loss include:
- Halos/rings around lights such as street lights or oncoming traffic lights.
- Blurry night vision, specifically reading or close viewing.
- Experiencing sensitivity to glare or light.
What Causes Night Vision Loss?
Night vision loss can be caused by a variety of factors including:
- Cataracts. This is a clouding of the natural lens of the eye and is a result of the natural aging process, making it common in people in their 60s.
- Glaucoma. This condition negatively affects your overall vision, including your night vision. If you have glaucoma and are experiencing loss of side vision, sensitivity to light or blurred moving objects, you may want to consider avoiding driving day or night.
- Genetic defects. A genetic condition such as Usher syndrome can affect your night vision.
- Vitamin A deficiency. This deficiency is not common in the developed world but may still be a possibility. If you are lacking vitamin A, you can improve your levels by taking vitamin A daily.
How to Prevent Night Vision Issues
In cases where a congenital disability or genetic condition is causing night vision loss cannot be avoided. In many cases, eating a balanced diet can help you in your efforts for preventing night vision loss. By incorporating foods that are rich in antioxidants, vitamins, and minerals, as well as high levels of vitamin A, could help you reduce the risk of night vision issues.
Food such as sweet potatoes, carrots, pumpkins, milk, and eggs are all great options to add to your diet that may help your eye health. If you are noticing that your night vision is deteriorating, it is important to know your limitations for safe driving and to see your optometrist as soon as possible to determine the issue and begin treatment.
