What You Should Know About Night Blindness

If you don’t see well while driving at night, there’s a chance you have night blindness. Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. It’s not considered an eye disease, but rather a symptom of an underlying problem.  

Our eye doctors can help diagnose, manage and treat your night blindness so that you can enjoy being out at night again. 

Here are 4 things you should know about night blindness:

Causes of Night Blindness 

The inability to see well at night can be the result of a condition such as:

Vitamin A Deficiency — Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness. 

Cataracts — A buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.

Diabetic Retinopathy — Damage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.  

Glaucoma — This group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both glaucoma and the medications used to treat it can cause night blindness. 

Myopia — Also called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.

Keratoconus — An irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.

Retinitis Pigmentosa (RP) — A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.

Usher Syndrome — This genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.

Symptoms of Nyctalopia

Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors. 

Symptoms of Night Blindness Include:

  • Reduced contrast sensitivity
  • Difficulty seeing people outdoors at night
  • Difficulty seeing in places with dim lighting, like a movie theater
  • Trouble adapting to the dark while driving
  • Excessive squinting at night 
  • Trouble adjusting from bright areas to darker ones 

Treatments for Night Blindness

Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery. 

If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision. 

Prevention

While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.

How Can My Child’s Myopia Be Corrected?

Myopia, or nearsightedness, is one of the most common eye conditions affecting millions of people around the world.

Myopia is a refractive error in which the eyes are unable to focus clearly on images or objects. This results in blurry vision when looking at something at a distance, such as people walking down a street, a school board, or even the TV. However, images that are closer can be seen more clearly. Children with uncorrected myopia tend to experience eye strain, eye fatigue, or headaches in an effort to see images in the distance clearly.

Fortunately, eyeglasses or contact lenses work wonders to correct vision. In this text, we’ll discuss both glasses and contacts as options for myopia correction.

 

Methods of Myopia Correction

Contact Lenses

Contacts can be a great choice, especially for physically active children or teens who don’t want to worry about breaking or misplacing their eyeglasses.

Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. We offer a range of brands of soft contact lenses, such as daily disposables and extended-wear disposables. Speak with Dr. Matthew Anderson to determine whether your child is ready for contact lenses.

Prescription Glasses

Glasses are a popular choice among our younger patients. Choosing from an array of styles makes the process not just fun and exciting, but allows the child to be an active participant in selecting eyewear, which, in turn, increases the likelihood that they’ll actually wear them. We offer strong, flexible and resilient frames which both look great and are feel comfortable.

The optician can customize the lenses with additions, like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun.
