How to Help Night Vision

Do you have difficulty seeing at night?Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. Drs. Dianna Leong and Andrew Chan want you to clearly see 24/7. 

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 build up the rhodopsin within rod receptors in the retina.  It also reduces dry eye by improving tear function to keep the cornea clear.   Although uncommon in North America, deficiency of Vitamin A can induce night blindness. 

CataractsBehind the iris is a natural crystalline lens that is transparent when you are born, but gradually gets more cloudy with exposure to UV light, certain medications, smoking, injury and other causes.  Less light gets transmitted to the retina, and this commonly causes complaints of poor night vision.  

Diabetic Retinopathy — Damage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.  Particularly if laser PRP is done to tear the retina to avoid further diabetes damage, night vision becomes more difficult.   

Glaucoma — This group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Glaucoma reduces peripheral vision which also results in problems with night vision.  

Myopia — Also called nearsightedness, myopia makes distant objects appear blurry.  Pupils get larger in the dark, reducing depth of field and increasing blur and 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 may be 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. Your eye doctor can assess for these conditions in a routine eye exam.  

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 Eyefoods; 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?

At Foresight Eyecare, we help children like yours achieve clear and comfortable vision, so they can succeed at the important things in life.

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. In some cases of very high myopia, contact lenses can offer clearer vision than glasses.

Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. There are several types, including: soft contacts, daily disposables, extended wear, and rigid gas permeable (hard) lenses. Navigating through the differences between them can be daunting. Fortunately, if you’re located in Calgary our eye doctor will be happy to guide you. Speak with Dr Leong 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 fun and exciting! Allowing the children to be active participants in selecting their eyewear increases the likelihood that they’ll actually wear them. There are strong, flexible and resilient frames which look great and are comfortable too.

The optician can customize the lenses with additions and upgrades like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun. For those requiring vision correction for distance and near, we also offer bifocal or multifocal lens prescriptions.
