Understanding Night Blindness and Available Treatments

By Dr. Nathan Kluttz 

Nyctalopia, more widely known as night blindness, is a visual impairment that makes it difficult to see in dark or dimly lit environments. It can be likened to trying to navigate in darkness with insufficient light, such as driving with weak headlights or moving around in a blackout with minimal candlelight. 

Spotting the Symptoms of Night Blindness

Night blindness primarily impairs vision in low-light situations, causing difficulties in adjusting to dim lighting and reducing the ability to discern objects or details in the dark. This issue can significantly disrupt routine activities that occur in poorly lit conditions. 

A key area of difficulty for those with night blindness is night-time driving. The reduced visual clarity needed for safe driving in dark conditions is compromised, and the intense glare from bright LED headlights can further exacerbate the issue. 

Causes of Night Blindness

Refractive Errors

Refractive errors, including myopia (nearsightedness) and astigmatism, are often at the heart of night blindness. These conditions alter how light is processed in the eyes, leading to blurred vision and increased glare in low-light settings - two characteristic symptoms of night blindness. 

Ocular Nutrition

Inadequate Vitamin A intake, essential for maintaining good eye health and vision, can also contribute to night blindness. Insufficient vitamin A impairs the eyes' ability to operate effectively in low-light conditions. 

Eye Diseases 

Eye diseases like retinitis pigmentosa, which damage the retinal cells, can lead to night blindness. Additionally, issues with the optic nerve, responsible for transmitting visual information from the eyes to the brain, can also result in night blindness if its functionality is affected. 

Treating Night Blindness

If you are experiencing night blindness symptoms, the first step is to get a thorough eye examination at Grene Vision Group. Our optometrists can determine the cause of your symptoms and suggest the best course of treatment. 

For night blindness caused by refractive errors, corrective lenses such as glasses or contact lenses may be recommended. You may also be advised to increase your vitamin A intake to support eye health. 

If night blindness stems from an underlying eye disease, the treatment will focus on managing the disease's symptoms and slowing its progression. Regular eye exams are essential for effectively monitoring and treating such conditions. 

Preventing and Managing Night Blindness

Proactive measures are crucial for managing and preventing night blindness, particularly if you have a known refractive error or eye disease. Anti-reflective glasses can be beneficial in reducing glare from bright lights, a common issue when driving at night. 

To further protect your vision, maintain a diet rich in vitamin A, incorporating foods like carrots, sweet potatoes, and dark leafy greens. Regular check-ups at Grene Vision Group are also vital for the early detection and treatment of any potential eye issues. To take the first step towards clearer vision, schedule an appointment at Grene Vision Group.


Night blindness significantly affects the ability to see in dark or dim conditions. Understanding its causes, recognizing its symptoms, and knowing the treatment options are crucial for reducing its impact on everyday activities such as driving at night. Proper management of the underlying causes, using suitable eyewear, and adopting healthy lifestyle habits can greatly enhance night vision capabilities.
