Can cataracts affect night vision?

Cataracts can affect night vision by reducing light transmission, causing glare, and decreasing contrast sensitivity. Visual symptoms related to night vision and cataracts include difficulty seeing clearly in low-light conditions, increased glare, halos around lights, reduced object discernment, and diminished visual sharpness. Cataract surgery can improve night vision by replacing the cloudy lens with an artificial lens.

Night vision and day vision differ primarily in lighting conditions, sensitivity to light, color perception, detail and acuity, peripheral vision, and adaptation time. The eyes and visual system adjust to optimize vision according to the lighting conditions encountered. However, there are certain conditions that can affect them. This article summarizes if cataracts affect night vision, what are its specific symptoms and can cataract surgery improve it. 

Can cataracts affect night vision?

Yes. Cataracts can affect night vision as it causes the lens of the eye to become cloudy. The clouding of the lens in cataracts reduces the amount of light reaching the retina, affecting the eye’s ability to gather visual information in low-light conditions. Additionally, cataracts can scatter light within the eye, leading to increased sensitivity to glare and decreased contrast sensitivity, further impacting night vision. This can also lead to decreased visual acuity, which significantly affects the night vision.

What are the specific visual symptoms related to night vision and cataracts?

Individuals with cataracts often experience difficulty seeing clearly in low-light conditions, such as at dusk or during nighttime. They may notice increased glare from oncoming headlights or streetlights, halos around light sources, reduced ability to discern objects or people in dimly lit environments, or a general decrease in visual sharpness.

It’s important to note that these symptoms can vary in severity as per the patient’s condition and may worsen as cataracts progress. 

Can cataract surgery improve night vision?

Yes, cataract surgery is an effective treatment for cataracts and can significantly improve night vision. During the surgery, the cloudy lens is removed and replaced with an artificial intraocular lens (IOL), which allows for clearer vision. Many individuals report enhanced night vision and improved ability to see in low-light environments after cataract surgery.

It is important to consult with an eye care professional for an accurate diagnosis, evaluation, and appropriate treatment options if you are experiencing night vision difficulties associated with cataracts. They can provide personalized advice and guidance based on your specific situation.
