Do you have trouble seeing clearly in dim light? Does it take you tremendously long to adapt to a dark room when you have just spent some time in a brightly lit room? If so, you may have been experiencing night blindness also known as Nyctalopia.
Although night blindness does not cause complete vision loss, it impairs the ability to see in low light. The eye condition could interfere with driving during the night, discerning facial features in poorly-lit rooms, as well as walking about the house in low light.

Symptoms of night blindness
The chief symptom of night blindness is an impaired sight during the night. However, other symptoms may also indicate the presence of the eye condition. These include:
- Difficulty in discerning the shape or placement of objects in a dark room
- Taking a long time to adjust vision in a dark room after turning out the lights and/or walking out of a brightly-lit room
- Impairment of depth perception in poorly-lit areas
In most cases, these primary symptoms are accompanied by other symptoms such as:
- Sensitivity to light
- Cloudy vision
- Eye pain
Causes of night blindness
Night blindness is a result of several eye conditions, many of which could be treated. Below is a list of eye conditions that cause night blindness:
Cataracts are a commonly diagnosed eye problem/ external sign related to the process of ageing. Cataracts are basically clouding of the lens, causing vision impairment. As the age increases, protein clumps are formed in the lens of the eyes. The protein clumps become thicker over a period of time, clouding the natural lens, and impairing vision by limiting the amount of light that enters the retina.
Night blindness is one of the symptoms of Cataracts. Other symptoms of the eye condition include blurry vision, double vision, sensitivity to glare, and impairment of colour vision.
Glaucoma is another age-related eye condition that causes night blindness. The occurrence could be attributed to the increase of intraocular pressure (fluid pressure inside the eyes). Several factors could lead to an increase in intraocular pressure; these include eye infection, genetics, and blockage of a blood vessel inside the eye.
Apart from night blindness Glaucoma causes other symptoms such as cloudy vision, redness in the eyes, seeing halos around lights, and tunnel vision (narrowed vision).
Diabetic Retinopathy occurs when blood vessels leak inside the retina. The leakage leads to changes in vision. Diabetic Retinopathy may result in permanent vision loss, if not addressed properly.
Night blindness is a symptom of the above eye conditions along with other symptoms such as seeing black spots, floaters, blurry vision, and loss of central vision. Disha Eye Hospitals provide advanced diagnosis and treatment for Diabetic Retinopathy in Kolkata.
Diagnosis of night blindness
While conducting a diagnosis of night blindness, eye doctors look for determining factors such as:
- Lowered visual acuity in low light
- Presence of risk factors of night blindness-causing eye problems
- Past medical history of Vitamin A deficiency
- Family history of vision loss
- Retinal vascular attenuation
