Night-Blindness: Symptoms, Causes, and Treatment

Night Blindness

Night blindness is a condition in which people face difficulty with their vision in comparatively low light. It is an indication of numerous eye diseases. Night blindness is a condition which can exist from birth or can be caused by damage. Lack of vitamin A is also a major reason of night blindness. It can be described as an inadequate adaptation to darkness.

Symptoms of Night Blindness

The following are the symptoms of night blindness:

  • Vomiting
  • Blurry or cloudy vision
  • Sensitivity to light
  • Difficult to see into the distance
  • Eye pain
  • Nausea
  • Headaches

Causes of Night Blindness

There are a number of eye conditions, vitamin deficiencies and chronic disease that can affect your night vision which includes the following:

a) Age: With the increased age our pupils don’t dilate in dark as much as they should, this is the reason that the amount of light that enters in our eyes gets reduced. The cornea also becomes less clear with increased age and the amount of glare to view the objects will reduce which can make it difficult to distinguish between objects in the night.

b) Glaucoma: This is a cause in which the build-up pressure in the eye will affect peripheral vision and it results in difficulty to see what is going around you which is very dangerous while driving at night.

c) Cataracts: This is a cause in which the clouding of the lens of the eye blurs the field of the vision and you face difficulty while viewing the objects clearly. Cataracts may inhibit your night time driving vision as many people with cataracts eye condition describe much difficulty with halos and glare from oncoming headlights.

d) Presbyopia: This is the cause of night blindness which develops with age and can make focusing and adjusting to light changes more difficult. It makes driving in the night or driving in rain difficult especially for older people.

e) Diabetic retinopathy: This is a condition in the back of your eye which is caused by diabetes. Diabetic retinopathy can cause a vision loss and is the leading cause of retinal blindness in adults between the age group of 20 to 65 years.

f) Nutritional deficiency: Night blindness can be caused due to the deficiency of vitamin A and Zinc. Although it’s rare that not getting Vitamin A in your diet could affect your night vision. Zinc helps the body to absorb vitamin A so that without zinc, vitamin A is not as effective.

g) Retinitis pigmentosa: This is an uncommon genetic disorder in which dark pigments are collected in your retina which can create tunnel vision. This is a condition which mainly affects the people under the age of 30 years and night vision gets worse.

h) Sun Exposure: Sun exposure can temporarily affect the night vision which lasts up to two days. Wearing sunglasses will protect you against the ultraviolet rays and will prevent temporary night blindness due to sun exposure.

i) Choroideremia: This is a very exceptional disease that results in progressive vision loss especially in male members. Night blindness is the first common symptom in this disease during the patient’s childhood.

How to treat the Night Blindness?

Non-Surgical Treatments to treat the night blindness are as follows:

a) Herbal remedies: Herbal remedies such as phytotherapy plays a major role while treating the cause of night blindness as this involves using a number of plants and their extracts which enhance the eye’s capability to see in the dark.

b) Internal use preparation: This is a non-surgical procedure in which blueberries are helpful in capturing the images in dim light and conditions such as glaucoma or myopia.

c) Proper nutrients: According to the study, the night blindness can be improved by taking nutritious diet which is rich in plants that arouse the amalgamation of light on the retina. It has been found that eating vegetables which contain vitamin A, and other antioxidant plant food can result in prevention or slowdown of the condition.

Surgical treatment

In case, the non-surgical treatments are failed to prevent the eyes then the last option is the surgery which will be recommended by the eye surgeons at the hospitals under We Care India only in severe cases.

They recommend the surgery like LASIK in which the shape of the cornea will be changed to improve the vision. The surgeons perform the other types of surgery which may aim to remove a cataract from the eye or to release pressure in the eye for treatment of glaucoma.

According to the study, in some of the cases, night blindness may not be treatable. As per research retinitis pigmentosa currently has no effective treatments. This can only be treated by certain eye devices and therapy services which may improve the symptoms of night blindness and also improve the quality of life.

Your eye surgeon recommends taking precautions to lower some of the risks that cause night blindness which means they ask you to avoid driving at night or avoid having to navigate or move around in the dark wherever it is possible.

Effective treatment for night blindness can significantly improve your vision at night, as well as other symptoms of the underlying condition causing it.
