Night Blindness Symptoms And Treatment

Our today topic is night blindness symptoms,causes and treatment of night blindness.Night blindness is a disorder of visual impairment affecting 1 person every 10,000 people. Night blindness, also known as chicken poultry, is known as the problem of not seeing clearly at night or in dim lighting, and there are many reasons. As people affected by night blindness do not see clearly, they have difficulty moving and driving in the evening and at night. Night blindness can also be hereditary as it may appear later on.

Night Blindness Symptoms
Weak or blurred vision in dimmed environments or during evening and night time
Long vision loss after exposure to bright light
Visual loss stages can take a long time, either transiently or gradually.
Permanent eye brow can be seen.

Causes And Treatment Of Night Blindness
Night blindness may indicate much more dangerous health conditions, depending on the underlying cause. Here are the most common reasons for these reasons and the treatment methods depending on these reasons:

1. Untreated Myopia

Myopia can cause night blindness in some cases. The myopia is caused by the expansion of the eyeball. This causes vision problems in the dark, blurred vision, and dim lighting because of poor retinal incoherence.

Myopia Treatment: Myopia is treated with corrective lenses. In some cases, refractive surgery may be needed. LASIK surgery is an effective choice for this. Another option is PRK surgery.

2. Glaucoma  Disease and Eye Disease Printing Drugs

Glaucoma (condition that causes damage to your eye’s optic nerve) disease pressures the eyes, which can also cause blindness by affecting the optic nerves. This disease can also lead to night blindness in its early stages.

Glaucoma medications can also constrict eye babies. The narrowing of the eye baby reduces vision by reducing the light entering the eye, which may result in night blindness. Since glaucoma can cause permanent blindness, early symptoms should prompt the doctor.

Glaucoma Disease Treatment: Glaucoma disease can be effectively treated by clearing the eye drainage mechanism by surgery and laser treatment. Some drugs may be given by the doctor to reduce the pressure around the eyes, but surgery is the most effective treatment. Laser trabeculoplasty(laser treatment for glaucoma), trabeculectomy, and surgical implants are procedures that reduce the perineal pressure.


Cataract is another problem that causes night blindness. Cataract leads to gradual blurring of eye lenses, which weakens vision.

Cataract surgery : cataract surgery completely removes the problem. In operation, a phacoemulsification method is used to insert a pulsed ultrasonic spindle and the blurry layer in the eye is cleaned. Through this shaft, a puddle causing blur in the eye is removed. At the last stage, a spherical lens is placed.

4. Retinitis Pigmentosa

Retinitis pigmentosa is a genetic disease that directly causes night blindness. As the disease progresses, vision disappears completely. Usher’s syndrome leads to night blindness indirectly by causing retinitis pigmentosa with loss of hearing.

Retinitis Pigmentosa Treatment: This disease is completely untreatable, but progression to vitamin A supplementation and surgery can be controlled. The exact treatment of the disease has not yet been found, but retinal transplants to be made in the future may provide definitive treatment of the disease. This disease is recommended by doctors to protect their eyes from ultraviolet rays sunglasses.

5. Vitamin A Deficiency

A lack of vitamins is the main reason for night blindness. The lack of vitamins A is affected by retinal function and visual perception is weak.

A Vitamin Incomplete Treatment: Vitamin supplementation is provided regularly at night blindness, which is caused by lack of vitamin A. Foods rich in vitamin A such as carrots, potatoes, dried apricots, tuna fish, and mangos are to be consumed continuously.

6. Zinc Deficiency

Zinc mineral has an important role in the vision mechanism by working with vitamin A. Zinc deficiency can lead to visual impairment and night blindness.

Zinc Incomplete Treatment: Beef, hard-shelled fruit, poultry meat are very rich in zinc mineral.

7. Diabetes (Diabetes)

The increase in the amount of sugar in the end of diabetes can lead to night blindness. Visual loss is the most important symptom of diabetes.

Diabetes Mellitus Treatment: Diabetes mellitus can be diagnosed at an early stage and treatment with insulin injection can help to control the disease. The possibility of loss of vision on this side can also be minimized. Treatment also includes the use of glasses and surgery in more severe cases.

8. Exposure to sunlight

Exposure to sunlight for extended periods of time can also lead to temporary night blindness. This may take up to 1-2 days. Prolonged exposure to sunlight can also lead to yellow spot disease and cataracts.

Treatment: Night blindness can usually last up to 1-2 days. During this time it is very important to limit the movements and to relax the eyes. Sunglasses and wide-edge hats also help protect the eyes.

9. Keratocon

The cornea is called keratokon when it is turned from a normal domed or spherical shape to a conical shape. This results in the collagen fibers failing to hold the cornea in the correct position in the correct position. The result is diminished vision in low light, increased sensitivity to bright light, and eye irritation.

Keratoconus Treatment: There are different treatments according to the severity of the disease. The use of soft contact lenses and rigid gas-permeable lenses to correct the shape of the cornea is an important treatment option. In more advanced cases, surgery may be considered.
