Night blindness is not related to using mobile phones. Night blindness can be caused by several reasons, with the common ones as follows:

First, it can be caused by a deficiency in vitamin A, commonly seen in patients with long-term unbalanced diets and malnutrition. Vitamin A is an essential raw material for the synthesis of photosensitive substances in the retina. A deficiency in vitamin A can lead to abnormal retinal function, causing night blindness. This can be treated by taking vitamin A capsules orally or by consuming foods rich in vitamin A, such as animal liver and carrots.

Second, it can be caused by retinitis pigmentosa, which is related to congenital developmental abnormalities. Currently, there are no effective treatments available.

Third, it can be due to advanced glaucoma, where surgical treatment to lower eye pressure is needed to prevent and slow the progression of the condition.

What should I do if night blindness is afraid of sunlight?

People with night blindness, who are sensitive to sunlight, can wear sunglasses when going out, and should actively seek treatment for night blindness. Night blindness refers to the blurriness or complete inability to see in dim light or at night, which makes mobility difficult. Night blindness can be categorized into congenital night blindness, acquired night blindness, and temporary night blindness. Congenital night blindness is mostly related to hereditary factors, where patients are born lacking the ability to synthesize rhodopsin, leading to night blindness. It is recommended to supplement vitamin A in appropriate amounts, and gene therapy is a potential treatment direction. Acquired night blindness is generally caused by diseases of the retina or other eye conditions, and it is recommended to actively treat the primary disease. Temporary night blindness is often due to a lack of vitamin A in the diet or due to some digestive system diseases affecting the absorption of vitamin A. It is advisable to supplement vitamin A as per medical advice and actively treat digestive tract diseases.

Will night blindness lead to blindness?

Night blindness first requires determining the cause of your condition. If it is due to a deficiency of vitamin A leading to night blindness, supplementing vitamin A can alleviate the symptoms, and the night blindness will disappear. However, if the night blindness is caused by retinitis pigmentosa, as this condition progresses with age, the symptoms of retinal pigment degeneration worsen and the retinal-caused night blindness will gradually intensify, eventually there is a possibility of blindness. It is essential first to determine the specific cause. Some people may experience a rapid progression of the disease, but others with retinitis pigmentosa, or such symptoms of night blindness, may not be very severe. They could maintain useful vision throughout their lives, which mainly depends on the type and severity of the genetic mutation and the specific causes.

Can mild night blindness be cured?

Night blindness is a common ophthalmic disease caused by many factors. Its main symptom is difficulty seeing in dim environments, and it takes a longer time to adapt when moving from bright to dim surroundings. For mild night blindness, it is important to first identify the specific cause. Different causes lead to different treatments and outcomes. For example, night blindness caused by a deficiency in Vitamin A can be completely cured by taking oral Vitamin A capsules or by consuming foods rich in Vitamin A such as carrots and animal liver. Night blindness caused by malnutrition of the rod cells in the eye is incurable. For night blindness resulting from advanced glaucoma, treatment can delay and control the progression of the disease, but cannot reverse the damage already done to vision.

Can night blindness be improved by wearing glasses?

Generally speaking, it is difficult to improve night blindness by fitting glasses. If the patient already has tunnel vision, they can try wearing special glasses to enhance the visual quality of the remaining vision. Night blindness refers to blurred vision or even complete inability to see in the dark or dimly lit environments, causing difficulties in movement. Night blindness can be categorized into congenital night blindness, acquired night blindness, and temporary night blindness. Congenital night blindness is mostly related to congenital genetic factors, where patients are born lacking the function to synthesize rhodopsin, leading to night blindness. Currently, there is no specific treatment, but it is advisable to supplement vitamin A as per medical advice. Acquired night blindness is often due to diseases of the eye itself and it is recommended to actively treat the primary disease. Temporary night blindness is mostly due to a lack of vitamin A in the diet, or diseases of the digestive system that affect the absorption of vitamin A, and it is recommended to supplement vitamin A as per medical advice and treat digestive tract diseases, which can mostly improve the condition.
