If night blindness is caused by congenital reasons, then staying up late generally does not significantly worsen it. If it is caused by acquired eye abnormalities, staying up late will noticeably exacerbate the occurrence of night blindness. Additionally, if it is caused by a deficiency in vitamin A, one should rest properly, reduce close-range activities, avoid staying up late, and supplement with foods or medications containing vitamin A. If the night blindness is due to eye-related causes, active treatment and regular follow-ups are recommended. If it is due to congenital reasons, currently there are no particularly effective treatments available.

Can night blindness see clearly during the day?

Night blindness is mainly due to two types of cells on our retina: cone cells and rod cells. Rod cells are responsible for vision at night, while cone cells are responsible for vision during the day and are crucial for sharp vision. In cases of night blindness, there are issues with the rod cells, but patients also have problems with their cone cells. Therefore, not only is their nighttime vision unclear, but their daytime vision is also worse than that of an average person. Although they can see during the day, the clarity is impaired. This condition is primarily due to a genetic anomaly, often involving a chromosomal abnormality. It is recommended that patients supplement with B vitamins, such as lutein.

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.

What will happen if night blindness is not treated?

Night blindness, if left untreated, can progress slowly in some cases and more rapidly in others, potentially leading to blindness quickly. Therefore, it is recommended to visit a hospital for diagnosis and targeted treatment if night blindness occurs. Night blindness refers to the blurriness or even complete inability to see in low light conditions or at night, causing difficulty 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 genetic factors. Patients are born with a deficiency in synthesizing rhodopsin, which leads to night blindness. It is recommended to supplement with Vitamin A as per medical advice, though the treatment effectiveness for congenital night blindness is generally poor, and gene therapy is considered a direction for the future. Acquired night blindness is often caused by diseases intrinsic to the eye, and it is advisable to actively treat the primary disease. Temporary night blindness is mostly due to a lack of Vitamin A in the diet or due to certain digestive system diseases that affect the absorption of Vitamin A; hence, it is recommended to supplement Vitamin A as advised by a doctor.

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.

Is night blindness related to myopia?

Night blindness generally has little to do with myopia. Night blindness can be divided into congenital night blindness and acquired night blindness, caused by retinal dysfunction. Myopia makes distant objects appear blurry and near objects clear, primarily due to changes in the eye's axis. Night blindness does not involve changes in visual acuity or the eye's axis. Once night blindness occurs, one should actively seek an ophthalmological examination and receive proper treatment. Currently, the treatment for myopia mainly includes corrective glasses, orthokeratology (corneal reshaping therapy), and surgical treatments.
