Causes: Vitamin A deficiency: This vitamin is very important for eye health, and a deficiency can lead to vision problems, including night blindness. Macular degeneration: A disease that affects the central part of the retina, leading to loss of central vision and, therefore, may increase difficulty seeing in low light. Diabetes: Can lead to retinal problems that affect vision in the dark. Aging: As you age, the eye's ability to adapt to low light may become less effective. Treatment: Vitamins: Taking vitamin A supplements can help with some conditions associated with vitamin A deficiency. Monitoring other medical conditions: Diabetes or other eye conditions can cause night blindness. If you suspect you may be suffering from night blindness, it's best to consult an ophthalmologist for an accurate diagnosis and appropriate treatment.
