Night vision difficulties are a common issue experienced by many individuals, especially while driving or navigating low-light environments. The root of the problem lies in the difference in how the eye functions during the day versus at night. In bright conditions, the eye relies on cone cells, which are responsible for detecting color and fine detail. In contrast, under dim lighting, vision depends on rod cells, which lack precision and do not perceive color—resulting in blurred or reduced night vision.<br />Common causes of impaired night vision include vitamin A deficiency (essential for retinal health), uncorrected myopia, cataracts (which cause halos around lights), dry eyes (reducing visual clarity), astigmatism (which distorts light), and age-related decline in the eye’s ability to adapt to darkness. Symptoms of this condition may involve difficulty driving at night, glare or halos around lights, constant need for illumination in dark settings, and slow adjustment when moving from well-lit to dark environments.<br />To improve night vision, it is recommended to undergo a comprehensive eye examination to detect any refractive errors or early signs of ocular disease. Nutritional support with vitamin A-rich foods such as carrots and sweet potatoes is beneficial. Additionally, using night-driving lenses with anti-reflective coatings can help reduce glare. Other preventive measures include minimizing screen use before bedtime, keeping the eyes hydrated with suitable lubricating drops, and regularly cleaning eyeglass lenses.<br />It is important to note that night vision problems are often manageable with appropriate care and treatment. Individuals noticing changes in their night vision are advised to consult an optometrist for proper evaluation and guidance.<br />
