Well, there indeed are some effective ways to improve night vision. I also need to drive in night sometimes, so this is a problem that I concerned very much too. There are two kinds of cells in eyes, rod and cone. Cone cells are good at color detection while rod cells are good at catching movement and they are better in dim light. So to improve the night vision, we need to use our peripheral vision, by glancing sideways instead of staring. Practice makes perfect. After again and again practices, we might found our night vision improved. Have our eyes prepared for dark light could help improve night vision too. Before entering the dark circumstances, close eyes or squint or put your hands on eyes to help them get used to the dim light. The rod could get active and make your vision in dark better. There are some other points you need to note, smoking decreases night vision. Take some vitamin A supplement and some other vitamins and mineral which are benefitial to eye health and vision, for example carrots, carrot juice and some nutrition like lutein, ginkgo biloba, bilberry, zeaxanthin and etc. while driving in night, if you feel bad night vision, you could have a piece of sugar which could take effect soon because night vision is dependent on blood sugar level actually.
