The human eye is not designed to see well in the dark. Some people may have more trouble than others. This can be caused by a myriad of reasons. The shape of your eyeball can be less conducive to diffusing bright light and make you more sensitive to glare. Your vision, particularly the cones and rods that assist with perceiving light, may not adapt as well to nighttime as they do to daytime light. Or you may be near or far-sighted, which can add to a sense of less visibility when trying to add low light conditions to the mix.
A good way to cope is to make sure you take extra precautions. Avoid driving at night, when possible. Wear night driving glasses when you do drive at night. Make safety a priority, such as driving a bit slower and being vigilant about driving while distraction-free.
