Driving at night used to be no big deal. Now, every approaching headlight feels like a spotlight, street signs seem harder to read, and you may find yourself squinting at things you could swear were perfectly clear during the day.
Sound familiar?
Night vision problems are common, especially as we get older, but they are not something you simply have to accept. Changes in how well you see after dark can sometimes point to an eye condition that needs attention.
Why Is It Harder to See at Night?
Your eyes have to work a little differently in low-light conditions. When the sun goes down, your pupils widen to let in more light, and your eyes rely more heavily on the parts of the retina that help you see in dim environments.
That means vision problems that barely bother you in broad daylight can become much more noticeable after dark. You may notice that things look blurry or hazy, road signs are harder to make out, headlights seem excessively bright, or halos appear around lights. It can also take longer for your eyes to adjust when moving from a bright area into darkness, and objects may seem to blend into the background when contrast is reduced.
And no, turning the radio down probably will not help you see better. We all do it anyway.
Cataracts Are a Common Culprit
One of the most common causes of worsening night vision is cataracts.
A cataract develops when the normally clear lens inside the eye becomes cloudy. Instead of light passing cleanly through the lens, it can scatter. That can make lights seem excessively bright and create glare or halos, particularly when driving at night. Cataracts can also make vision appear blurry, dim, or less colorful.
In fact, difficulty driving at night is often one of the first changes people notice when cataracts begin affecting everyday life.
Your Prescription May Need an Update
Sometimes the solution is less complicated.
Nearsightedness, farsightedness, and astigmatism can all make nighttime vision more difficult, especially if your glasses or contact lens prescription is outdated. Your eyes may compensate fairly well during the day, but lower light levels can make small refractive errors much more obvious.
If the menu board across the room is clear at lunch but mysteriously turns into hieroglyphics after dinner, it may be time for an eye exam.
Dry Eyes Can Make Lights Look Worse
Your tear film helps create a smooth optical surface on the front of your eye. When your eyes are dry, that surface becomes less consistent, which can contribute to fluctuating or blurry vision. That blur may be particularly noticeable around headlights and other bright points of light at night.
Dry eyes can have many causes, so persistent symptoms are worth discussing with your eye doctor rather than simply stocking every cup holder you own with artificial tears.
Could It Be Something Else?
Night vision changes are not always caused by cataracts or a changing prescription. Other eye conditions can affect your ability to see in dim light or create glare, halos, or reduced contrast.
That is one reason an eye exam matters. Your doctor can evaluate more than how many letters you can read on an eye chart and look for changes involving the lens, retina, cornea, and other structures of the eye.
If your night vision changes suddenly, becomes significantly worse, or is accompanied by other new vision symptoms, schedule an evaluation promptly.
Ready to See What’s Going On?
There is a difference between thinking, “Night driving isn’t quite as easy as it used to be,” and actively changing your life because you cannot see comfortably after dark.
Maybe you avoid unfamiliar roads. Maybe you ask someone else to drive at night. Maybe glare makes oncoming traffic genuinely stressful.
If night vision problems are starting to affect your confidence behind the wheel, it may be time to find out why. Schedule an evaluation with The Cataract Surgeons to get a clearer picture of what is affecting your vision and which treatment options may help.
