Simply reducing airflow into your face may be all it takes to limit this problem. Keep moving air from vents and open windows away from your eyes. If your eyes get itchy, this may be a sign of allergies. This may be better treated with an allergy drop like Zaditor. [2] X Research source
Sunglasses don’t work so well at night, obviously, but you could try clear plastic safety glasses if you’re more concerned with comfort than fashion. Goggles are probably going too far, and may limit your peripheral vision anyway. The vision benefits of non-prescription night-driving glasses are debatable, but they will help reduce airflow.

Don’t try to put drops in your eyes while driving! Pull over for a minute. While on the subject, never try to adjust, fix, or find a wayward contact while driving. Always stop to make necessary adjustments, and have a backup pair of contacts or glasses handy.
Consult with your eye care professional about trying a different lens type or brand. You can also consider options like glasses or surgery, depending on your vision needs.

[8] X Research source If your contacts improve your vision but are not consistently comfortable, the benefits will be significantly reduced. Clarity and comfort are both important when you are behind the wheel.
If you need corrective eyewear to see clearly, you will likely be required by law to wear them when driving. Otherwise, your driving privileges could be suspended. Some people worry that monovision contacts — where the contact in the dominant eye is calibrated for distant objects, and the weaker eye for close objects[9] X Research source — are problematic for night-time driving. There is little evidence to support this claim, however. [10] X Research source Indeed, if anything, most contact lenses should aid in your night-driving ability by improving your vision. There is a caveat for multifocal lenses, however, which is discussed below. [11] X Research source
Some experts recommend wearing night-driving glasses along with your multifocal contacts to improve visual acuity, while others believe them to be useless in this role. [13] X Research source If you wear multifocal contacts, talk to your prescribing eye doctor, especially if you feel you have any problems with night vision. The best solution may be to simply switch to equivalent anti-glare eyeglasses for night driving. There is no evidence that these hinder low light vision.
Your eye doctor will discuss the right frequency of appointments for you, such as annually or bi-annually. Some contact wearers notice blurry vision at night and blame so-called “night myopia,” but this is not a legitimate medical condition. It is simply more difficult to see at night because of lower light levels. If your vision is noticeably blurry at night, you most likely should have your vision checked and prescription adjusted.

Streaked, smudged, and dirty windshields can cause blurring, clouding, distortions, and glare, so keep yours clean. Dim or cloudy headlights can also limit night vision, so replace dimmed bulbs and clean the outside and inside of the headlamp covers to reduce clouding. If the problem with blurred vision is with your eyes but not your contacts, you may possibly have cataracts. These cannot be cured with eyewear, so consult with an eye care professional for options. A common symptom of early cataracts is increased glare from headlights while driving at night. [16] X Research source
