Many people choose to wear contact lenses to correct astigmatism while driving as this eliminates extra light reflection. Mild astigmatism can be corrected by an ordinary gas-permeable lens while others with higher amounts of astigmatism might benefit from special 'toric' soft lenses to fit your eye shape.
Summary. Astigmatism can cause problems with night vision, especially when looking at bright lights. People with astigmatism see different visual effects around lights, such as halos, streaks, and starbursts. Driving at night with untreated astigmatism can be distracting and dangerous.
For those without astigmatism, the cornea and lens are almost completely spherical, like a bowling ball. This permits light to contact the retina without interference for a clear image. The light appears the same way as bright sunlight, but with less glare, and no light sensitivity.
Yes, prescription glasses will help with astigmatism symptoms that affect your night vision. If you see halos, starburst patterns, or blurriness around lights at night, then wearing glasses should eliminate or dramatically reduce these distortions.
Night driving glasses are special glasses that may help you to see better at night while you're driving. They're usually yellow-tinted and don't need a prescription. They often have an anti-reflective coating. Some night driving glasses are also polarized.
Blurred vision is the most common astigmatism symptom. It also makes it hard to see details on objects, like the words printed on a menu in front of you, or letters on a road sign in the distance. Other astigmatism symptoms include: Seeing a glare or halos around lights.
What causes astigmatism? Astigmatism happens when your cornea or lens has a different shape than normal. The shape makes light bend differently as it enters your eye, causing a refractive error. Doctors don't know what causes astigmatism, and there's no way to prevent it.
But if you have astigmatism, the cornea is shaped more like a football, and the light rays entering the eye meet at different points causing blurred vision. At night, or in other low light conditions, the blur gets worse. That's because when the lighting dims, the pupil dilates to let in more light.
Why Is Driving at Night Difficult? If you struggle to see clearly at night when driving or navigating your house, you may have night blindness (nyctalopia). You have night blindness when you struggle to see at night or in dimly lit areas. It may take longer for your eyes to adapt to darker environments.
One natural way to treat astigmatism is to be aware of your head tilting. If you're tilting to one side, try tilting your head in the opposite direction of what feels most comfortable. It will feel uncomfortable at first. Your muscles are used to doing the wrong thing and need retraining.
Avoid glare on TV and computer screens. Place your TV or computer screen where lights do not reflect on the screen. Some people find it easier to work on a computer in a dimly lit room. Special non-glare screens that fit over the computer screen also may help.
Does astigmatism affect night driving? Driving at night is difficult enough for those with perfect vision — but for people with astigmatism, it can be even more difficult. In low light conditions, the blurry vision associated with astigmatism can become worse.
Astigmatism frequently worsens with age. Your cornea can become more irregular due to pressure from your eyelids as they lose muscle tone. Astigmatism generally stays stable until your turn 50. After then, your lens curvature progressively worsens each decade.
Astigmatism does not always require the use of glasses. A person can have slight astigmatism and still see clearly. Similar to the rest of the body, the eyes change over time, so regular eye checks with your local optometrist are of importance.
Astigmatism is a common visual impairment for which many veterans may not realize they could collect disability compensation.
Astigmatism (ah-stig-mah-tiz-uhm) is probably one of the most misunderstood eye conditions. Even the name itself is challenging and is often incorrectly called “stigmatism”. Some people think astigmatism is more serious than it actually is. Astigmatism is not a disease.
Having trouble seeing at night doesn't immediately indicate that you have astigmatism. Just the same, you can have astigmatism and not have issues with night vision. However, if your astigmatism seems to get worse at night, you're not alone!
Blue light blocking lenses
In fact, excessive screen time can even cause digital eye strain, particularly for those with uncorrected astigmatism. Fortunately, blue light blocking lenses can alleviate this discomfort, and make working on your laptop or texting on your phone much more enjoyable.
Dry eye can make your night vision even worse, since the condition dries out your cornea and blocks light rays from landing properly on your retina. You could also have cataracts, which are cloudy or opaque regions on the lenses of your eyes. Cataracts can make you see a glare and halos around lights at night.
Toric or gas-permeable lenses can definitely improve your night vision for driving. If you have at least a moderate form of astigmatism, both of these more rigid lenses can help your astigmatism.
What glasses are best for driving at night? Glasses with a yellow tint and anti-reflective coating are the best for driving at night. Blue light-filtering glasses can also be helpful for those who want to reduce the glare of oncoming headlights.
Your best choice is either clear or yellow lenses. However, we do recommend that you place some serious weight on yellow (or amber) lenses. Even under low-light conditions, yellow lenses can be extremely effective. They increase your depth awareness and enhance contrast when you are driving.
