Astigmatism affects your cornea and lens. The cornea and the lens are normally circular like a football, the cornea and lens of astigmatism. This curvature impacts the eye’s light gathering and processing.
The cornea collects light and sends it to the retina when we usually see it. The cornea’s spherical shape contains light and allows it to flow to the retina easily. The cornea’s shape causes it. This generates a halo or glare around the retina’s picture, making it difficult to focus and see clearly. It also makes a difference in vision astigmatism at night vs normal.
The Effects of Astigmatism on Vision
The cornea and lens are responsible for bending light and focusing it on the retina, a light-sensitive area at the back of the eye that provides the ability to see. Astigmatism is a condition in which the cornea or lens is irregularly formed. The surface may be shaped more like a football rather than a circle. Consequently, light cannot concentrate appropriately on the retina, resulting in hazy and distorted vision.
The dilation of your pupils to allow more light into your eyes occurs during the night, which causes difficulties with glare and halos surrounding street lights and headlights.
A small percentage of instances with astigmatism are moderate enough that no treatment is required. Mild to severe cases almost always need some form of therapy to see properly again, which may involve glasses, contacts, or corrective surgery.
Driving at Night While Having Astigmatism
People with astigmatism have particularly impaired night vision. When you have average eyesight, the pupil dilates at night to enable more light to enter. This permits the cornea to accept more light, allowing the retina to form a more precise visual image.
Unfortunately, if you have astigmatism, allowing more light into the cornea causes your eyesight to suffer more. The more light permitted to pass through the cornea, the more light that is dispersed. Because of the dispersed light, it is considerably more difficult for the retina to comprehend the vision.
Those with astigmatism tend to experience the most difficulty when driving at night. Traffic lights and other bright signs might make it extremely difficult to focus their rays properly and drive safely.
Night Driving with Astigmatism Solutions
You don’t have to drive while squinting or closing one eye if you have astigmatism. There are ways to improve your night vision so you can keep your long-haul trucking work options open.
Lenses
Using corrective glasses is one of the simplest and least invasive techniques to correct astigmatism. They help reduce glare and halos caused by your illness by changing how your eyes collect light.
You can also wear contacts. As with eyeglasses, contact lenses are put over your eye’s surface and give visual improvement through a prescription.
Surgery
Surgical intervention is a permanent remedy. Astigmatism surgery is accessible in four forms. Depending on your astigmatism and other health issues, you may prefer one approach over another.
Takeaway
An eye exam and discussion with your eye care professional can help you select which surgical option is appropriate for you.
