Night driving is not a big deal for many people, except if you have astigmatism. This condition is very common, and you may even not know that you have it. Hence, what’s this vision problem, and what people actually see?
In this article, we will explain this condition and how can be fixed.
What Is Astigmatism And Why It Makes Night Driving Difficult
Astigmatism is a relatively common visual disorder in which refracted rays are not focused in one, but in several points. Astigmatism can occur in both short-sighted and far-sighted people and is mainly associated with an irregular shape of the cornea.
The normal cornea has the shape of a section of a soccer ball where all its meridians have the same curvature. The meridian is a line that connects two points at opposite ends of a circle. In astigmatism, the cornea has the shape of a section of a rugby ball where different meridians have different curvatures.
Because of this, people who have it lose a single focus, and their vision is diffracted in many different rays. This results in seeing objects stretched, blurred, and distorted. Astigmatism is very often inherited, occurs in childhood, and can change throughout life.
Astigmatism is not anything serious and it can be corrected quite easily. Usually, your eye doctor will proscribe eyeglasses or contact lenses. You can also get refractive surgery to fix the problem.
Common symptoms of astigmatism are:
- Tilting your head while you’re reading, watching television, etc.
- Rapid eye fatigue
- Frequent headaches
One thing that bothers most people with astigmatism, is driving at night. This is because lights shift and bend causing a distortion. Moreover, if you are night driving and it’s raining, it’s even more difficult. Mixing lights and the rain falling on the pavement in the dark can be quite blinding for people with astigmatism. Some people have to pull off when this happens because they can’t see well.
To get the idea, what astigmatism looks like when you drive at night one twitter user shared a picture. After this image reached a large number of people, some of them realized that they have this condition. If you have the same problem, we suggest to make an appointment with the ophthalmologist and get your eyesight checked.
Most people with this vison problem have normal lives. So, if you are among these people, you can easily fix the problem. However, you must react in time.
