The main symptom of astigmatism is blurred vision. This blurriness can lead to squinting, headaches, and even lightheadedness. Most people notice that the blurriness is worse at night. Struggling with nighttime driving is the main reason people seek out treatment.
If you've already been diagnosed with astigmatism, you know this condition can cause blurry vision and make it difficult to see at night, especially when driving. If you're seeing beams of light or light halos when driving at night, astigmatism may be the cause—and you should consult your eye doctor.
If you, sometimes or often, experience dizziness while driving, it is understandable why you may be feeling frustrated. Many people suffer from Binocular Vision Dysfunction (BVD), also called vertical heterophoria, while driving. Some even experience it when they make any form of swift movement.
Even uncorrected astigmatism can cause anxiety when driving. Driving is a complex visual task, therefore the visual system is the first place that should be examined in a patient with driving anxiety.”
There can be a range of reasons why someone might start to experience distorted vision while driving including refractive eye errors, dry eye, low blood sugar levels, and even pregnancy. However, one of the most common is a condition called Binocular Vision Dysfunction – or BVD.
If you begin to experience feelings of vertigo while driving, the best thing to do is immediately pull over and stop driving until the symptoms have passed. However, if you experience these symptoms on a regular basis, it may be beneficial for you to turn to a physical therapist for help.
Someone with astigmatism has an irregularly shaped cornea instead of a round shape. This football shape prevents light from focusing directly on the retina causing blurry, distorted vision, headaches, and eyestrain. At night you will see starbursts or glare around lights making night driving dangerous.
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.
Astigmatism can distort lights in several ways, and instead of a clear image, you might see: Streaky lights. Haloed lights. Blurry lights.
Astigmatism Symptoms
The main symptom of astigmatism is blurred vision. This blurriness can lead to squinting, headaches, and even lightheadedness. Most people notice that the blurriness is worse at night.
Low Vitamin B12 Levels Can Cause Dizziness
“Vitamin B12 deficiency is easy to detect and treat, but is an often overlooked cause of dizziness,” he notes. Ask your doctor about having a simple blood test to check your B12 levels if you're having dizzy spells.
The most common causes of imbalance without dizziness are related to dysfunction of the muscles, joints and peripheral nerves (proprioceptive system), or the central nervous system (brain). People with bilateral vestibulopathy have balance issues but no dizziness if the damage affects both ears at the same time.
Vertigo is the primary symptom of any balance disorder.
If you close your eyes during an episode of vertigo, you'll feel as if you're spinning or falling. Severe vertigo can cause vomiting and stop you from walking.
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.
Yes, glasses can correct astigmatism and dramatically clarify your eyesight. Glasses for astigmatism are fitted with corrective cylindrical lenses that help to properly refract light onto the retina of the eye.
Wearing glasses can't make astigmatism worse, even if they are the wrong prescription. Astigmatism is caused by the shape of the eye's cornea or lens, and glasses can't change those.
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.
Astigmatism occurs when either the front surface of the eye (cornea) or the lens inside the eye has mismatched curves. Instead of having one curve like a round ball, the surface is egg-shaped. This causes blurred vision at all distances.
Astigmatism is often present at birth but it can also develop over time, and most often occurs with myopia (nearsightedness) or hyperopia (farsightedness). The rate of astigmatism significantly increases from 14.3% in the under 15-year-old age group to 67.2% in the age group of over 65-years old.
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.
Several eye conditions are associated with astigmatism. The most common of these being a corneal thinning eye disease known as keratoconus. As the keratoconus progresses, it can cause astigmatism to get worse.
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.
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.
