A refractive defect known as astigmatism happens when the cornea or lens of the eye has an uneven shape, making it difficult to evenly focus light onto the retina. This causes vision to become fuzzy or distorted, both up close and at a distance. Astigmatism can be inherited or can appear later in life.
ASTIGMATISM VS. NORMAL VISION
In order for light to focus equally on the retina, the cornea, and lens must be smooth and spherical. On the other hand, the cornea or lens has an oval or football-like shape in astigmatism, which causes light to focus at various locations on the retina. This causes eyesight to become distorted or blurry, especially at night.
EFFECTS OF ASTIGMATISM ON NIGHT DRIVING
Driving at night might be particularly difficult for astigmatic people. It can be challenging to see clearly due to increased visual disturbances brought on by the glare from approaching headlights and lamps. Astigmatism can make the halos, starbursts, and glare around light sources more intense, which can impair visibility and depth perception.
CAUSES OF WORSENING ASTIGMATISM
A number of reasons might cause astigmatism to get worse over time. Astigmatism can progress due to eye strain, poor eyeglass prescriptions, eye traumas, or certain eye disorders including keratoconus. Regular eye exams are essential to track astigmatism and adjust corrective procedures as necessary.
COPING WITH ASTIGMATISM WHILE DRIVING AT NIGHT
There are a few approaches to think about if you want to improve your astigmatic night driving. First, corrective eyewear such as glasses or contacts that have been prescribed by an optometrist can help with vision correction. Glare can be reduced by lens anti-reflective coatings, and specific lenses for night driving may be useful. Distractions can also be reduced by maintaining clean windshields and regulating interior lighting.
CAN ASTIGMATISM GO AWAY?>
Although astigmatism rarely gets better on its own, it can be efficiently managed with the right vision correction. To correct the abnormal shape of the cornea or lens, prescription eyeglasses or contact lenses can be used. In some circumstances, laser refractive surgery may be a viable alternative to permanently correct astigmatism.
WHAT ASTIGMATISM LOOKS LIKE
Each person’s astigmatism may present itself in a different way. The vision that is hazy or distorted, difficulties reading or focusing on tiny details, eyestrain, and headaches are common symptoms. These symptoms may be more obvious at night because of the increased brightness, haloes around lights, and difficulties accurately gauging distances.
Astigmatism can be problematic due to increased glare and visual disturbances, especially when driving at night. For people with astigmatism, it’s important to seek professional eye care, maintain regular check-ups, and use the proper corrective lenses. Astigmatic people with the proper techniques and visual correction can drive at night safely and comfortably.
