What Is Astigmatism?
Astigmatism occurs when your eye cannot focus a parallel light ray onto the retina, resulting in blurred vision. This happens when there is an irregular curve to the cornea, which makes the front surface of the eye curve slightly off-axis in its plane of focus. This leads to an increase in the diameter of the eyeball, making the retina appear smaller. As a result, objects that you view with this kind of vision will come in small details and may often appear blurry.
Astigmatism is the most common form of vision loss for adults over age 40, and it accounts for more than 25% of all vision loss cases. Because it affects vision for such a large part of the population, many people are concerned about having this condition. In order to learn more about its causes and treatments, please read on.
There are two main forms of astigmatism: standard astigmatism caused by a refractive error. The former occurs when your cornea is shaped irregularly, resulting in a change in the shape of the lens or the retina that makes the eye work in a different way. This causes the front surface of the eye to bend light rays before they reach the retina, resulting in blurry vision. The cause of this type of astigmatism may be due to an inherited trait or due to refractive error. Many people with astigmatism are not aware of this fact, so they go on living a life with poor vision, unaware that treatment is available.

Correcting astigmatism through contact lenses is the most common way to correct the condition. For this method, an optometrist will apply lenses to the patient’s eyes, and adjust them accordingly. Once the eyes are properly adjusted, the optometrist will place the contact lenses in the eyes, and then instruct the patient to wear them. Most astigmatism sufferers can see clearly after wearing the corrective contact lenses for several hours.
Astigmatism can also be corrected by LASIK surgery. In this case, the astigmatism cure requires an extremely strong prescription that covers the entire cornea. Once the cornea is shaped correctly, the laser is used to reshape it, making the vision of the patient better. This method is used mostly for astigmatism caused by irregularities in the cornea, such as an irregular shape. Now if you want the best LASIK surgery for you, then you may contact here:

Another effective way to treat astigmatism is to use glasses. However, this method doesn’t cure astigmatism itself. Glasses only correct astigmatism symptoms, which means that astigmatism may return in the future. A more permanent solution is needed to eliminate astigmatism completely. Contacts solve astigmatism problems while preserving the patient’s vision.
Besides correcting astigmatism, toric irons reduce eye fatigue and improve visibility on cloudy days. The irregular shape of the cornea makes vision get blurred when you’re reading or working outside. Contacts allow your eyes to rest while they focus on the light source. The lenses also reduce glare and sunburns, thanks to their specialized coating.

Astigmatism occurs when the curvature of the eye changes, usually when you age. When this occurs, the light rays that enter the eye don’t reach the retina directly, and the result is blurred vision. Astigmatism can be either near or farsighted, with a tendency to occur more often in people who are middle-aged or older. It can also be hereditary, or the result of a side-to-side difference in the corneas as revealed by the lens of the eye.
Astigmatism can cause other vision problems, such as headaches and eyestrain. Your optometrist will have to take into consideration the patient’s past medical history, in order to come up with a proper diagnosis and suggest the best treatment for astigmatism. And because there are many different types of astigmatism, it’s important to choose a doctor who specializes in treating this particular eye disorder.
