Common Eye Conditions
Astigmatism: What You Need To Know
Astigmatism falls under the ‘refractive errors’ category with either myopia (near-sightedness) or hyperopia (far-sightedness). These refractive errors entail your eye(s) ‘ inability to properly bend light onto the retina to form a clear image. Thus, you may see wavy and blurry images of objects, especially distant ones.
The eyeball is usually perfectly round, but in the case of astigmatism, the eyeball might be egg-shaped. This is a common and highly treatable condition with minor chances of any long-term effects.

Symptoms Of Astigmatism

- Squinting often or perhaps, sensitivity to light (not considering the immediate exposure to sharp or bright light)
- Eye irritation
- Eye strains
- Sleeping difficulties
Causes of Astigmatism
Astigmatism does not pose any high-risk in the form of any chronic health condition and can normally occur at any age.
- Eye surgery
- Eye injuries
- Keratoconus is a condition that causes the thinning of the cornea.
Treatments for Astigmatism
Mild to chronic astigmatism requires treatments. There are a bunch of options you can go for to treat your astigmatism condition.
Contact Lenses and Eyeglasses
Requiring frequent cleaning, some special corrective lenses can treat your astigmatism. The need to wear them in direct contact with the eye compels you to opt for only the best in the market. These are often expensive, so you need proper safeguarding techniques to preserve their quality.
On the other hand, prescriptions might suggest wearing eyeglasses. They focus on the correction of one or both eyes via the use of cylindrical lenses.
LASIK, LASEK, or other types of laser surgeries can treat astigmatism. The ideal aim of laser surgery is to reshape the cornea (lens) in your eye(s). There are numerous options when it comes to laser surgeries. Nevertheless, it is essential that you do not have any previous underlying conditions about your eye health (cornea scars or tissue damage).
This is a temporary fix for the uneven or cone-shaped cornea. It is necessary that you wear a rigid contact lens for limited periods throughout the day. People opting for Ortho-K often wear it overnight. Nonetheless, it is not a permanent fix.
