Treating Astigmatism Successfully with Colored Contact Lenses
Astigmatism, it is an eye defect or problem that causes blurred vision. It occurs due to the inability of the eye optics that fail to focus on an object that enables retina to produce a clear vision. The reason behind it might be an uneven or toric curvature of the lens or cornea. According to recent studies, nearly 3 out of 10 children aged between 5 to 17 suffer with astigmatism and the rate might see a jump in the near future. So, it is very important to know, why it happens and the best way to deal with it.
What causes astigmatism?
It is often caused by an irregular shaped cornea. If the cornea have a football like shape instead of symmetrically round shape (like a baseball), one meridian becomes much more curved than the other one that is perpendicular to it. This gives rise to astigmatism in the eye. Sometimes, it is also happen due to the shape of the lens inside the eyes and that is so called lenticular astigmatism.
Types of astigmatism:
Generally, we experience 2 types of astigmatism (based on axis of the principal meridians) and 3 types of astigmatism (based on focus of the principal meridians).
Based on focus:
Myopic astigmatism: When both or one of the focal lines is located in front
of the retina.
Based on axis:
Regular: If the principal meridians are at the right angles.
It could be detected during a routine eye check-up, by using the same instruments and techniques used to detect the farsightedness and nearsightedness. An eye specialist could estimate the amount of astigmatism you have by doing retinoscopy and prescribe the best treatment options available.
Astigmatism correction options:
Astigmatism, such as farsightedness and nearsightedness, could be corrected using Colored contacts for astigmatism, or refractive surgery. But, the best treatment option depends on a number of considerations including your eye health, lifestyle, and refractive status. However, professionals recommend certain lenses like Sharingan contacts that often enable sufferers to attain better visual acuity as compared to the eyeglasses.
