When you visit your eye doctor, there are probably a few common terms heard around the office that you may or may not know. Myopia, presbyopia, and others are the medical terms for different types of refractive vision errors. Perhaps the most frequently heard one, that many may not truly know what it means, is astigmatism.
Nearsightedness (myopia), farsightedness (hyperopia) and astigmatism are the three most common types of vision errors and each has to do with the shape of the eye and how light is focused. Learning what each error means exactly can help you better understand the options available for correcting or curing the error.
Common Refractive Vision Errors
Myopia – when the cornea has too much curvature or an elongated shape. This causes a person to be unable to focus light properly from objects that are far away; hence why it is commonly referred to as nearsightedness.
Hyperopia – otherwise known as farsightedness, happens when the cornea does not have enough curvature, or the eye is too short in shape. The lack of curvature causes the light from close objects to focus improperly on the retina, which results in blurry up close vision.
Astigmatism – people who have astigmatism will have an irregularly shaped cornea (egg-like or football-shaped, most often). Unlike myopia or hyperopia, when light enters through a cornea with astigmatism, the light is distorted and refracted to multiple different focal points within the eye. This can cause vision problems, both near and far, for individuals with astigmatism. There are two types of astigmatism; regular and irregular.
Regular – the eyeball is not spherical but is symmetrical; most common
Irregular – the eyeball is neither spherical nor symmetrical; rare
When it comes to solving refractive errors like astigmatism, there are a few options. The goal is to have the light that enters the eye focus properly on the retina in order to allow clear vision. Glasses and contact lenses counteract the irregular shapes of an individual’s corneas without any permanent alterations. Laser eye surgery physically corrects the shape of the cornea by removing tissue to allow the light to focus properly.
All of these options work for all three of the refractive errors (the less severe the distortion, the better success) but in today’s society, many individuals try to seek natural ways of fixing health problems.
You may have to ask your eye doctor how to cure astigmatism naturally because glasses and/or contacts might not be ideal options for everyone, and the surgery is usually the last resort. While finding Astigmatism cure naturally sounds almost impossible, there are several things you can do to help prevent it from getting worse. Regular eye doctor visits to catch and correct vision problems early on can help prevent related symptoms such as headaches. Also, healthy diet and exercise can help maintain proper blood flow, nutrients, and repairs to your eye tissues and keep your eyes working properly. However, if you are looking for a long-term solution for your astigmatism, laser surgery may be the right fit for you.
