Astigmatism is a common visual impairment that affects about one of every three people. The eye’s cornea should be round but those with astigmatism have oval corneas. This kind of shape results in refraction that creates blurred vision. Fortunately, this condition isn’t dangerous and can easily be corrected with prescription eyewear. You will need to talk to your doctor to get a proper diagnosis. An eye exam will be conducted to check visual Acuvue Oasys Astigmatism. The curvature of the corneas will also be measured with a special tool. From these, the doctor can determine the exact level of correction for each.
Symptoms of Astigmatism
Individuals with astigmatism experience symptoms such as blurred vision, eyestrain, and headaches. They often need to squint in order to see more clearly. They might have difficulty seeing in the dark. If these match your experience, then you should see a doctor as soon as possible for an eye exam. This is a condition that can develop in both children and adults. Some cases are mild enough that there are no obvious symptoms that would alert the person about the problem. Often, it is found only after an eye exam for a different purpose.
Types of Refractive Errors
In hyperopic astigmatism, a person will experience farsightedness in one or two of the principal meridians. In myopic astigmatism, it will be the reverse with the person having nearsightedness. There are also cases of mixed astigmatism in which both farsightedness and nearsightedness exists. Doctors will look closely to see if the situation is mild enough that it can be corrected with eyewear. Another treatment option is to get a refractive surgery for a lasting improvement in vision. Many are not keen on taking the risk so they simply wear glasses instead as a non-invasive solution.
Using Contact Lenses for Correction
The program with eyeglasses is that they are bulky and cumbersome to use. There are more fashionable frames right now but many still feel like these don’t look good on them. Contact lenses may be a better solution if they want something small, light, and discreet. They sit directly on the eye and move naturally with it. They alter the direction of the light rays to prevent refraction and achieve better focus for a better vision.
One example of this is the Acuvue Oasys Astigmatism Contact Lenses. These come in 1-day and 2-week options. These are great for playing sports or just enjoying a movie.
