eyeglasses can correct nearsightedness for many individuals
In fact, the National Institutes of Health (NIH) estimates that close to 10% of the American population suffers some form of nearsightedness. The majority of individuals who suffer from nearsightedness do so because of their nearsightedness or farsightedness. But, contact lenses may also be used for individuals who suffer from astigmatism. In this article, we’ll explain some of the effects of contact lenses on astigmatism and its correction via contacts.
One of the most common effects of nearsightedness and astigmatism is blurred vision. Most individuals with myopia report being able to see small shapes and flashes, but cannot see anything at all when looking at large or distant objects. However, some individuals with myopia can see both nearby and distant objects clearly, even if they are not facing either one of these directions. This is primarily due to the fact that the focusing power of the eyes decreases as the eyes near each other.
types suffer from astigmatism
Another effect of nearsightedness and farsightedness is refractive errors. This refractive error results in an image where the far away objects are distorted and appear closer while the near objects stand out more. A refractive error is caused by a reduction in the diameter of an individual’s eyeball, which creates an image wherein the faraway objects appear closer while the near objects stand out more.
Some types suffer from astigmatism, which is a condition where the front surface of the cornea is slightly irregular. Because of this condition, it is rare for people with myopia and farsightedness to be able to correctly focus on nearby objects. While this type of condition is most common in types, it can affect anyone. However, it can become more severe in people who wear contact lenses, don’t wear glasses or have a habit of shifting their gaze from one eye to the other.
start testing for your vision health
If you do not know whether you have myopia, farsightedness or some combination of the two, it is important to visit an eye care professional. Myopia or farsightedness may be corrected with contact lenses, glasses or refractive surgery. It is always better to start testing for your vision health early in life so you can prevent the serious consequences of blurry vision.
Be sure to discuss your nearsightedness or farsightedness with your family doctor or an eye care professional before taking any kind of prescription medications. The professional can help you decide if the prescriptions are right for you and if you would be better off wearing contact lenses, glasses or refractive surgery. If you are thinking of these options, be sure to ask your family doctor about the benefits and risks of the treatment methods.
