Myopia: treating nearsightedness
June 19, 2014
You have probably heard of myopia or you may even be affected by this very common visual affliction. Myopia, or nearsightedness, is a medical condition which causes short range vision to be clear, but long distance vision to be blurred. Myopia can occur if an individual’s eyeball is overly elongated or if the curvature of the cornea is too extreme. This can cause the light being captured by the eye to not be properly focused, distorting objects in the distance and making them appear blurred.
The most immediate sign of myopia is a difficulty with viewing objects in the distance. If your child complains about not being able to see the chalkboard at school properly, there is a chance that they could be suffering from myopia and their nearsightedness is preventing them from being able to fully participate in class. Other common complaints include difficulty watching television or movies and even difficulty using the computer at certain distances. Although individuals with nearsightedness typically have clear near vision, some cases of high myopia also affect an individual’s ability to view objects at close range. In these cases, only objects seen at an extremely close range can be viewed clearly and myopia can affect activities such as smartphone use and reading.
Although the exact cause of myopia is not known, it appears to be influenced by hereditary factors and visual stress. If one or both of your parents suffer from myopia, it is more likely that you will also develop nearsightedness. Stress from intense periods of reading or computer use can also lead to nearsightedness. The eye strain caused by these activities and other close range visual work appears to play a role in enabling the development of myopia. Overusing close range vision can also cause temporary myopia as it makes it more difficult for your eyes to refocus on objects in the distance. Over time, this may lead to permanent myopia.
Despite the absence of a conclusive theory, the increased occurrence of myopia in recent times has been linked to the prevalence of near work in modern society. A large portion of modern life involves the use of close range vision to read books or perform tasks on computer/phone screens both of which can build strain on eyes and heighten the possibility of myopia. There is also an argument which claims that myopia is more common in the modern world due to the less visually stimulating environments of industrialized societies. Due to a large portion of the population spending their time indoors, many individuals have less opportunities to use their eyes as dynamically as they would in outdoor landscapes which could possibly result in irregular growth of the eye.
Although myopia can be mediated through the use of corrective lenses and contacts, the only way to fully treat nearsightedness is through LASIK. Laser eye surgery methods such as LASIK are safe and easy ways for most patients to improve their vision and experience great eyesight.
