Probably the most common kind of vision problem that people have these days is myopia, commonly known as nearsightedness. For nearsighted people, they can only see things clearly when they are up close, but when the object is at a distance, they will need glasses to see them clearly. The lens in the eyes of people with myopia are generally too thin so that the image is primarily focused right in front of the retina. In this article, you will learn about the things that are the causes of nearsightedness, and also some things that you can do to prevent this from happening.
There are actually many causes of nearsightedness, and there is no particular age wherein the condition is most common; there are actually instances when a person is born already myopic, and there are times when people get when they go over twenty years old and start using their eyes for their work. One sign that tells that a person is nearsighted is when he squints when trying to see far off objects, another symptom is frequent migraine attacks.
Nearsightedness can actually be corrected by wearing eyeglasses or contact lenses, or if you can afford it, you can get surgery to reshape the cornea of your eyes so that the images are focused properly. But besides these artificial methods of improving eyesight, there are also a couple of natural ways that you can try. For instance, you can do some adjustments in your diet to include more foods that are full of vitamin A, like carrots, spinach, and broccoli. You should also give your eyes a rest from time to time, especially if your work requires you to stare at a computer monitor for hours on end. It is also recommended that you do eye exercises to make your eyes stronger and able to see things that you normally could not.
One exercise you can try requires you to just tightly close your eyes for ten seconds and then opening them again widely for another ten seconds, easy is it not?
Another way to prevent the onset of myopia is to get rid of stress. One of the causes of nearsightedness is when the muscles surrounding the eyes become so tense that they actually put too much pressure on the eyeballs; and the most common thing that causes the muscles to tense up too much is mental stress. So, to somehow prevent getting myopia at a young age, you should try to relax every once in a while. If your work gets too toxic for you to handle, you should go to a day spa during the weekend so that you can relax and unwind without having to think about your work.
You should always keep in mind the tips mentioned above if you do not want to get stuck wearing a pair of thick glasses or contact lenses that often irritate the eyes. Knowing what nearsightedness means and how you can prevent it from happening to you will greatly improve your chances of going through life with nearly-perfect vision.
