What Causes Blurry Eyes and How Can You Treat Them?
Blurry eyes and blurred vision can be a result of a number of things-some serious and some not so serious. However, in almost every case they can cause frustration and be an unwelcomed experience.
Sometimes, the cause of blurry eyes is simply due to the fact that your eye glasses need to be upped in their strength or you have residue on your contact lenses. Many people end up wearing their contacts past the date that they should have been changed and over the course of time, residue can build up on the contacts and make your vision appear blurry.
Other times, people continue wearing the same glasses for years and go without getting new eye exams. Sometimes, vision can worsen over time, or change, and simply getting a stronger prescription in eyeglasses is enough to correct the vision.
The weakening of the muscles which can cause your lens to misshapen is the most common cause of blurry vision. Loss of elasticity, which occurs naturally with aging, can also cause vision to blur.
Myopia and hyperopia, which are just terms for being near-sighted and far-sighted, can also be causes. You might notice that objects appear blurry at a distance, or that they appear blurry when they are close to you. In myopia, this usually happens when the cornea has too much curve to it. In hyperopia, it can happen when the eyes is too short. The good news is that in most cases, vision can be corrected with glasses or contacts when it comes to either one of these conditions.
If you notice that your vision is only blurred at night, it could be due to cataracts, especially if you are of advanced age. Cataracts can make bright lights at night, including headlights, difficult to look at, too, because they can be blinding.
One of the most serious causes of blurry vision is macular degeneration which is when the neurons in the eyes begin losing their light. Macular degeneration is a very serious disease and needs to be diagnosed and treated by a physician. It can’t be treated be eyeglasses or contacts alone.
A less serious cause of blurred vision is dry eyes. Your eyes need to produce tears in order to stay hydrated. However, sometimes eyes don’t produce enough tears or the tears that they do produce are not of very good quality. Along with blurred vision, you can also experience uncomfortable dryness and itching, too. Eye drops can be purchased from most drugstores. However, if the dryness does not go away, or if the eye drops do not help, you might need to visit your physician to get something stronger.
There are some diseases and conditions that can affect the eyes and make vision blurry, too, as a side effect. If you notice that your vision goes blurry when you get a headache, for instance, you might suffer from migraines. Blurry vision can also occur when your body is dehydrated. In addition, blurry vision can be a symptom of diabetes, as well. All of these should be checked out, especially if your blurred vision is accompanied by any other symptom.
It is very important not to take blurry eyes carelessly. Although for the most part blurred vision can be treated with new glasses or contacts, or even with eye drops, it can also be a symptom of something far more serious. For that reason, you should definitely visit your doctor to find out what the underlying problem might be. Most of the time, eye conditions can be treated. However, in order to be treated effectively, some conditions must be treated right away and should not be ignored.
