Ongoing blurry vision is one of the most common complaints of people who are having trouble with their eyes. If it seems mild, it may seem like there is no need to go to the eye doctor to have it checked out. However, it's important to note that blurriness is not always caused by a simple refractive error. It is also an early warning sign of some serious eye diseases. These diseases can lead to functional or literal blindness, so you should always get your eyes checked right away if you're having trouble focusing them.
With a simple refractive error, the eye's lens focuses light in front of or behind the retina instead of directly onto it. This causes either nearsightedness or farsightedness depending on just where the focal point ends up. Typically, all it takes to get a clear view is a pair of prescription eyeglasses or contact lenses.
One of the reasons people don't take blurry vision as a sign of a serious problem is that most of the time, it turns out to be a refractive error. The problem with this line of thinking is that it isn't always caused by such a benign condition. Drs. Kopolow and Girisgen note that, among other things, it can be caused by conditions like:
Glaucoma is the result of too much pressure inside the eye. It can have many symptoms if allowed to progress. Some of these are blurry vision, tunnel vision, and halos around light sources like bulbs or the sun. Often, the "tunnel vision" effect involves blurriness at the outsides of your field of vision and clarity in the center, rather than outright blindness at the edges.
Technically, vision through cataracts is "cloudy," but many people describe it as blurry instead. Cataracts can become so clouded over that they cause blindness, but at first, strong glasses may be able to counter their effects. Replacement of the clouded lens with an artificial one fixes the problem.
Strokes and other major cardiovascular events can cause sudden blurry or double vision. If you experience double vision without the use of drugs or alcohol, you should get to a doctor right away to make sure you haven't suffered such an event.
These are just some of the problems that can include blurry vision as a symptom. Give yourself peace of mind, and make sure you are properly treated for any diseases by having your eyes examined by optometrists in Las Vegas.
Get your eyes checked on a regular basis for conditions like these that can often be spotted and treated before they even have the chance to cause symptoms.
