If you have been having vision problems for more than a month, it is best to visit your doctor and have him or her take a look at your eyes. He or she can check the following factors: Your eye pressure, your color vision (if you have any), any light disturbances around you, and your peripheral vision (how well you can see small details when you are facing away from them). Vision problems are sometimes referred to as refractive errors. For example, if you have the common problem of lazy eye, which is when light rays focus on the retina instead of on the objects you are looking at, this is a refractive error. Other refractive errors include hyperopia, myopia, and astigmatism.
Computer use also contributes to vision problems because computer monitors and computer screens magnify errors that happen near visual centers, such as the eye’s pupils. When you are using a computer for long periods at the same time, the eyeballs naturally relax and do not work as they should. If you often experience vision problems after using a computer, you should take breaks every few minutes to check your eyes.
There are also two types of refractive errors: primary and secondary. Primary refractive errors occur when you are focusing on one point in the scene and your eyes focus light rays automatically. Secondary refractive errors occur when your eyes focus light rays, even if you are not trying to focus on anything specific.
Vision Loss Because of a vision problem called cranial nerve palsy, some people suddenly lose their ability to move their eyes. This can happen because of an injury or illness that causes a problem with the muscles that control eye movement. As a result, the eye movements are not as coordinated, and you have difficulty seeing clearly. The most common symptom associated with this type of vision problem is that the patient experiences blurry vision when looking at nearby objects. In more severe cases, patients may experience nausea, blurred vision, and headaches as a result of cranial nerve palsy.
Vision Disturbance If you suddenly develop any of these symptoms, you may have a vision problem called blurred vision, double vision, or discomfort in the eyes. This problem occurs when light from the environment (when it is reflected off a cloudy window) appears blurred. This can be accompanied by a variety of other symptoms, including tingling, redness, or even pain. Blurry vision and discomfort in the eyes often result from high levels of glucose in the blood, such as after eating a sugary snack, or from a traumatic experience.
A comprehensive eye examination will help you determine if you have one of these vision problems, and it will also alert you to other potential issues. A glaucoma specialist can test your eyes for the presence of glaucoma. He can also examine your eyes for any signs of nerve damage from damage to your capillaries. He can then determine if you have any kind of refractive error. If you do have one or more of these vision problems, an eye examination is really the first step. The vision specialist can then decide on the best course of treatment.
