Have you recently noticed that objects that are too close to you look overly blurry? Maybe this problem started off as minor one and has become worse over time, or maybe it came on suddenly. In either case, it is important to see your eye doctor and figure out the cause. Here's a look at three conditions that may be at fault.

Hyperopia

Also known as farsightedness, this problem occurs when the eye is shaped in such a way that the light entering through the eye focuses behind the retina (the light detecting membrane at the back of the eye) rather than directly on the retina. This causes things to look a little "out of focus," and the closer to the person an object is, the more "out of focus" it will appear.

Hyperopia commonly develops as patients age. It is generally nothing to be concerned about. If this is found to be the cause of your blurry vision, your eye doctor will likely recommend that you wear glasses some or all of the time to correct for it. The hyperopia may become worse as you continue to age and your eyes continue to change shape, but rarely is it not manageable with glasses.

Diabetic Retinopathy

 If you are a diabetic, then there's a chance that something more sinister is to blame for your blurry vision. Diabetic retinopathy is a condition in which prolonged high blood sugar levels cause damage to the retina and associated blood vessels. Doing a better job of controlling your blood sugar in the future can help prevent the retinopathy from becoming worse. If your condition is in the more advanced stages, a specialized laser surgery can be used to slow its progression. However, you will never regain your vision completely.

Screen Fatigue

If you spend a lot of time each day staring at a computer screen or another type of screen, this may at least partly explain your condition. The high intensity light emerging from most screens, combined with the precise focus your eyes must maintain when you're looking at one, can lead to fatigue which causes your vision to look blurry. Your eye doctor will likely recommend taking breaks from staring at the screen, along with tips like turning down the brightness of your screen and minimizing night time screen use in order to manage the condition. Using moisturizing eye drops may also help fight screen fatigue, since it is often made worse by eye dryness. Contact an ophthalmologist, like http://arizonaeyes.net, for more information.
