Watching Out for Poor Vision

Poor vision in adults or children can be the result of a number of conditions including anatomical changes in the eye, eye diseases, side effects caused by medication or eye injuries. Many people also suffer from visual abnormalities resulting from aging or eye strain. These experiences can cause changes in your vision, which might sometimes cause pain and even make it harder to get through everyday activities, like reading books or using a computer for extended periods of time. Common signs and symptoms of such vision problems include blurry vision, headaches, eye strain, and struggling with close and far distances.

Blurred vision is one of the most oft-reported signs of a vision problem. If you report blurred vision when looking at faraway objects, you might be nearsighted, or myopic. Blurred vision that's present when you are looking at anything at close range could mean you suffer from farsightedness, or hyperopia. It can also be a sign of astigmatism because of an irregularity in the way the cornea is formed. In all cases of blurry vision, it is vital to have your eye doctor examine your vision and prescribe a solution to help clarify your sight.

Rapid flashes of light, often combined with floating black spots and the sensation of a dark curtain inhabiting a section of your vision indicates the chance of what's known as a retinal detachment. If this is the case, see your eye doctor as soon as you can, as this can have severe consequences for your vision

Another common sign of a vision problem is difficulty discerning shades or brightness of color. This is an indication of color blindness. Color vision defects are usually unknown to the patient until proven by testing. Color blindness is generally found in males. If a woman has problems seeing color it might represent ocular disease, and an eye care professional should be consulted. For people who have difficulty distinguishing objects in low light, it could mean the patient suffers from night blindness.

Cataracts, a condition frequently seen older patients can have a number of warning signs including: blurry vision that worsens in bright light, weak night vision, trouble seeing small writing or objects, the need for brighter light when reading, seeing duplicates in one eye, inflammation of the eye, and a milky white look to the usually dark pupil.

Throbbing eye pain, headaches, blurred sight, redness in the eye, colorful halos around lights, nausea and vomiting are also signs of glaucoma, a serious medical condition, which needs medical attention.

With younger patients, it's useful to watch for weak eye movement, or eyes that cross in or out, which may indicate a vision problem called strabismus. Certain behavior, like rubbing one or both eyes, squinting, head tilting, or needing to shut one eye in order to see things better, often indicate strabismus.

Even though some conditions could be more serious than others, any disruption to good eyesight will be something that really affects your quality of life. A quick visit to your optometrist can save you from unnecessary discomfort, not to mention even more severe eye problems.
