Watching Out for Poor Vision

Poor vision in adults or children can be the result of a few conditions including changes in the body or in the eye, eye diseases, side effects due to medicine or injuries to the eye. Lots of people also report visual disturbances resulting from aging or eye stress. Aging and stress can result in changes in your vision, which might cause discomfort and even make it harder to perform everyday activities, like reading books or looking at a computer screen for extended periods of time. Common signs and symptoms of such vision problems include eye strain, headache, blurred vision, and problems seeing at short or long distances.

Blurred vision is one of the most common signs of a vision problem. If you have blurred vision when you're looking at distant objects or signs, you could very well be nearsighted, or myopic. If you suffer from blurred vision when you're looking at anything nearby it may be a sign of hyperopia, or farsightedness. It can also be a symptom of astigmatism which occurs because of a flaw in the way the cornea is formed, or sometimes the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's vital to have your eye care professional thoroughly check your eyes and prescribe a solution to help clarify your sight.

Another common warning sign of a vision problem is the inability to distinguish between different colors or brightness of color. This indicates color blindness. Interestingly, this condition is generally not known to the patient until diagnosed by testing. Color blindness is mainly found in males. If a woman has difficulty seeing color it could represent ocular disease, and an eye doctor needs to be consulted. For those who struggle to distinguish between objects in dim light, it could mean the patient suffers from night blindness.

An issue frequently seen in older patients is cataracts, which have a number of telltale signs which include: hazy sight that worsens in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or details, colors that appear faded or yellowed, unexpected improvement in near vision but a decline in distance vision, painful inflammation of the eye, and an opaque white look to the usually dark pupil.

Pulsing pain in the eye, headaches, blurred vision, redness in the eye, rainbow coronas around lights, nausea and vomiting are also signs of glaucoma, an acute medical condition, which calls for medical attention.

In children, it's useful to look out for uncoordinated eye movement, or eyes that cross in or out, which could indicate a vision problem known as strabismus. Certain behavior in children, like rubbing one or both eyes, squinting, or the need to close one eye to look at things better, can often point to strabismus.

Though some conditions may be more problematic than others, anything that limits normal sight can be something that compromises your quality of life. A short consultation with your optometrist can save you from unnecessary discomfort, or further eye and vision damage.
