Poor Vision: Know The Signs

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 of medicine or injuries to the eye. Commonly, people also suffer from visual disturbances associated with age or eye stress. These experiences can result in changes in your eyesight, which might sometimes make it painful or difficult to get through normal activities, like reading the newspaper or working on a computer for long periods. Common symptoms of such vision problems include blurry vision, headaches, eye strain, and problems seeing at close and far distances.

Blurred vision is one of the most common signs of a vision problem. If you report blurred vision when looking at distant objects or signs, you may very well be nearsighted, or myopic. If you have blurred vision when you're looking at something nearby it could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism due to a flaw in the way the cornea is formed. In all cases of blurry vision, it's vital to have your eye doctor examine your eyes and decide on the most effective way to improve your sight.

Another indicator of a vision problem is the inability to distinguish between different colors or brightness of color. This is an indication of a color perception problem, or color blindness. Color blindness is usually unknown to the patient until proven via a consultation. Color blindness is generally found in males. If a woman has difficulty perceiving color it could indicate ocular disease, in which case, an optometrist needs to be consulted. For people who struggle to distinguish between objects in minimal light, it is a sign of possible night blindness.

A condition commonly found in older people is cataracts, which have a number of indicating signs which include: unclear vision that is worse in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or objects, the need for brighter light when reading, seeing duplicates in one eye, redness around the eye, and an opaque white look to the usually dark pupil.

Pulsing pain in the eye, headaches, blurry vision, inflammation in the eye, rainbow halos around lights, nausea and vomiting are also signs of glaucoma, a serious medical condition, which requires immediate medical attention.

In children, it's useful to look out for weak eye movement, or eyes that cross in or out, which could indicate a condition called strabismus. Specific behavior, such as rubbing one or both eyes, squinting, or the need to shut one eye to see things better, can often indicate strabismus.

While clearly some conditions may be more problematic than others, anything that limits normal vision can be something that really affects your quality of life. A short visit to your optometrist can save you from being avoidably uncomfortable, or even more severe eye and vision damage.
