Watching Out for Poor Vision

A decline in strong vision is usually caused by a number of factors including anatomical changes or abnormalities in the eye or visual system, diseases affecting the eye, side effects due to medicine or injury. Lots of people also suffer from visual disturbances due to aging or eye strain. These experiences can lead to changes in your vision, which can cause discomfort and even make it harder to get through everyday activities such as reading books or looking at a computer screen for long periods. Common symptoms of such vision problems include blurry vision, headaches, eye strain, and trouble seeing from close and far distances.

One of the most common signs of a vision problem can be blurred vision. 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 sign of astigmatism which occurs because of an abnormality in the way the cornea is formed, or the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's vital to have your eye doctor thoroughly check your vision and prescribe a solution to help clarify your sight.

Another sign of a vision problem is trouble distinguishing different colors or strength of color. This is an indication of a color perception problem, or color blindness. Color vision defects are usually unknown to the patient until discovered by testing. Color blindness is mainly something that affects males. If present in a female it may represent ocular disease, and an optometrist needs to be consulted. For people who have difficulty distinguishing objects in minimal light, it is a sign of possible night blindness.

A problem frequently seen in aging people is cataracts, which can have several telltale signs including: blurry sight that is worse in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or objects, muted or faded colors, improvement in near vision but a decline in distance vision, inflammation of the eye, and a pale look to the normally dark pupil.

Throbbing pain in the eye, headaches, unclear vision, inflammation in the eye, rainbow rings around lights, nausea and vomiting are also signs of glaucoma, a severe medical condition, which calls for prompt medical attention.

When it comes to children, it is important to look out for weak eye movement, or crossed eyes, which may indicate a vision problem called strabismus. Certain things children might do, like rubbing one or both eyes frequently, squinting, or needing to shut one eye to see things better, can often point to strabismus.

While clearly some conditions may be more severe than others, anything that limits normal sight will be something that compromises your quality of life. A brief consultation with your optometrist can prevent being avoidably uncomfortable, not to mention even more severe eye and vision problems.
