Poor vision in adults or children can be caused by a number of conditions including changes in the body or in the eye or visual system, eye diseases, side effects caused by medication or injury. Many people also experience visual abnormalities resulting from aging or eye strain. This can lead to changes in your eyesight, which can make it painful or difficult to get through everyday activities, like reading the newspaper or working on a computer for extended periods of time. Common signs and symptoms of these types of vision problems include blurry vision, headaches, eye strain, and trouble seeing from 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 or signs, you could very well be myopic or nearsighted. Blurred vision that's present when you are looking at something at close range could mean you suffer from farsightedness, or hyperopia. It can also mean you have astigmatism which occurs due to an abnormality in the way the cornea is formed. No matter the reason you have blurry vision, it is essential to have your optometrist 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 strength of color. This indicates a problem perceiving color, or color blindness. Color vision defects are often not known to the patient until diagnosed via a consultation. Color blindness is mainly something that affects males. If a woman has difficulty perceiving color it might represent ocular disease, in which case, an eye care professional needs to be consulted. For those who have difficulty distinguishing objects in minimal light, it is a sign of possible night blindness.
Cataracts, a condition frequently seen elderly people have a number of indicating signs including: hazy vision that worsens in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or objects, colors that appear faded or yellowed, improvement in near vision while distance vision worsens, painful inflammation around the eye, and a milky white appearance to the normally dark pupil.
Pulsing eye pain, headaches, blurry vision, inflammation in the eye, colorful halos around lights, nausea and vomiting are also signs of glaucoma, a serious medical illness, which needs medical attention.
With younger patients, we recommend you watch for weak eye movement, or eyes that cross in or out, which may indicate a condition known as strabismus. Some things children might do, such as rubbing one or both eyes, squinting, head tilting, or the need to close one eye to see things better, often point to strabismus.
If you are familiar with any of the symptoms mentioned here, see your eye doctor as soon as possible. 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 short visit to your optometrist can prevent unnecessary discomfort, or even more severe eye and vision problems.
