Poor vision in adults or children can be caused by several possible conditions including anatomical changes or irregularities in the eye, diseases affecting the eye, side effects of medication or injuries to the eye. Lots of people also experience visual disturbances resulting from aging or eye strain. These experiences can result in changes in your eyesight, which might make it painful or difficult to perform daily activities such as reading the newspaper or looking at a computer screen for extended periods of time. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, and trouble seeing from short or long distances.
Blurred vision is one of the most oft-reported signs of a vision problem. If you have blurred vision when looking at distant objects, you might be nearsighted, or myopic. If you suffer from blurred vision when you're looking at anything at close range it may be a sign of hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism which occurs because of an abnormality in the way the cornea is formed. Whatever the cause of blurry vision, it's vital that an eye care professional examine your eyes and decide on the most effective way to rectify your sight.
Another common indicator of a vision problem is trouble distinguishing different colors or brightness of color. This generally means the patient has color blindness. Color vision defects are often not known to the patient until discovered with a test. Color blindness is mostly something that affects males. If a woman has problems seeing color it may indicate ocular disease, in which case, an optometrist should be consulted. For people who have difficulty distinguishing objects in dim light, it is a sign of possible night blindness.
An issue frequently seen in elderly patients is cataracts, which can have several telltale signs which include: unclear sight that is worse in bright light, weak night vision, trouble seeing small writing or objects, muted or faded colors, double or triple vision in one eye only puffiness around the eye, and a milky white appearance to the usually dark pupil.
Throbbing pain in the eye, headaches, blurred sight, redness in the eye, colorful rings around lights, nausea and vomiting are indicators of glaucoma, an acute medical illness, which requires medical attention.
In children, it is important to look out for weak eye movement, or crossed eyes, which may indicate a condition called strabismus. Specific behavior in children, such as rubbing eyes, squinting, or the need to shut one eye in order to look at things better, often indicate strabismus.
Though some conditions are more serious than others, any disruption to clear eyesight will be something that compromises your quality of life. A quick consultation with your optometrist can prevent unnecessary discomfort, or further eye and vision damage.
