Poor Vision: Know The Signs

In patients, whether young or old, sometimes poor vision can be caused by several possible factors such as anatomical changes or irregularities in the eye or visual system, eye diseases, side effects due to medicine or eye injuries. Lots of people also suffer from visual abnormalities associated with age or eye strain. Aging and stress can result in changes in your vision, which can sometimes make it uncomfortable or difficult to perform everyday activities, like reading fine print or looking at a computer screen for extended periods of time. Common signs and symptoms of these types of vision problems include eye strain, headache, blurred vision, squinting and struggling with close and far distances.

One of the first signs of a vision problem can be blurred vision. If you report blurred vision when you are looking at faraway objects or signs, you could be nearsighted, or myopic. Blurred vision that's present when you are looking at objects nearby could mean you suffer from farsightedness, or hyperopia. Blurred vision can also be a sign of astigmatism because of a flaw in the way the cornea is formed. No matter the reason you have blurry vision, it is really important to have your eye care professional examine your vision 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 generally means the patient has color blindness. Interestingly, this condition is usually unknown to the patient until proven with a test. Color blindness is generally found in males. If a woman has problems seeing color it may indicate ocular disease, in which case, an optometrist should be consulted. If you have difficulty distinguishing objects in dim light, it is a sign of possible night blindness.

An issue frequently seen in elderly people is cataracts, which can have several indicating signs which include: hazy vision that is worse in bright light, weak night vision, trouble discerning small writing or objects, muted or faded colors, unexpected improvement in near vision but a decline in distance vision, redness around the eye, and a milky white appearance to the normally dark pupil.

Pulsing eye pain, headaches, blurry vision, inflammation in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, an acute medical illness, which requires immediate medical attention.

In children, it is important to watch for uncoordinated eye movement, or crossed eyes, which may indicate a vision problem called strabismus. Some behavior, such as rubbing one or both eyes, squinting, head tilting, or needing to shut one eye to focus better, often point to this issue.

If you are familiar with any of the symptoms we've mentioned here, see your eye doctor promptly. Even though some conditions may be more serious than others, anything that restricts clear sight will be a burden, and impact your quality of life. A short appointment with your optometrist can prevent being avoidably uncomfortable, or even more severe eye and vision problems.
