In patients, whether young or old, sometimes poor vision can be the result of a number of factors such as changes in the body or abnormalities in the eye or visual system, eye diseases, side effects of medicine or injury. Many people also experience visual disturbances resulting from aging or eye stress. Aging and stress can cause changes in your vision, which may make it painful or difficult to get through everyday activities such as reading fine print or looking at a computer screen for extended periods of time. These vision problems can be expressed through the following symptoms: eye strain, headache, blurred vision, squinting and struggling with short or long distances.
Blurred vision is one of the most common signs of a vision problem. If you suffer from blurred vision when you're looking at distant objects or signs, you could very well have myopia, or be nearsighted. Blurred vision that's present when you are looking at something close by could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism because of an abnormality in the way the cornea is formed. No matter the reason you have blurry vision, it's essential that an optometrist thoroughly check your vision and decide on the best way to improve your sight.
Another common indicator of a vision problem is difficulty discerning shades or strength of color. This generally means the patient has color blindness. Color blindness is often not known to the patient until proven with a test. Color blindness is generally found in males. If present in a female it might mean she has ocular disease, and an optometrist should be consulted. For people who have difficulty distinguishing objects in minimal light, it is a sign of possible night blindness.
A condition commonly found in aging people is cataracts, which can have numerous telltale signs including: hazy sight that worsens in bright light, weak night vision, difficulty seeing small writing or details, muted or faded colors, improvement in near vision while distance vision worsens, painful inflammation around the eye, and an opaque white appearance to the normally dark pupil.
Throbbing eye pain, headaches, unclear vision, inflammation in the eye, rainbow coronas around lights, nausea and vomiting are indicators of glaucoma, a serious medical condition, which calls for immediate medical attention.
When it comes to children, it's useful to look out for weak eye movement, or eyes that cross in or out, which could indicate a condition known as strabismus. Certain things children might do, such as rubbing eyes, squinting, head tilting, or the need to close one eye in order to look at things better, often indicate this issue.
While clearly some conditions could be more problematic than others, anything that restricts clear eyesight will be a burden, and impact your quality of life. A short consultation with your optometrist can save you from being avoidably uncomfortable, or even more severe eye damage.
