Poor vision in adults or children can be the result of several possible factors including anatomical changes or irregularities in the eye or visual system, eye diseases, side effects due to medication or eye injuries. Lots of people also suffer from visual abnormalities due to aging or eye strain. This can cause changes in your eyesight, which might make it painful or difficult to get through normal activities, like reading books or working on a computer for long periods. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, and struggling with close and far distances.
Blurred vision is one of the most commonly occurring signs of a vision problem. If you suffer from blurred vision when looking at distant objects or signs, you could very well be myopic or nearsighted. If you suffer from blurred vision when you're viewing objects nearby this may be a sign of farsightedness, or hyperopia. It 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 vision and decide on the best way to rectify your sight.
Another common warning sign of a vision problem is difficulty discerning different colors or intensity of color. This generally means the patient has a problem perceiving color, or color blindness. Color blindness is usually unknown to the patient until discovered with a test. Color blindness is generally found in males. If present in a female it might represent ocular disease, and an eye care professional needs to be consulted. For people who can't see objects in low light, it is a sign of possible night blindness.
An issue commonly found in elderly people is cataracts, which can have a number of indicating signs including: hazy sight that worsens in bright light, trouble seeing in the dark or reduced light, trouble discerning small writing or objects, muted or faded colors, improvement in near vision but a decline in distance vision, painful puffiness around the eye, and a milky white look to the normally dark pupil.
Throbbing pain in the eye, headaches, unclear sight, redness in the eye, colorful halos around lights, nausea and vomiting are also signs of glaucoma, a severe medical condition, which requires prompt medical attention.
With younger patients, it is important to watch for weak eye movement, or eyes that cross in or out, which could indicate a vision problem called strabismus. Certain behavior in children, like rubbing one or both eyes frequently, squinting, or needing to close one eye to look at things better, often indicate strabismus.
While clearly some conditions could be more problematic than others, anything that restricts clear sight can be something that compromises your quality of life. A short appointment with your optometrist can save you from unnecessary discomfort, not to mention further eye damage.
