Often, when either children an adults experience poor vision, it can be caused by a number of factors including changes in the body or abnormalities in the eye, diseases affecting the eye, side effects due to medication or injury. Lots of people also suffer from visual disturbances resulting from aging or eye strain. These experiences can lead to changes in your vision, which may make it uncomfortable or difficult to perform normal activities, like reading books or working on a computer for extended periods of time. Common symptoms of such vision problems include blurry vision, headaches, eye strain, squinting and trouble seeing from short or long distances.
Blurred vision is one of the most commonly occurring signs of a vision problem. If you suffer from blurred vision when you're looking at distant objects, you could be myopic or nearsighted. Blurred vision that's present when you are looking at objects close by could mean you suffer from farsightedness, or hyperopia. Blurred vision can also be a symptom of astigmatism due to a flaw in the shape of the cornea, or sometimes the curvature of the lens inside the eye. Whatever the cause of blurry vision, it is vital to have your eye care professional examine your eyes and decide on the best way to improve your sight.
A sudden onset of flashes of light, together with floating black spots and the feeling of a dark curtain or veil blocking a portion of your vision indicates you might have a retinal detachment. If this is the case, see your eye doctor promptly, as this can have serious consequences.
Another common indicator of a vision problem is difficulty discerning different colors or intensity of color. This generally means the patient has a color perception problem, or color blindness. Color blindness is generally not known to the patient until discovered with a test. Color blindness is generally found in males. If present in a female it may represent ocular disease, and an eye care professional needs to be consulted. For those who have difficulty distinguishing objects in dim light, it could mean the patient suffers from night blindness.
A problem commonly found in elderly people is cataracts, which have numerous warning signs including: blurry sight that weakens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or objects, the need for brighter light when reading, seeing duplicates in one eye, inflammation of the eye, and a milky white look to the normally dark pupil.
Pulsing pain in the eye, headaches, blurred sight, redness in the eye, colorful halos around lights, nausea and vomiting are indicators of glaucoma, a severe medical condition, which needs medical attention.
When it comes to children, we recommend you watch for weak eye movement, or eyes that cross in or out, which may indicate a condition known as strabismus. Specific behavior in children, like rubbing one or both eyes, squinting, head tilting, or needing to close one eye in order to see things better, can often indicate this issue.
If you experience any of the symptoms listed here, make an appointment with your eye doctor as soon as possible. Though some conditions may be more problematic than others, anything that restricts good eyesight can be a burden, and impact your quality of life. A quick consultation with your optometrist can prevent being avoidably uncomfortable, or further eye problems.
