Poor vision in adults or children can be due to a number of factors such as changes in the body or irregularities in the eye, diseases affecting the eye, side effects of medication or injury. Lots of people also suffer from visual disturbances resulting from aging or eye stress. Aging and stress can result in changes in your eyesight, which might make it uncomfortable or difficult to get through normal activities, like reading books or working on a computer for extended periods of time. These vision problems can be expressed via the following symptoms: blurry vision, headaches, eye strain, squinting and struggling with short or long distances.
One of the most common signs of a vision problem can be blurred vision. If you have blurred vision when focusing on faraway objects, you may have myopia, or be nearsighted. If you have blurred vision when you're viewing something nearby this could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism due to a flaw in the shape of the cornea, or the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's really important that an eye doctor examine your eyes and prescribe a solution to help clarify your sight.
Another sign of a vision problem is trouble distinguishing shades or strength of color. This indicates a problem perceiving color, or color blindness. Interestingly, this condition is usually not known to the patient until diagnosed by testing. Color blindness is mostly something that affects males. If present in a female it could indicate ocular disease, and an optometrist needs to be consulted. If you struggle to distinguish between objects in minimal light, it is a sign of possible night blindness.
Cataracts, a condition commonly found in aging people can have numerous telltale signs which include: hazy sight that is worse in bright light, weak night vision, difficulty discerning small writing or objects, colors that appear faded or yellowed, improvement in near vision but a decline in distance vision, puffiness around the eye, and a milky white appearance to the usually dark pupil.
Throbbing pain in the eye, headaches, blurred vision, redness in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, a serious medical illness, which requires medical attention.
When it comes to children, it's useful to watch for uncoordinated eye movement, or crossed eyes, which could indicate a condition called strabismus. Specific behavior, such as rubbing one or both eyes, squinting, head tilting, or the need to shut one eye in order to see things better, can often point to this issue.
Though some conditions may be more serious than others, any disruption to clear eyesight can be a burden, and impact your quality of life. A brief consultation with your optometrist can save you from being avoidably uncomfortable, not to mention further eye and vision damage.
