A decline in strong vision is usually caused by a number of factors including changes in the body or abnormalities in the eye or visual system, diseases affecting the eye, side effects due to medication or eye injuries. Commonly, people also report visual abnormalities associated with age or eye strain. These experiences can cause changes in your vision, which might make it uncomfortable or difficult to perform normal activities, like reading the newspaper or looking at a computer screen for extended periods of time. Common signs and symptoms of these types of vision problems include blurry vision, headaches, eye strain, squinting and struggling with short or long distances.
One of the first signs of a vision problem can be blurred vision. If you suffer from blurred vision when you are looking at faraway objects or signs, you might very well be myopic or nearsighted. Blurred vision that's present when you are looking at anything at close range could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a sign of astigmatism because of an irregularity in the shape of the cornea. Whatever the cause of blurry vision, it's vital that an optometrist examine your eyes and prescribe a solution to help clarify your sight.
Another common warning sign of a vision problem is difficulty discerning shades or intensity of color. This indicates a problem perceiving color, or color blindness. Interestingly, this condition is often unknown to the patient until diagnosed by testing. Color blindness is mainly found in males. If a woman has difficulty perceiving color it might mean she has ocular disease, in which case, an eye doctor should be consulted. If you can't see objects in minimal light, it is a sign of possible night blindness.
Cataracts, a condition frequently seen aging patients can have a number of indicating signs which include: blurry vision that worsens in bright light, trouble seeing in the dark or reduced light, trouble discerning small writing or objects, the need for brighter light when reading, double or triple vision in one eye only painful redness around the eye, and a milky white appearance to the normally dark pupil.
Pulsing eye pain, headaches, blurred sight, inflammation in the eye, colorful halos around lights, nausea and vomiting are also signs of glaucoma, a severe medical condition, which needs prompt medical attention.
When it comes to children, it is important to keep an eye out for uncoordinated eye movement, or eyes that cross in or out, which may indicate a condition called strabismus. Some behavior, like rubbing eyes, squinting, or the need to close one eye in order to look at things better, can often point to this issue.
If you are familiar with any of the symptoms listed here, see your eye doctor promptly. Though some conditions are more problematic than others, anything that restricts normal sight will be a burden, and impact your quality of life. A short visit to your optometrist can prevent unnecessary discomfort, or even more severe eye damage.
