A decline in strong vision is usually the result of several possible conditions such as anatomical changes in the eye, eye diseases, side effects caused by medication or injuries to the eye. Lots of people also suffer from visual disturbances resulting from aging or eye strain. This can cause changes in your vision, which can make it uncomfortable or difficult to perform daily activities such as 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 trouble seeing from short or long distances.
One of the first signs of a vision problem can be blurred vision. If you report blurred vision when you're focusing on faraway objects, you may be myopic or nearsighted. Blurred vision that's present when you are looking at anything at close range may be a sign of farsightedness, or hyperopia. Blurred vision can also be a symptom of astigmatism which occurs due to an irregularity in the way the cornea is formed, or sometimes the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's essential to have your eye care professional examine your vision and decide on the most effective way to rectify your sight.
Another common indicator of a vision problem is difficulty discerning shades or strength of color. This is an indication of a problem perceiving color, or color blindness. Interestingly, this condition is generally unknown to the patient until proven by testing. Color blindness is mostly found in males. If present in a female it might indicate ocular disease, and an eye care professional needs to be consulted. If you have difficulty distinguishing objects in minimal light, it is a sign of possible night blindness.
Cataracts, a condition frequently seen elderly patients have numerous telltale signs including: blurry vision that weakens in bright light, trouble seeing in the dark or reduced light, trouble discerning small writing or objects, colors that appear faded or yellowed, unexpected improvement in near vision while distance vision worsens, painful puffiness of the eye, and an opaque white appearance to the normally dark pupil.
Pulsing eye pain, headaches, blurry sight, inflammation in the eye, colorful coronas around lights, nausea and vomiting are also signs of glaucoma, a severe medical illness, which needs prompt medical attention.
When it comes to children, it's useful to watch for uncoordinated eye movement, or crossed eyes, which may indicate a vision problem called strabismus. Specific things children might do, such as rubbing one or both eyes frequently, squinting, or the need to shut one eye in order to look at things better, can often indicate this issue.
If you are familiar with any of the symptoms mentioned here, make an appointment with your eye doctor promptly. Though some conditions may be more serious than others, anything that restricts normal eyesight will be something that compromises your quality of life. A short consultation with your optometrist can save you from unnecessary discomfort, or even more severe eye and vision damage.
