In patients, whether young or old, sometimes poor vision can be caused by a number of conditions such as anatomical changes or abnormalities in the eye, eye diseases, side effects of medicine or eye injuries. Lots of people also experience visual abnormalities due to aging or eye stress. This can cause changes in your vision, which can sometimes make it uncomfortable or difficult to perform normal activities such as reading books or working on a computer for long periods. These vision problems can be expressed via the following symptoms: blurry vision, headaches, eye strain, squinting and trouble seeing from close and far distances.
One of the first signs of a vision problem can be blurred vision. If you report blurred vision when you are focusing on faraway objects, you might very well be myopic or nearsighted. If you have blurred vision when you're viewing something at close range this may be a sign of hyperopia, or farsightedness. It can also be a symptom of astigmatism because of an abnormality in the shape of the cornea, or sometimes the curvature of the lens inside the eye. In all cases of blurry vision, it is essential that an optometrist examine your vision and prescribe a solution to help clarify your sight.
A sudden onset of flashes of light, often combined with floating black spots and the sensation of a dark curtain blocking a portion of your vision indicates the chance of what's known as a retinal detachment. In this case, visit your eye doctor right away, as it can have severe consequences.
Another warning sign of a vision problem is the inability to distinguish between shades or intensity of color. This indicates a problem perceiving color, or color blindness. Interestingly, this condition is generally unknown to the patient until proven with a test. Color blindness is mainly found in males. If present in a female it may indicate ocular disease, in which case, an eye care professional should be consulted. If you struggle to distinguish between objects in dim light, it is a sign of possible night blindness.
A condition commonly found in elderly patients is cataracts, which have numerous telltale signs including: unclear vision that weakens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or details, the need for brighter light when reading, double or triple vision in one eye only painful puffiness around the eye, and a pale look to the usually dark pupil.
Throbbing pain in the eye, headaches, unclear vision, inflammation in the eye, colorful coronas around lights, nausea and vomiting are also signs of glaucoma, an acute medical condition, which requires prompt medical attention.
When it comes to children, it's useful to keep an eye out for weak eye movement, or eyes that cross in or out, which may indicate a vision problem known as strabismus. Specific things children might do, such as rubbing one or both eyes, squinting, head tilting, or needing to close one eye in order to see things better, can often indicate strabismus.
Though some conditions are more severe than others, anything that limits clear vision will be something that really affects your quality of life. A brief consultation with your optometrist can prevent unnecessary discomfort, or further eye problems.
