Often, when either children an adults experience poor vision, it can be caused by a number of conditions including anatomical changes or defects in the eye, diseases affecting the eye, side effects of medication or injuries to the eye. Many people also report visual disturbances associated with age or eye stress. Aging and stress can lead to changes in your eyesight, which might sometimes make it uncomfortable or difficult to perform daily activities such as reading the newspaper or using a computer for extended periods of time. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, squinting and problems seeing at short or long distances.
Blurred vision is one of the most common signs of a vision problem. If you have blurred vision when looking at faraway objects, you could very well be nearsighted, or myopic. Blurred vision that's present when you are looking at objects close by may be a sign of farsightedness, or hyperopia. Blurred vision can also be a sign of astigmatism due to an irregularity in the shape of the cornea. Whatever the cause of blurry vision, it's vital that an eye care professional thoroughly check your eyes and prescribe a solution to help clarify your sight.
Sudden flashes of light, sometimes coupled with black floating spots and the feeling of a dark curtain or veil inhabiting a portion of your vision indicates the possibility of what's known as a retinal detachment. If this is the case, see your eye doctor promptly, as it can have severe consequences for your vision
Another indicator of a vision problem is trouble distinguishing shades or intensity of color. This indicates a color perception problem, or color blindness. Interestingly, this condition is often unknown to the patient until diagnosed by testing. Color blindness is mainly something that affects males. If a woman has difficulty seeing color it may represent ocular disease, and an optometrist needs to be consulted. For people who can't see objects in low light, it is a sign of possible night blindness.
Cataracts, a condition frequently seen older patients can have numerous telltale signs including: blurry sight that weakens in bright light, weak night vision, trouble discerning small writing or objects, colors that appear faded or yellowed, seeing duplicates in one eye, painful redness around the eye, and an opaque white look to the normally dark pupil.
Throbbing eye pain, headaches, blurry sight, redness in the eye, rainbow coronas around lights, nausea and vomiting are indicators of glaucoma, a severe medical condition, which needs prompt medical attention.
With younger patients, we recommend you keep an eye out for uncoordinated eye movement, or crossed eyes, which could indicate a vision problem known as strabismus. Certain things children might do, such as rubbing eyes frequently, squinting, head tilting, or needing to close one eye to focus better, often point to strabismus.
If you have any of the symptoms listed here, make an appointment with your eye doctor as soon as possible. While clearly some conditions could be more severe than others, anything that limits normal eyesight will be something that compromises your quality of life. A brief consultation with your optometrist can prevent unnecessary discomfort, not to mention even more severe eye damage.
