Often, when either children an adults experience poor vision, it can be the result of several possible factors including anatomical changes or irregularities in the eye, diseases affecting the eye, side effects of medicine or eye injuries. Many people also report visual abnormalities associated with age or eye stress. This can cause changes in your vision, which might sometimes cause discomfort and even make it harder to perform normal activities such as reading books or using a computer for long periods. Common signs and symptoms of such vision problems include eye strain, headache, blurred vision, and trouble seeing from close and far distances.
Blurred vision is one of the most commonly occurring signs of a vision problem. If you have blurred vision when you are focusing on distant objects or signs, you could very well be myopic or nearsighted. If you suffer from blurred vision when you're viewing objects nearby it could mean you suffer from hyperopia, or farsightedness. It can also be a symptom of astigmatism which occurs because of an irregularity in the shape of the cornea, or sometimes the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's vital that an optometrist thoroughly check your eyes and decide on the best way to improve your sight.
A sudden onset of flashes of light, together with black floating spots and what may feel like a dark curtain or veil inhabiting a portion of your vision indicates you might have what's known as a retinal detachment. In this case, visit your eye doctor promptly, as it can have long-term consequences for your eyesight.
Another common sign of a vision problem is difficulty discerning shades or intensity of color. This generally means the patient has a color perception problem, or color blindness. Color vision defects are generally unknown to the patient until discovered via a consultation. Color blindness is mostly found in males. If present in a female it could indicate ocular disease, in which case, an eye doctor should be consulted. If you have difficulty distinguishing objects in low light, it could mean the patient suffers from night blindness.
Cataracts, a condition frequently seen elderly patients can have numerous telltale signs including: hazy vision that worsens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or objects, the need for brighter light when reading, improvement in near vision while distance vision worsens, painful redness of the eye, and an opaque white look to the normally dark pupil.
Throbbing pain in the eye, headaches, unclear sight, inflammation in the eye, rainbow halos around lights, nausea and vomiting are also signs of glaucoma, a severe medical condition, which needs 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 could indicate a condition known as strabismus. Some behavior in children, such as rubbing eyes, squinting, head tilting, or the need to shut one eye to look at things better, can often indicate this issue.
If you have any of the symptoms we've mentioned here, see your eye doctor as soon as possible. Though some conditions could be more serious than others, anything that restricts clear eyesight can be a burden, and impact your quality of life. A short visit to your optometrist can prevent being avoidably uncomfortable, not to mention further eye damage.
