Poor vision in adults or children can be the result of several possible conditions including changes in the body or defects in the eye or visual system, eye diseases, side effects due to medicine or injury. Lots of people also report visual abnormalities resulting from aging or eye stress. These experiences can result in changes in your vision, which might sometimes cause pain and even make it harder to get through normal activities such as reading books or using a computer for long periods. These vision problems can be expressed via the following symptoms: blurry vision, headaches, eye strain, squinting and struggling with short or long distances.
Blurred vision is one of the most oft-reported signs of a vision problem. If you suffer from blurred vision when focusing on distant objects, you might have myopia, or be nearsighted. If you suffer from blurred vision when you're looking at anything close by this could mean you suffer from hyperopia, or farsightedness. It can also be a sign of astigmatism because of an abnormality in the way the cornea is formed, or the curvature of the lens inside the eye. No matter the reason you have blurry vision, it's vital to have your eye doctor thoroughly check your vision and prescribe a solution to help clarify your sight.
A sudden onset of flashes of light, sometimes coupled with floating black spots and the feeling of a dark curtain that limits a portion of your vision indicates the chance of what's known as a retinal detachment. If this happens, visit your eye doctor as soon as you can, as it can have serious consequences.
Another warning sign of a vision problem is trouble distinguishing shades or strength of color. This generally means the patient has a problem perceiving color, or color blindness. Interestingly, this condition is usually not known to the patient until discovered via a consultation. Color blindness is mainly something that affects males. If present in a female it might indicate ocular disease, in which case, an optometrist should be consulted. For those who can't see objects in minimal light, it is a sign of possible night blindness.
An issue commonly found in aging people is cataracts, which have a number of warning signs including: blurry vision that worsens in bright light, weak night vision, difficulty discerning small writing or objects, muted or faded colors, double or triple vision in one eye only redness around the eye, and an opaque white appearance to the normally dark pupil.
Pulsing eye pain, headaches, unclear sight, redness in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, a serious medical illness, which requires prompt medical attention.
With younger patients, it is important to watch for uncoordinated eye movement, or crossed eyes, which may indicate a condition called strabismus. Certain things children might do, like rubbing eyes, squinting, head tilting, or the need to shut one eye in order to see things better, can often point to strabismus.
If you are familiar with any of the symptoms mentioned here, make an appointment with your eye doctor as soon as possible. Though some conditions may be more problematic than others, anything that restricts normal eyesight can be a burden, and impact your quality of life. A brief appointment with your optometrist can prevent unnecessary discomfort, not to mention further eye problems.
