A decline in strong vision is usually due to a few factors including anatomical changes or defects in the eye or visual system, eye diseases, side effects due to medicine or eye injuries. Lots of people also report visual disturbances resulting from aging or eye stress. These experiences can lead to changes in your eyesight, which may cause pain and even make it harder to perform daily activities, like reading fine print or using a computer for extended periods of time. These vision problems can be expressed through the following symptoms: eye strain, headache, blurred vision, 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 looking at distant objects or signs, you might be nearsighted, or myopic. If you suffer from blurred vision when you're looking at objects nearby it could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism due to an irregularity in the way the cornea is formed, or the curvature of the lens inside the eye. In all cases of blurry vision, it is essential that an eye care professional examine your eyes 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 that limits a part of your vision indicates you might have what's known as a retinal detachment. In this case, see your eye doctor promptly, because this can have serious consequences for your eyesight.
Another common sign of a vision problem is trouble distinguishing different colors or brightness of color. This generally means the patient has a color perception problem, or color blindness. Color blindness is generally unknown to the patient until discovered by testing. Color blindness is mostly something that affects males. If a woman has problems perceiving color it could indicate ocular disease, in which case, an eye care professional should be consulted. For people who can't see objects in minimal light, it could mean the patient suffers from night blindness.
A problem frequently seen in older people is cataracts, which can have several indicating signs including: blurry sight that weakens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or details, colors that appear faded or yellowed, redness around the eye, and an opaque white appearance to the usually dark pupil.
Pulsing pain in the eye, headaches, blurred sight, redness in the eye, rainbow coronas around lights, nausea and vomiting are indicators of glaucoma, an acute medical illness, which needs immediate medical attention.
In children, it is important to keep an eye out for weak eye movement, or eyes that cross in or out, which may indicate a condition called strabismus. Specific behavior, like rubbing one or both eyes frequently, squinting, head tilting, or the need to shut one eye in order to look at things better, can often indicate strabismus.
If you experience any of the symptoms mentioned here, see your eye doctor promptly. While clearly some conditions may be more severe than others, any disruption to normal eyesight will be a burden, and impact your quality of life. A quick appointment with your optometrist can save you from being avoidably uncomfortable, not to mention even more severe eye and vision damage.
