A decline in strong vision is usually the result of a few factors including changes in the body or defects in the eye, eye diseases, side effects of medicine or injuries to the eye. Many people also suffer from visual disturbances resulting from aging or eye stress. These experiences can lead to changes in your eyesight, which can sometimes make it uncomfortable or difficult to get through normal activities, like reading fine print or using a computer for extended periods of time. Common symptoms of these types of vision problems include eye strain, headache, blurred vision, squinting and trouble seeing from short or long distances.
Blurred vision is one of the most oft-reported signs of a vision problem. If you report blurred vision when you're looking at distant objects or signs, you might very well be nearsighted, or myopic. Blurred vision that's present when you are looking at anything close by may be a sign of farsightedness, or hyperopia. Blurred vision can also be a symptom of astigmatism which occurs because of a flaw in the way the cornea is formed, or the curvature of the lens inside the eye. In all cases of blurry vision, it's really important to have your eye care professional thoroughly check your vision and decide on the most effective way to improve your sight.
Rapid flashes of light, sometimes coupled with floating black spots and what may feel like a dark curtain or veil blocking a section of your vision indicates the possibility of a retinal detachment. In this case, see your eye doctor promptly, as it can have serious consequences.
Another common indicator of a vision problem is trouble distinguishing shades or brightness of color. This indicates color blindness. Color vision defects are generally unknown to the patient until discovered with a test. Color blindness is mostly something that affects males. If present in a female it may represent ocular disease, in which case, an optometrist needs to be consulted. For those who struggle to distinguish between objects in minimal light, it is a sign of possible night blindness.
Cataracts, a condition commonly found in older patients have several telltale signs including: blurry sight that worsens in bright light, trouble seeing in the dark or reduced light, trouble discerning small writing or objects, the need for brighter light when reading, improvement in near vision but a decline in distance vision, painful redness of the eye, and an opaque white look to the normally dark pupil.
Pulsing pain in the eye, headaches, blurry sight, inflammation in the eye, colorful halos around lights, nausea and vomiting are indicators of glaucoma, a serious medical illness, which calls for medical attention.
When it comes to children, we recommend you watch for uncoordinated eye movement, or eyes that cross in or out, which could indicate a vision problem called strabismus. Some behavior, such as rubbing one or both eyes, squinting, or the need to shut one eye to focus better, often point to this issue.
If you are familiar with any of the symptoms we've mentioned here, see your eye doctor promptly. Even though some conditions are more severe than others, anything that limits normal vision can be something that compromises your quality of life. A short visit to your optometrist can save you from unnecessary discomfort, or further eye and vision damage.
