A decline in strong vision is usually due to a few conditions including anatomical changes or defects in the eye or visual system, eye diseases, side effects due to medication or eye injuries. Many people also report visual abnormalities resulting from aging or eye strain. Aging and stress can lead to changes in your vision, which may make it painful or difficult to get through normal 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, and trouble seeing from short or long distances.
One of the most common signs of a vision problem can be blurred vision. If you report blurred vision when you're focusing on distant objects or signs, you could be myopic or nearsighted. Blurred vision that's present when you are looking at something at close range may be a sign of hyperopia, or farsightedness. Blurred vision can also be a sign of astigmatism which occurs because of an irregularity in the shape of the cornea, or the curvature of the lens inside the eye. In all cases of blurry vision, it's essential to have your eye care professional thoroughly check your eyes and prescribe a solution to help clarify your sight.
Another warning sign of a vision problem is the inability to distinguish between different colors or brightness of color. This indicates a color perception problem, or color blindness. Color blindness is usually not known to the patient until diagnosed by testing. Color blindness is mainly found in males. If present in a female it might mean she has ocular disease, in which case, an eye care professional needs to be consulted. For people who can't see objects in low light, it could mean the patient suffers from night blindness.
A problem commonly found in elderly patients is cataracts, which can have numerous indicating signs including: unclear sight that weakens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or details, the need for brighter light when reading, unexpected improvement in near vision but a decline in distance vision, puffiness of the eye, and a pale look to the normally dark pupil.
Throbbing pain in the eye, headaches, unclear sight, redness in the eye, colorful rings around lights, nausea and vomiting are also signs of glaucoma, a severe medical illness, which needs prompt medical attention.
With younger patients, it is important to look out for uncoordinated eye movement, or eyes that cross in or out, which could indicate a condition called strabismus. Certain things children might do, such as rubbing one or both eyes, squinting, or needing to close one eye to see things better, can often indicate strabismus.
If you are familiar with any of the symptoms we've mentioned here, make an appointment with your eye doctor promptly. Even though some conditions are more problematic than others, anything that restricts good eyesight can be something that really affects your quality of life. A quick appointment with your optometrist can save you from unnecessary discomfort, not to mention even more severe eye and vision damage.
