A decline in strong vision is usually the result of a number of factors such as changes in the body or defects in the eye or visual system, eye diseases, side effects due to medicine or injuries to the eye. Commonly, people also report visual disturbances resulting from aging or eye strain. This can cause changes in your vision, which might sometimes cause discomfort and even make it harder to get through everyday activities, like reading books or looking at a computer screen for extended periods of time. These vision problems can be expressed through the following symptoms: blurry vision, headaches, eye strain, and struggling with close and far distances.
One of the most common signs of a vision problem can be blurred vision. If you suffer from blurred vision when focusing on faraway objects or signs, you could very well be myopic or nearsighted. If you suffer from blurred vision when you're viewing objects close by it may be a sign of farsightedness, or hyperopia. It can also be a sign of astigmatism which occurs 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's essential to have your optometrist examine your eyes and prescribe a solution to help clarify your sight.
Another sign of a vision problem is the inability to distinguish between shades or strength of color. This is an indication of a problem perceiving color, or color blindness. Color blindness is generally unknown to the patient until diagnosed by testing. Color blindness is generally something that affects males. If present in a female it could represent ocular disease, in which case, an optometrist should be consulted. For people who have difficulty distinguishing objects in minimal light, it could mean the patient suffers from night blindness.
Cataracts, a condition frequently seen aging people can have several warning signs which include: unclear vision that worsens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or details, muted or faded colors, improvement in near vision but a decline in distance vision, puffiness around the eye, and an opaque white appearance to the normally dark pupil.
Pulsing 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 calls for medical attention.
With younger patients, it is important to watch for weak eye movement, or eyes that cross in or out, which could indicate a vision problem called strabismus. Some things children might do, like rubbing one or both eyes frequently, squinting, or needing to close one eye to look at things better, often indicate strabismus.
If you have any of the symptoms we've mentioned here, see your eye doctor promptly. Though some conditions could be more severe than others, anything that restricts good sight can be something that compromises your quality of life. A short consultation with your optometrist can save you from unnecessary discomfort, or even more severe eye problems.
