In patients, whether young or old, sometimes poor vision can be the result of a few conditions including changes in the body or abnormalities in the eye or visual system, diseases affecting the eye, side effects due to medication or injuries to the eye. Commonly, people also experience visual abnormalities due to aging or eye stress. These experiences can cause changes in your eyesight, which may make it painful or difficult to get through daily activities such as reading fine print or looking at a computer screen for long periods. These vision problems can be expressed through the following symptoms: blurry vision, headaches, eye strain, and struggling with close and far distances.
Blurred vision is one of the most oft-reported signs of a vision problem. If you have blurred vision when focusing on faraway objects or signs, you could very well be nearsighted, or myopic. Blurred vision that's present when you are looking at anything nearby may be a sign of farsightedness, or hyperopia. Blurred vision can also mean you have astigmatism due to an abnormality in the way the cornea is formed, or the curvature of the lens inside the eye. In all cases of blurry vision, it is vital to have your eye care professional examine your eyes and prescribe a solution to help clarify your sight.
Another common sign of a vision problem is difficulty discerning different colors or brightness of color. This is an indication of color blindness. Color blindness is often unknown to the patient until discovered with a test. Color blindness is generally something that affects males. If a woman has problems perceiving color it may indicate ocular disease, and an eye care professional needs to be consulted. For people who struggle to distinguish between objects in dim light, it is a sign of possible night blindness.
Cataracts, a condition frequently seen older people can have a number of indicating signs including: unclear vision that is worse in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or objects, colors that appear faded or yellowed, improvement in near vision but a decline in distance vision, redness of the eye, and a milky white appearance to the normally dark pupil.
Pulsing eye pain, headaches, unclear sight, inflammation in the eye, rainbow coronas around lights, nausea and vomiting are also signs of glaucoma, a serious medical condition, which calls for prompt medical attention.
In children, we recommend you keep an eye out for weak eye movement, or crossed eyes, which could indicate a vision problem known as strabismus. Specific behavior, like rubbing eyes, squinting, or needing to close one eye to focus better, can often point to this issue.
If you are familiar with any of the symptoms we've mentioned here, see your eye doctor promptly. Though some conditions could be more serious than others, anything that restricts good vision will be something that compromises your quality of life. A quick consultation with your optometrist can prevent being avoidably uncomfortable, or further eye damage.
