Often, when either children an adults experience poor vision, it can be caused by a few conditions such as anatomical changes in the eye, diseases affecting the eye, side effects due to medicine or injuries to the eye. Commonly, people also experience visual disturbances associated with age or eye strain. This can result in changes in your eyesight, which might cause pain and even make it harder to get through daily activities such as reading books or looking at a computer screen for extended periods of time. These vision problems can be expressed through the following symptoms: eye strain, headache, blurred vision, and problems seeing at close and far distances.
One of the first signs of a vision problem can be blurred vision. If you suffer from blurred vision when looking at faraway objects, you could be nearsighted, or myopic. If you have blurred vision when you're viewing objects nearby it could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism 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 is really important to have your eye care professional 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 brightness of color. This generally means the patient has color blindness. Color blindness is often unknown to the patient until proven by testing. Color blindness is generally something that affects males. If a woman has problems seeing color it might mean she has ocular disease, and an eye doctor needs to be consulted. For those who can't see objects in minimal light, it is a sign of possible night blindness.
A condition frequently seen in elderly patients is cataracts, which can have several indicating signs which include: blurry vision that worsens in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or objects, the need for brighter light when reading, improvement in near vision while distance vision worsens, painful inflammation around the eye, and an opaque white look to the usually dark pupil.
Throbbing pain in the eye, headaches, unclear sight, redness in the eye, colorful coronas around lights, nausea and vomiting are indicators of glaucoma, a serious medical condition, which requires immediate medical attention.
With younger patients, we recommend you look out for weak eye movement, or crossed eyes, which could indicate a condition called strabismus. Specific things children might do, such as rubbing one or both eyes, squinting, head tilting, or the need to shut one eye in order to see things better, can often point to this issue.
If you experience any of the symptoms listed here, visit your eye doctor promptly. Though some conditions are more problematic than others, anything that restricts good vision can be a burden, and impact your quality of life. A brief consultation with your optometrist can save you from unnecessary discomfort, not to mention further eye problems.
