Often, when either children an adults experience poor vision, it can be caused by a few factors such as changes in the body or defects in the eye, diseases affecting the eye, side effects due to medication or injury. Commonly, people also suffer from visual disturbances due to aging or eye stress. This can result in changes in your eyesight, which might cause discomfort and even make it harder to perform everyday activities, like reading books or using a computer for extended periods of time. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, and trouble seeing from close and far distances.
One of the first signs of a vision problem can be blurred vision. If you have blurred vision when focusing on distant objects, you could have myopia, or be nearsighted. Blurred vision that's present when you are looking at something at close range could mean you suffer from farsightedness, or hyperopia. It can also be a sign of astigmatism because of an abnormality in the way the cornea is formed, or sometimes the curvature of the lens inside the eye. In all cases of blurry vision, it is essential that an eye care professional examine your eyes and decide on the best way to improve your sight.
Another common indicator of a vision problem is difficulty discerning shades or strength of color. This generally means the patient has a problem perceiving color, or color blindness. Interestingly, this condition is often unknown to the patient until proven with a test. Color blindness is mostly something that affects males. If present in a female it might mean she has ocular disease, and an eye care professional needs to be consulted. For those who struggle to distinguish between objects in minimal light, it could mean the patient suffers from night blindness.
Cataracts, a condition commonly found in elderly patients have several indicating signs which include: blurry sight that worsens in bright light, weak night vision, difficulty discerning small writing or details, the need for brighter light when reading, seeing duplicates in one eye, painful puffiness of the eye, and a pale look to the usually dark pupil.
Throbbing pain in the eye, headaches, blurred vision, inflammation in the eye, colorful rings around lights, nausea and vomiting are indicators of glaucoma, a severe medical illness, which requires medical attention.
When it comes to children, we recommend you keep an eye out for uncoordinated eye movement, or crossed eyes, which may indicate a condition known as strabismus. Some behavior, such as rubbing one or both eyes frequently, squinting, head tilting, or the need to close one eye in order to look at things better, often point to this issue.
If you are familiar with any of the symptoms listed here, visit your eye doctor as soon as possible. Though some conditions could be more severe than others, anything that restricts clear vision will be something that compromises your quality of life. A quick appointment with your optometrist can prevent unnecessary discomfort, or further eye and vision damage.
