In patients, whether young or old, sometimes poor vision can be due to a few factors such as anatomical changes or irregularities in the eye, diseases affecting the eye, side effects caused by medication or injuries to the eye. Lots of people also experience visual abnormalities due to aging or eye strain. These experiences can result in changes in your vision, which can cause pain and even make it harder to get through everyday activities, like reading fine print or looking at a computer screen for extended periods of time. Common signs and symptoms of such vision problems include blurry vision, headaches, eye strain, squinting and struggling with close and far distances.
One of the most common signs of a vision problem can be blurred vision. If you have blurred vision when you're looking at distant objects, you might very well have myopia, or be nearsighted. Blurred vision that's present when you are looking at anything nearby could mean you suffer from hyperopia, or farsightedness. Blurred vision can also mean you have astigmatism which occurs due to an irregularity in the way the cornea is formed. In all cases of blurry vision, it is essential that an eye care professional examine your eyes and decide on the most effective way to improve your sight.
Another common sign of a vision problem is difficulty discerning different colors or intensity of color. This generally means the patient has a color perception problem, or color blindness. Color blindness is usually not known to the patient until diagnosed with a test. Color blindness is mainly something that affects males. If present in a female it could mean she has ocular disease, and an optometrist should be consulted. For people who can't see objects in minimal light, it is a sign of possible night blindness.
An issue commonly found in older people is cataracts, which can have a number of warning signs including: hazy vision that weakens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or objects, colors that appear faded or yellowed, double or triple vision in one eye only painful puffiness around the eye, and a pale appearance to the usually dark pupil.
Throbbing pain in the eye, headaches, blurry vision, inflammation in the eye, colorful coronas around lights, nausea and vomiting are also signs of glaucoma, an acute medical condition, which calls for prompt medical attention.
With younger patients, it's useful to keep an eye out for weak eye movement, or eyes that cross in or out, which could indicate a condition called strabismus. Specific things children might do, such as rubbing eyes, squinting, or needing to close one eye in order to look at things better, often indicate this issue.
Though some conditions may be more severe than others, anything that restricts clear sight can be something that compromises your quality of life. A quick visit to your optometrist can save you from being avoidably uncomfortable, or even more severe eye damage.
