In patients, whether young or old, sometimes poor vision can be the result of several possible factors such as anatomical changes or abnormalities in the eye, diseases affecting the eye, side effects caused by medication or eye injuries. Lots of people also report visual abnormalities resulting from aging or eye stress. These experiences can cause changes in your vision, which might sometimes cause pain and even make it harder to get through daily activities such as reading books or using a computer for long periods. Common signs and symptoms of such vision problems include blurry vision, headaches, eye strain, squinting and trouble seeing from short or long distances.
One of the most common signs of a vision problem can be blurred vision. If you suffer from blurred vision when you are looking at faraway objects or signs, you might very well have myopia, or be nearsighted. Blurred vision that's present when you are looking at something nearby may be a sign of farsightedness, or hyperopia. It can also be a sign of astigmatism which occurs due to a flaw in the way the cornea is formed, or the curvature of the lens inside the eye. Whatever the cause of blurry vision, it is essential that an eye doctor thoroughly check your eyes and decide on the most effective way to rectify your sight.
Another common indicator of a vision problem is trouble distinguishing shades or brightness of color. This generally means the patient has a color perception problem, or color blindness. Interestingly, this condition is usually unknown to the patient until diagnosed by testing. Color blindness is generally something that affects males. If present in a female it could mean she has ocular disease, and an eye doctor should be consulted. If you can't see objects in minimal light, it is a sign of possible night blindness.
A problem frequently seen in elderly people is cataracts, which can have a number of warning signs including: hazy vision that is worse in bright light, trouble seeing in the dark or reduced light, difficulty discerning small writing or details, the need for brighter light when reading, seeing duplicates in one eye, redness of the eye, and a pale look to the usually dark pupil.
Pulsing pain in the eye, headaches, blurry vision, redness in the eye, rainbow rings around lights, nausea and vomiting are also signs of glaucoma, a severe medical condition, which requires medical attention.
When it comes to children, we recommend you keep an eye out for uncoordinated eye movement, or eyes that cross in or out, which may indicate a condition known as strabismus. Some things children might do, such as rubbing one or both eyes, squinting, or the need to shut one eye to see things better, can often point to strabismus.
Even though some conditions are more severe than others, anything that restricts clear sight will be something that compromises your quality of life. A brief consultation with your optometrist can save you from being avoidably uncomfortable, or further eye and vision problems.
