Poor vision in adults or children can be caused by a few conditions including anatomical changes in the eye, eye diseases, side effects due to medicine or eye injuries. Lots of people also suffer from visual disturbances resulting from aging or eye strain. These experiences can cause changes in your vision, which might sometimes cause discomfort and even make it harder to get through everyday activities, like reading fine print or working on a computer for long periods. Common symptoms of such vision problems include eye strain, headache, blurred vision, squinting and problems seeing at short or long distances.
Blurred vision is one of the most commonly occurring signs of a vision problem. If you have blurred vision when looking at faraway objects, you may be myopic or nearsighted. If you suffer from blurred vision when you're viewing anything at close range this may be a sign of farsightedness, or hyperopia. Blurred vision can also mean you have astigmatism due to an irregularity in the shape of the cornea, or sometimes the curvature of the lens inside the eye. No matter the reason you have blurry vision, it is vital that an eye doctor thoroughly check your vision and prescribe a solution to help clarify your sight.
A sudden onset of flashes of light, together with black floating spots and the sensation of a dark curtain or veil blocking a part of your vision indicates the chance of a retinal detachment. If this happens, visit your eye doctor right away, because it can have long-term consequences for your vision
Another sign of a vision problem is trouble distinguishing shades or intensity of color. This indicates a color perception problem, or color blindness. Color blindness is generally not known to the patient until discovered with a test. Color blindness is mostly something that affects males. If a woman has difficulty perceiving color it may represent ocular disease, and an optometrist needs to be consulted. For people who can't see objects in dim light, it is a sign of possible night blindness.
Cataracts, a condition commonly found in aging patients can have a number of warning signs which include: unclear sight 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, double or triple vision in one eye only redness around the eye, and a milky white appearance to the usually dark pupil.
Pulsing pain in the eye, headaches, unclear vision, redness in the eye, colorful halos around lights, nausea and vomiting are indicators of glaucoma, a serious medical illness, which needs medical attention.
When it comes to children, it's useful to keep an eye out for uncoordinated eye movement, or crossed eyes, which could indicate a condition known as strabismus. Certain things children might do, like rubbing one or both eyes, squinting, or the need to shut one eye to look at things better, often indicate strabismus.
If you are familiar with any of the symptoms mentioned here, make an appointment with your eye doctor as soon as possible. Even though some conditions are more problematic than others, any disruption to clear vision can be something that really affects your quality of life. A quick appointment with your optometrist can prevent unnecessary discomfort, or even more severe eye and vision problems.
