Poor vision in adults or children can be due to a number of conditions including anatomical changes in the eye or visual system, eye diseases, side effects caused by medication or injuries to the eye. Commonly, people also experience visual disturbances due to aging or eye stress. This can lead to changes in your eyesight, which may cause pain and even make it harder to get through daily activities such as reading books or looking at a computer screen for long periods. These vision problems can be expressed via the following symptoms: blurry vision, headaches, eye strain, squinting and struggling with short or long distances.
Blurred vision is one of the most commonly occurring signs of a vision problem. If you report blurred vision when looking at distant objects, you could very well be myopic or nearsighted. If you have blurred vision when you're looking at objects nearby it may be a sign of hyperopia, or farsightedness. It can also be a symptom of astigmatism which occurs because of an irregularity in the shape of the cornea, or the curvature of the lens inside the eye. No matter the reason you have blurry vision, it's vital to have your eye care professional thoroughly check your eyes and decide on the best way to improve your sight.
Another common indicator of a vision problem is difficulty discerning shades or brightness of color. This generally means the patient has color blindness. Interestingly, this condition is usually unknown to the patient until discovered via a consultation. Color blindness is generally something that affects males. If present in a female it may mean she has ocular disease, in which case, an eye doctor 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 several warning signs which include: unclear vision that is worse in bright light, weak night vision, trouble seeing small writing or objects, colors that appear faded or yellowed, double or triple vision in one eye only painful inflammation around the eye, and a pale appearance to the normally dark pupil.
Pulsing pain in the eye, headaches, unclear sight, redness in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, an acute medical condition, which needs prompt medical attention.
With younger patients, we recommend you keep an eye out for weak eye movement, or eyes that cross in or out, which could indicate a condition known as strabismus. Specific behavior, such as rubbing one or both eyes, squinting, or the need to close one eye in order to look at things better, can often indicate strabismus.
Even though some conditions could be more severe than others, any disruption to good vision will be something that really affects your quality of life. A brief consultation with your optometrist can prevent unnecessary discomfort, not to mention even more severe eye damage.
