Poor vision in adults or children can be the result of several possible conditions including changes in the body or in the eye, eye diseases, side effects due to medicine or injuries to the eye. Many people also suffer from visual disturbances resulting from aging or eye stress. Aging and stress can result in changes in your vision, which can make it uncomfortable or difficult to get through daily activities such as reading fine print or using a computer for long periods. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, and trouble seeing from short or long distances.
Blurred vision is one of the most oft-reported signs of a vision problem. If you report blurred vision when you're focusing on distant objects or signs, you could very well have myopia, or be nearsighted. Blurred vision that's present when you are looking at something close by may be a sign of farsightedness, or hyperopia. It can also mean you have astigmatism because of a flaw 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 really important to have your eye care professional thoroughly check your vision and decide on the most effective way to improve your sight.
Rapid flashes of light, sometimes coupled with floating black spots and the sensation of a dark curtain blocking a section of your vision indicates the possibility of what's known as a retinal detachment. If this is the case, visit your eye doctor as soon as you can, as it can have severe consequences.
Another indicator of a vision problem is the inability to distinguish between shades or strength of color. This indicates a color perception problem, or color blindness. Color blindness is generally not known to the patient until discovered by testing. Color blindness is generally found in males. If a woman has difficulty seeing color it might indicate ocular disease, and an optometrist should be consulted. If you have difficulty distinguishing objects in minimal light, it is a sign of possible night blindness.
Cataracts, a condition frequently seen aging people can have several telltale signs which include: hazy vision that weakens in bright light, weak night vision, trouble seeing small writing or details, muted or faded colors, double or triple vision in one eye only puffiness around the eye, and a milky white look to the normally dark pupil.
Throbbing eye pain, headaches, blurry sight, inflammation in the eye, colorful coronas around lights, nausea and vomiting are indicators of glaucoma, an acute medical illness, which calls for medical attention.
When it comes to children, it is important to look out for weak eye movement, or crossed eyes, which may indicate a condition known as strabismus. Some behavior, such as rubbing eyes frequently, squinting, or needing to shut one eye in order to focus better, can often point to this issue.
While clearly some conditions may be more severe than others, anything that limits good sight will be something that compromises your quality of life. A brief consultation with your optometrist can save you from unnecessary discomfort, or further eye problems.
