Poor Vision: Know The Signs

In patients, whether young or old, sometimes poor vision can be due to several possible conditions including changes in the body or in the eye or visual system, diseases affecting the eye, side effects caused by medicine or eye injuries. Many people also experience visual abnormalities due to aging or eye stress. Aging and stress can result in changes in your eyesight, which might cause discomfort and even make it harder to get through daily activities, like reading fine print 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 trouble seeing from short or long distances.

One of the first signs of a vision problem can be blurred vision. If you suffer from blurred vision when you're looking at distant objects or signs, you may very well be nearsighted, or myopic. Blurred vision that's present when you are looking at objects at close range could mean you suffer from hyperopia, or farsightedness. Blurred vision can also mean you have astigmatism because of an irregularity in the way the cornea is formed, or sometimes the curvature of the lens inside the eye. No matter the reason you have blurry vision, it's essential to have your eye doctor thoroughly check your vision and decide on the most effective way to rectify your sight.

Another warning sign of a vision problem is difficulty discerning different colors or strength of color. This generally means the patient has a color perception problem, or color blindness. Interestingly, this condition is usually not known to the patient until proven by testing. Color blindness is generally found in males. If present in a female it might mean she has ocular disease, and an eye doctor should be consulted. For people who have difficulty distinguishing objects in minimal light, it is a sign of possible night blindness.

A problem frequently seen in aging people is cataracts, which have numerous warning signs including: hazy sight that is worse in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or details, muted or faded colors, improvement in near vision but a decline in distance vision, painful puffiness of the eye, and a milky white appearance to the normally dark pupil.

Throbbing eye pain, headaches, unclear vision, inflammation in the eye, colorful halos around lights, nausea and vomiting are indicators of glaucoma, an acute medical condition, which requires immediate medical attention.

In children, it is important to look out for weak eye movement, or crossed eyes, which could indicate a vision problem called strabismus. Some behavior, like rubbing one or both eyes frequently, squinting, or needing to close one eye to focus better, often indicate strabismus.

If you are familiar with any of the symptoms listed here, make an appointment with your eye doctor promptly. Even though some conditions could be more serious than others, anything that restricts clear sight will be something that really affects your quality of life. A short consultation with your optometrist can save you from being avoidably uncomfortable, or even more severe eye problems.
