A decline in strong vision is usually the result of a few conditions such as changes in the body or defects in the eye, diseases affecting the eye, side effects of medicine or injury. Commonly, people also experience visual abnormalities due to aging or eye strain. These experiences can result in changes in your vision, which may sometimes make it painful or difficult to perform normal activities, like reading fine print or looking at a computer screen for extended periods of time. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, squinting and problems seeing at close and far 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, you may be nearsighted, or myopic. If you have blurred vision when you're looking at something close by it may be a sign of farsightedness, or hyperopia. Blurred vision can also be a sign of astigmatism which occurs because of an irregularity in the shape of the cornea. In all cases of blurry vision, it is really important to have your eye care professional thoroughly check your vision and prescribe a solution to help clarify your sight.
Sudden flashes of light, together with floating black spots and what may feel like a dark curtain or veil blocking a part of your vision indicates you might have what's known as a retinal detachment. In this case, visit your eye doctor as soon as you can, as this can have long-term consequences.
Another sign of a vision problem is the inability to distinguish between shades or brightness of color. This indicates a problem perceiving color, or color blindness. Color blindness is usually unknown to the patient until diagnosed via a consultation. Color blindness is generally found in males. If a woman has difficulty seeing color it may represent ocular disease, in which case, an optometrist should be consulted. For people who struggle to distinguish between objects in minimal light, it is a sign of possible night blindness.
A problem frequently seen in elderly patients is cataracts, which have numerous telltale signs which include: hazy sight that weakens in bright light, weak night vision, trouble discerning small writing or details, muted or faded colors, painful redness of the eye, and a milky white look to the usually dark pupil.
Throbbing pain in the eye, headaches, blurry sight, inflammation in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, a severe medical condition, which requires prompt medical attention.
With younger patients, it's useful to watch for weak eye movement, or crossed eyes, which may indicate a vision problem known as strabismus. Some things children might do, such as rubbing eyes frequently, squinting, or the need to shut one eye to look at things better, often point to this issue.
If you experience any of the symptoms mentioned here, visit your eye doctor promptly. Even though some conditions may be more serious than others, anything that restricts good sight can be something that really affects your quality of life. An eye examination with your optometrist can prevent unnecessary discomfort, or even more severe eye problems.
