In patients, whether young or old, sometimes poor vision can be the result of a few factors such as anatomical changes in the eye or visual system, diseases affecting the eye, side effects due to medicine or eye injuries. Lots of people also report visual abnormalities due to aging or eye strain. Aging and stress can cause changes in your vision, which can make it painful or difficult to perform everyday activities such as reading the newspaper or using a computer for extended periods of time. These vision problems can be expressed through the following symptoms: eye strain, headache, blurred vision, and trouble seeing from short or long distances.
One of the first signs of a vision problem can be blurred vision. If you report blurred vision when you are focusing on faraway objects or signs, you might very well be nearsighted, or myopic. Blurred vision that's present when you are looking at objects at close range may be a sign of hyperopia, or farsightedness. It can also be a sign of astigmatism which occurs 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 optometrist examine your vision and prescribe a solution to help clarify your sight.
Sudden flashes of light, often combined with black floating spots and the feeling of a dark curtain that limits a portion of your vision indicates you might have what's known as a retinal detachment. If this is the case, visit your eye doctor as soon as you can, as this can have severe consequences for your vision
Another indicator of a vision problem is the inability to distinguish between different colors or intensity of color. This indicates color blindness. Interestingly, this condition is usually not known to the patient until proven via a consultation. Color blindness is mostly found in males. If a woman has difficulty perceiving color it may represent ocular disease, in which case, an eye care professional needs to be consulted. For those who struggle to distinguish between objects in minimal light, it could mean the patient suffers from night blindness.
Cataracts, a condition commonly found in aging patients have several telltale signs including: hazy vision that weakens in bright light, weak night vision, trouble discerning small writing or objects, the need for brighter light when reading, improvement in near vision while distance vision worsens, painful inflammation of the eye, and a pale look to the normally dark pupil.
Throbbing eye pain, 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 is important to keep an eye out for weak eye movement, or crossed eyes, which may indicate a condition known as strabismus. Some behavior, such as rubbing one or both eyes, squinting, or needing to close one eye in order to look at things better, can often indicate this issue.
Even though some conditions are more problematic than others, any disruption to normal eyesight will be something that compromises your quality of life. A quick visit to your optometrist can prevent being avoidably uncomfortable, or even more severe eye damage.
