A decline in strong vision is usually due to a few factors including changes in the body or defects in the eye, diseases affecting the eye, side effects due to medication or injuries to the eye. Commonly, people also report visual disturbances associated with age or eye stress. Aging and stress can cause changes in your eyesight, which can sometimes make it painful or difficult to perform daily activities such as reading fine print or working on a computer for extended periods of time. Common signs and symptoms of these types of vision problems include eye strain, headache, blurred vision, and problems seeing at short or long distances.
One of the first signs of a vision problem can be blurred vision. If you report blurred vision when you're focusing on distant objects or signs, you may have myopia, or be nearsighted. If you suffer from blurred vision when you're viewing anything at close range this may be a sign of hyperopia, or farsightedness. It can also be a symptom of astigmatism because of an irregularity in the shape of the cornea, or the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's really important to have your eye care professional examine your eyes and decide on the best way to rectify your sight.
A sudden onset of flashes of light, sometimes coupled with floating black spots and the sensation of a dark curtain blocking a portion of your vision indicates the possibility of what's known as a retinal detachment. In this case, make an appointment to see your eye doctor right away, as it can have long-term consequences for your vision
Another sign of a vision problem is difficulty discerning shades or brightness of color. This is an indication of a problem perceiving color, or color blindness. Color vision defects are often unknown to the patient until diagnosed with a test. Color blindness is mostly found in males. If a woman has difficulty seeing color it may indicate ocular disease, and an eye care professional needs to be consulted. For people who can't see objects in low light, it could mean the patient suffers from night blindness.
A problem frequently seen in elderly people is cataracts, which have numerous indicating signs including: blurry vision that weakens in bright light, trouble seeing in the dark or reduced light, difficulty seeing small writing or details, the need for brighter light when reading, unexpected improvement in near vision but a decline in distance vision, puffiness around the eye, and a milky white appearance to the usually dark pupil.
Pulsing eye pain, headaches, blurry sight, redness in the eye, rainbow rings around lights, nausea and vomiting are also signs of glaucoma, an acute medical condition, which needs immediate medical attention.
When it comes to children, it is important to look out for weak eye movement, or crossed eyes, which could indicate a condition known as strabismus. Some things children might do, such as rubbing eyes, squinting, or the need to shut one eye in order to focus better, can often point to this issue.
Though some conditions are more serious than others, anything that limits good eyesight will be a burden, and impact your quality of life. A brief visit to your optometrist can save you from unnecessary discomfort, not to mention even more severe eye and vision damage.
