A decline in strong vision is usually due to a number of conditions including changes in the body or abnormalities in the eye, diseases affecting the eye, side effects due to medication or injuries to the eye. Lots of people also experience visual abnormalities resulting from aging or eye stress. This can result in changes in your vision, which can sometimes cause pain and even make it harder to get through everyday activities, like reading books or using a computer for long periods. These vision problems can be expressed via the following symptoms: blurry vision, headaches, eye strain, squinting and problems seeing at short or long distances.
One of the most common 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 could very well be myopic or nearsighted. Blurred vision that's present when you are looking at something at close range could mean you suffer from hyperopia, or farsightedness. Blurred vision can also be a symptom of astigmatism because of an irregularity in the way the cornea is formed, or sometimes the curvature of the lens inside the eye. Whatever the cause of blurry vision, it's really important that an eye care professional examine your eyes and decide on the most effective way to rectify your sight.
Rapid flashes of light, often combined with black floating spots and the sensation of a dark curtain or veil inhabiting a part of your vision indicates the possibility of what's known as a retinal detachment. If this is the case, make an appointment to see your eye doctor as soon as you can, because this can have serious consequences.
Another common sign of a vision problem is trouble distinguishing shades or brightness of color. This is an indication of a problem perceiving color, or color blindness. Interestingly, this condition is generally unknown to the patient until discovered via a consultation. Color blindness is generally found in males. If present in a female it could represent ocular disease, and an optometrist should be consulted. For people who have difficulty distinguishing objects in low light, it could mean the patient suffers from night blindness.
An issue frequently seen in older patients is cataracts, which can have several telltale signs including: hazy sight that weakens in bright light, trouble seeing in the dark or reduced light, difficulty discerning small writing or details, the need for brighter light when reading, improvement in near vision while distance vision worsens, painful inflammation around the eye, and a pale look to the normally dark pupil.
Pulsing pain in the eye, headaches, unclear sight, redness in the eye, colorful rings around lights, nausea and vomiting are indicators of glaucoma, an acute medical illness, which needs prompt medical attention.
In children, we recommend you look out for weak eye movement, or crossed eyes, which could indicate a vision problem known as strabismus. Specific behavior, such as rubbing eyes, squinting, head tilting, or needing to close one eye in order to see things better, can often indicate strabismus.
While clearly some conditions could be more serious than others, anything that restricts good vision can be a burden, and impact your quality of life. A short appointment with your optometrist can save you from being avoidably uncomfortable, or further eye damage.
