A decline in strong vision is usually the result of a number of conditions including anatomical changes or defects in the eye, diseases affecting the eye, side effects of medication or injury. Commonly, people also suffer from visual disturbances due to aging or eye strain. Aging and stress can lead to changes in your vision, which might cause pain and even make it harder to get through normal activities, like reading the newspaper or looking at a computer screen for extended periods of time. These vision problems can be expressed through the following symptoms: blurry vision, headaches, eye strain, and struggling with short or long distances.
Blurred vision is one of the most commonly occurring signs of a vision problem. If you suffer from blurred vision when you are focusing on distant objects, you could be nearsighted, or myopic. Blurred vision that's present when you are looking at objects nearby could mean you suffer from farsightedness, or hyperopia. Blurred vision can also mean you have astigmatism which occurs because of an irregularity in the shape of the cornea. Whatever the cause of blurry vision, it's essential to have your eye care professional thoroughly check your vision and prescribe a solution to help clarify your sight.
A sudden onset of flashes of light, often combined with floating black spots and the feeling of a dark curtain or veil blocking a portion of your vision indicates you might have what's known as a retinal detachment. In this case, make an appointment to see your eye doctor promptly, because this can have serious consequences.
Another indicator of a vision problem is the inability to distinguish between shades or strength of color. This indicates a problem perceiving color, or color blindness. Interestingly, this condition is often unknown to the patient until diagnosed by testing. Color blindness is mostly found in males. If present in a female it could mean she has ocular disease, and an optometrist needs to be consulted. If you have difficulty distinguishing objects in dim light, it could mean the patient suffers from night blindness.
Cataracts, a condition frequently seen aging people have several warning signs including: unclear vision that is worse in bright light, weak night vision, trouble seeing small writing or objects, colors that appear faded or yellowed, double or triple vision in one eye only puffiness around the eye, and an opaque white look to the normally dark pupil.
Throbbing eye pain, headaches, blurred sight, redness in the eye, rainbow coronas around lights, nausea and vomiting are indicators of glaucoma, an acute medical illness, which needs immediate medical attention.
In children, it's useful to keep an eye out for weak eye movement, or eyes that cross in or out, which could indicate a vision problem called strabismus. Specific behavior in children, such as rubbing eyes frequently, squinting, or the need to shut one eye to look at things better, can often point to strabismus.
While clearly some conditions are more problematic than others, anything that limits normal vision will be something that really affects your quality of life. A brief visit to your optometrist can save you from unnecessary discomfort, not to mention further eye and vision problems.
