Poor vision in adults or children can be due to a few conditions including changes in the body or in the eye, diseases affecting the eye, side effects of medication or injuries to the eye. Many people also experience visual disturbances due to aging or eye strain. These experiences can result in changes in your eyesight, which may sometimes cause discomfort and even make it harder to get through normal activities such as reading books 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, and struggling with 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're looking at distant objects, you may 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. Blurred vision can also mean you have astigmatism because of an irregularity in the shape of the cornea. Whatever the cause of blurry vision, it is vital that an eye doctor thoroughly check your eyes and prescribe a solution to help clarify your sight.
Sudden flashes of light, sometimes coupled with floating black spots and the sensation of a dark curtain inhabiting a part of your vision indicates the chance of what's known as a retinal detachment. In this case, see your eye doctor as soon as you can, as this can have long-term consequences.
Another warning sign of a vision problem is the inability to distinguish between different colors or brightness of color. This generally means the patient has color blindness. Color blindness is generally not known to the patient until proven with a test. Color blindness is mainly something that affects males. If present in a female it might indicate ocular disease, in which case, an eye doctor needs to be consulted. For people who have difficulty distinguishing objects in dim light, it could mean the patient suffers from night blindness.
Cataracts, a condition frequently seen elderly people can have a number of telltale signs including: hazy sight that worsens in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or objects, the need for brighter light when reading, unexpected improvement in near vision but a decline in distance vision, painful inflammation of the eye, and a pale appearance to the normally dark pupil.
Throbbing pain in the eye, headaches, unclear sight, inflammation in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, a serious medical illness, which calls for prompt medical attention.
When it comes to children, it is important to keep an eye out for weak eye movement, or crossed eyes, which may indicate a vision problem called strabismus. Certain behavior in children, like rubbing eyes, squinting, or the need to close one eye to focus better, often point to this issue.
If you experience any of the symptoms we've mentioned here, make an appointment with your eye doctor promptly. Even though some conditions could be more serious than others, any disruption to good vision will be a burden, and impact your quality of life. A brief consultation with your optometrist can prevent being avoidably uncomfortable, or even more severe eye and vision problems.
