Do You Experience Loss of Vision? By Steven A Johnson At Isnare.com Ezine Articles

As we get older most of us experience changes in vision that can include loss of vision, distortion of vision and blurred vision. People with loss of vision might not see anything at all or they might not be able to distinguish the difference from light and dark or my not be able to see indistinct shapes. It can happen in one or both eyes and it can happen suddenly or gradually. A gradual loss of vision may not be noticed right away or all until something like a car accident happens and they couldn’t see.

Common causes are blockage of the blood supply to the retina, disorders that damage the optic nerve, diabetes, cataracts, glaucoma, and injuries to the eyes, macular degeneration, and certain eye infections. Sometimes losses of vision can e temporary as well. Sometimes only part of the vision may be lost as well. Sometimes loss of the middle part of the visual field is lost and sometimes only peripheral vision is lost. It all varies on what is wrong with your eyes.

Many people that are legally blind can determine shapes and shadows but can define normal detail. In blind peoples eyes the passage is blocked that lets light from the environment into the back of the eye or is disrupted by transmission of nerve impulses from the back of the eye.

Distortion of the eye is described as an inability to see clearly and correctly. It can be a number of things like floaters in the eyes, flashes of light, glare, double vision, lack of depth perception, and poor focus because of refractive error. A refractive error is an inability of the eye to proper focus an image onto the retina. Astigmatism is a type of refractive error; it is when the cornea is irregularly curved. This can result in horizontal lines being in focus but vertical line being blurred. The irregular curving of the eye can occur in any direction and can be different in both eyes. It can be treated with corrective contacts and or refractive surgery. The blurred vision from refractive error can usually be fully corrected.

Allergies, fatigue, infections, abrasions, ulcers in t he cornea can cause changes in the appearance of eyes. It can cause redness due to the dilation and restriction of blood vessels. Dilation of the eye can cause inflammation; these conditions can also cause pain in the eye. Pain can occur in the eye, around it, and behind the eye. Sharp eye pain can be worsened by blinking.

If you have any problems with your eyes and have not got them checked by an eye doctor recently it may be a good idea to do so and to not drive a car during the day or night just to be safe. Loss of vision happens a lot with old age so after the age of 50 it is recommended to get eyes checked every year to make sure that there aren’t any developing problems.
