Article Tags: ,

Visual blurriness, vision distortion and visual loss widely occur in old individuals all over the world. Of course vision loss is more serious. But loss of vision also has different degrees that some people suffering vision loss can not see anything at all while in slight cases only abilities such as distinguishing shapes are unavailable. Vision loss could happen to either two eyes or a single eye.

There are quite a few possible causes of vision loss. In fact, an accident that leads to an injury in the eye can also contribute to the loss of vision. In this article, we describe those factors associated with body health. As mentioned above, vision loss mostly happen to the elderly population because they are more vulnerable to different kinds of vision problems such as inadequate blood supply to the retina, disorders in the optic nerve, diabetes, cataracts, glaucoma, macular degeneration as well as others. All these conditions in the old may cause vision loss more or less.

In detail, these eye problems may affect different parts of the eye. For example, age related macular degeneration only damages the central vision and leaves peripheral vision untouched. What’s more, the degree of vision loss is always determined by the severity of the eye problem that causes it. Severe vision loss is much probably lead to blindness. While legally blind people can still determine shapes and shadows, blind individuals may completely lose their eyesight.

A slighter condition listed in the first paragraph is visual distortion, which means an inability to see clearly and correctly. Vision distortion is a generic concept that it can be used to describe several concrete conditions such as eye floaters, flashes, glare, double vision, lack of depth perception, poor focus and so on. Vision distortion can also be referred to refractive errors including nearsightedness, farsightedness and astigmatism.

Except for vision loss and visual distortion, eye appearance is another aspect that needs proper care. There are many factors that can affect one’s eye look, including allergies, fatigue, infections, abrasions, ulcers etc.
