Eye defects, such as myopia, farsightedness, astigmatism, glaucoma, and blindness, can be present from birth or develop later in life. Many can be treated with corrective lenses or surgery, but advice from a qualified eye care specialist is essential.
Eye defects are a phenomenon that many people face on a daily basis. In some cases, eye defects are present from birth. Other types of eye defects develop later in life. There are several eye conditions that are much more common than others. Fortunately, many of these common defects can be treated effectively.
Myopia is easily one of the most common of all eye defects. Known to many as myopia, this condition allows the individual to enjoy clear vision up close, while objects become increasingly blurry the further the individual gets away from them. Nearsightedness is usually an example of birth defects of the eye, as the condition involves a lens that is thicker than normal or an eyeball that is smaller than it should be. Corrective lenses and some surgical techniques can compensate for the condition and allow the individual to enjoy a more normal range of vision.
Farsightedness or farsightedness is the opposite of myopia. People with this condition tend to have normal distance vision, but are unable to focus clearly on nearby objects. This condition is more common later in life and is usually attributed to a lens that has become too thin or a condition that has caused the eyeball to enlarge. As with nearsightedness, the use of corrective lenses can partially compensate for the condition and make it easier for the individual to enjoy reading or other activities that require clear vision of nearby objects.
Astigmatism is a defect that develops due to shifts in the curvatures along the surface of the eye. A person dealing with this condition will not have clear vision in a variety of directions. A particular line of vision will be noticeably clearer than all others. Wearing corrective lenses that have different curvatures in different planes can help compensate for astigmatism.
Glaucoma is a situation in which a blind spot develops and slowly begins to expand, effectively obscuring vision. This condition is often due to pressure within the eye. Because glaucoma develops over time, patients often don’t notice a difference in vision until the disorder is diagnosed during an eye exam.
Blindness is one of the most feared eye defects by most people. In some cases, blindness is the result of sudden trauma to the ocular system, such as in an accident in which the head is injured. Other times, blindness develops over time as a particular physical condition escalates. People with diabetes are more susceptible than others to vision loss and need to take special precautions to limit the effects of the disease on eye function.
Often, eye defects can be treated or managed in some way. Along with nutrition and corrective eyewear, there are also surgical options that can help partially or completely restore full vision. However, not everyone who suffers from eye problems will experience the same level of response to any given treatment, or even be able to benefit from all available treatments. Advice from a qualified eye care specialist is essential in identifying and implementing the most practical course of treatment.
