Astigmatism is amongst the most complicated terms inside the entire optical world. Many people know that they have astigmatism, but numerous people do not entirely realize what it usually means. Most adults do have some degree of astigmatism. The severity of the astigmatism determines whether it may or may not influence their overall eyesight.
Astigmatism occurs if the cornea does not have its usual spherical shape in the eye. This incorrect curvature from the cornea causes light to get refracted from the eye improperly. When light is not dealt with from the eye accurately, it may possibly make viewing objects and other scenery complicated. For people with astigmatism, viewing at any distance may perhaps be hard to do.
Those with astigmatism typically experience a variety of symptoms from headaches and eye strain to blurred vision and eye exhaustion. Though some people are born with a curvature on the cornea, some will only experience it later in life as a result of eye injuries or other eye diseases. If you detect any changes in your vision or experience the above mentioned symptoms, it is necessary to visit the optometrist right away.
This situation is easily treatable in most people. Toric lenses may be prescribed by the optometrist to correctly adjust for astigmatism. These lenses bend the light in numerous methods to account for how the cornea is reacting to light coming into the eyes. Laser surgical procedure is another choice to lessen the effect of astigmatism. However, most people favor the much less invasive approach to contact lenses or eyeglasses and will forgo a surgical procedure.
For all those with astigmatism who do not have farsightedness or nearsightedness, vision correction may not be required. It is entirely possible to have a minor astigmatism and not have any vision impact or any other medical symptoms from this defect within the cornea. It is still beneficial to know if you have astigmatism though as it could worsen over time.
For other people where the astigmatism is significant or is accompanied by farsightedness or nearsightedness, vision correction might be desired. This can easily be accomplished through wearing specially formulated eyeglasses or contact lenses. A simple eye examination with a professional optometrist can tell you for certain if you have astigmatism. At that time, he or she can talk with you to decide on a corrective form of action depending on how your eyesight is being affected and the symptoms you may have.
