Contacts nowadays cover only the cornea of the eyes. The designs of contact lenses today are made through a special shaping process that allows precision fitting to the curvature of the cornea; this feature is designed for minimal irritation. Common contact lenses now are soft lenses; this is usually made up of plastic material that molds its body to the shape of the cornea of its user for optimum results.
But with constant research and innovations, contact lens companies have developed a new design of contacts that is not made up of soft lens. This new breed of contacts is called the toric lenses. Toric lens is not round, rather it is oval like. Its shape provides more power and precision in one direction, either for horizontal or vertical focus.
Because this eyewear don’t really mold with the cornea of the eyes, it require certain care to keep it in good condition. Ordinary spherical contacts are worn directly at the cornea and it can move freely with the eyes. In the case of toric contacts, the user must get used to one position for best visual acuity. Too much eye movements can cause the lenses to reduce its clarity and visibility. Many contacts manufacturers right now even make heavier toric lenses to help prevent excessive eye movements that can cause the whole eyewear to reduce its quality like rotation.
Toric contacts is ideal for individuals with poor vision. This eyewear is also good for patients who suffer from astigmatism. This eyewear can reduce the cause of blurred vision; 3-5D of astigmatism is easy to aide with this type of eyewear.
Toric lenses are normally more expensive than the ordinary contacts available in the market. If you are planning to purchase this eyewear for your astigmatism problems, it is advisable that you visit your eye doctor first and ask for his or her prescription. Because of its different shape, this lens requires professional help to get that perfect fit and vision.
